Overcoming Speech Impediment: Symptoms to Treatment

There are many causes and solutions for impaired speech

• Types and Symptoms
• Speech Therapy
• Building Confidence

Speech impediments are conditions that can cause a variety of symptoms, such as an inability to understand language or speak with a stable sense of tone, speed, or fluidity. There are many different types of speech impediments, and they can begin during childhood or develop during adulthood.

Common causes include physical trauma, neurological disorders, or anxiety. If you or your child is experiencing signs of a speech impediment, you need to know that these conditions can be diagnosed and treated with professional speech therapy.

This article will discuss what you can do if you are concerned about a speech impediment and what you can expect during your diagnostic process and therapy.

Types and Symptoms of Speech Impediment

People can have speech problems due to developmental conditions that begin to show symptoms during early childhood or as a result of conditions that may occur during adulthood. 

The main classifications of speech impairment are aphasia (difficulty understanding or producing the correct words or phrases) or dysarthria (difficulty enunciating words).

Often, speech problems can be part of neurological or neurodevelopmental disorders that also cause other symptoms, such as multiple sclerosis (MS) or autism spectrum disorder .

There are several different symptoms of speech impediments, and you may experience one or more.

Can Symptoms Worsen?

Most speech disorders cause persistent symptoms and can temporarily get worse when you are tired, anxious, or sick.

Symptoms of dysarthria can include:

• Slurred speech
• Slow speech
• Choppy speech
• Hesitant speech
• Inability to control the volume of your speech
• Shaking or tremulous speech pattern
• Inability to pronounce certain sounds

Symptoms of aphasia may involve:

• Speech apraxia (difficulty coordinating speech)
• Difficulty understanding the meaning of what other people are saying
• Inability to use the correct words
• Inability to repeat words or phases
• Speech that has an irregular rhythm

You can have one or more of these speech patterns as part of your speech impediment, and their combination and frequency will help determine the type and cause of your speech problem.

Causes of Speech Impediment

The conditions that cause speech impediments can include developmental problems that are present from birth, neurological diseases such as Parkinson’s disease , or sudden neurological events, such as a stroke .

Some people can also experience temporary speech impairment due to anxiety, intoxication, medication side effects, postictal state (the time immediately after a seizure), or a change of consciousness.

Speech Impairment in Children

Children can have speech disorders associated with neurodevelopmental problems, which can interfere with speech development. Some childhood neurological or neurodevelopmental disorders may cause a regression (backsliding) of speech skills.

Common causes of childhood speech impediments include:

• Autism spectrum disorder : A neurodevelopmental disorder that affects social and interactive development
• Cerebral palsy :  A congenital (from birth) disorder that affects learning and control of physical movement
• Hearing loss : Can affect the way children hear and imitate speech
• Rett syndrome : A genetic neurodevelopmental condition that causes regression of physical and social skills beginning during the early school-age years.
• Adrenoleukodystrophy : A genetic disorder that causes a decline in motor and cognitive skills beginning during early childhood
• Childhood metabolic disorders : A group of conditions that affects the way children break down nutrients, often resulting in toxic damage to organs
• Brain tumor : A growth that may damage areas of the brain, including those that control speech or language
• Encephalitis : Brain inflammation or infection that may affect the way regions in the brain function
• Hydrocephalus : Excess fluid within the skull, which may develop after brain surgery and can cause brain damage

Do Childhood Speech Disorders Persist?

Speech disorders during childhood can have persistent effects throughout life. Therapy can often help improve speech skills.

Speech Impairment in Adulthood

Adult speech disorders develop due to conditions that damage the speech areas of the brain.

Common causes of adult speech impairment include:

• Head trauma 
• Nerve injury
• Throat tumor
• Stroke 
• Parkinson’s disease 
• Essential tremor
• Brain tumor
• Brain infection

Additionally, people may develop changes in speech with advancing age, even without a specific neurological cause. This can happen due to presbyphonia , which is a change in the volume and control of speech due to declining hormone levels and reduced elasticity and movement of the vocal cords.

Do Speech Disorders Resolve on Their Own?

Children and adults who have persistent speech disorders are unlikely to experience spontaneous improvement without therapy and should seek professional attention.

Steps to Treating Speech Impediment 

If you or your child has a speech impediment, your healthcare providers will work to diagnose the type of speech impediment as well as the underlying condition that caused it. Defining the cause and type of speech impediment will help determine your prognosis and treatment plan.

Sometimes the cause is known before symptoms begin, as is the case with trauma or MS. Impaired speech may first be a symptom of a condition, such as a stroke that causes aphasia as the primary symptom.

The diagnosis will include a comprehensive medical history, physical examination, and a thorough evaluation of speech and language. Diagnostic testing is directed by the medical history and clinical evaluation.

Diagnostic testing may include:

• Brain imaging , such as brain computerized tomography (CT) or magnetic residence imaging (MRI), if there’s concern about a disease process in the brain
• Swallowing evaluation if there’s concern about dysfunction of the muscles in the throat
• Electromyography (EMG) and nerve conduction studies (aka nerve conduction velocity, or NCV) if there’s concern about nerve and muscle damage
• Blood tests, which can help in diagnosing inflammatory disorders or infections

Your diagnostic tests will help pinpoint the cause of your speech problem. Your treatment will include specific therapy to help improve your speech, as well as medication or other interventions to treat the underlying disorder.

For example, if you are diagnosed with MS, you would likely receive disease-modifying therapy to help prevent MS progression. And if you are diagnosed with a brain tumor, you may need surgery, chemotherapy, or radiation to treat the tumor.

Therapy to Address Speech Impediment

Therapy for speech impairment is interactive and directed by a specialist who is experienced in treating speech problems . Sometimes, children receive speech therapy as part of a specialized learning program at school.

The duration and frequency of your speech therapy program depend on the underlying cause of your impediment, your improvement, and approval from your health insurance.

If you or your child has a serious speech problem, you may qualify for speech therapy. Working with your therapist can help you build confidence, particularly as you begin to see improvement.

Exercises during speech therapy may include:

• Pronouncing individual sounds, such as la la la or da da da
• Practicing pronunciation of words that you have trouble pronouncing
• Adjusting the rate or volume of your speech
• Mouth exercises
• Practicing language skills by naming objects or repeating what the therapist is saying

These therapies are meant to help achieve more fluent and understandable speech as well as an increased comfort level with speech and language.

Building Confidence With Speech Problems 

Some types of speech impairment might not qualify for therapy. If you have speech difficulties due to anxiety or a social phobia or if you don’t have access to therapy, you might benefit from activities that can help you practice your speech. 

You might consider one or more of the following for you or your child:

• Joining a local theater group
• Volunteering in a school or community activity that involves interaction with the public
• Signing up for a class that requires a significant amount of class participation
• Joining a support group for people who have problems with speech

Activities that you do on your own to improve your confidence with speaking can be most beneficial when you are in a non-judgmental and safe space.

Many different types of speech problems can affect children and adults. Some of these are congenital (present from birth), while others are acquired due to health conditions, medication side effects, substances, or mood and anxiety disorders. Because there are so many different types of speech problems, seeking a medical diagnosis so you can get the right therapy for your specific disorder is crucial.

Articulation Errors

Ankyloglossia, treating speech disorders.

A speech impediment, also known as a speech disorder , is a condition that can affect a person’s ability to form sounds and words, making their speech difficult to understand.

Speech disorders generally become evident in early childhood, as children start speaking and learning language. While many children initially have trouble with certain sounds and words, most are able to speak easily by the time they are five years old. However, some speech disorders persist. Approximately 5% of children aged three to 17 in the United States experience speech disorders.

There are many different types of speech impediments, including:

• Articulation errors

This article explores the causes, symptoms, and treatment of the different types of speech disorders.

Speech impediments that break the flow of speech are known as disfluencies. Stuttering is the most common form of disfluency, however there are other types as well.

Symptoms and Characteristics of Disfluencies

These are some of the characteristics of disfluencies:

• Repeating certain phrases, words, or sounds after the age of 4 (For example: “O…orange,” “I like…like orange juice,” “I want…I want orange juice”)
• Adding in extra sounds or words into sentences (For example: “We…uh…went to buy…um…orange juice”)
• Elongating words (For example: Saying “orange joooose” instead of "orange juice")
• Replacing words (For example: “What…Where is the orange juice?”)
• Hesitating while speaking (For example: A long pause while thinking)
• Pausing mid-speech (For example: Stopping abruptly mid-speech, due to lack of airflow, causing no sounds to come out, leading to a tense pause)

In addition, someone with disfluencies may also experience the following symptoms while speaking:

• Vocal tension and strain
• Head jerking
• Eye blinking
• Lip trembling

Causes of Disfluencies

People with disfluencies tend to have neurological differences in areas of the brain that control language processing and coordinate speech, which may be caused by:

• Genetic factors
• Trauma or infection to the brain
• Environmental stressors that cause anxiety or emotional distress
• Neurodevelopmental conditions like attention-deficit hyperactivity disorder (ADHD)

Articulation disorders occur when a person has trouble placing their tongue in the correct position to form certain speech sounds. Lisping is the most common type of articulation disorder.

Symptoms and Characteristics of Articulation Errors

These are some of the characteristics of articulation disorders:

• Substituting one sound for another . People typically have trouble with ‘r’ and ‘l’ sounds. (For example: Being unable to say “rabbit” and saying “wabbit” instead)
• Lisping , which refers specifically to difficulty with ‘s’ and ‘z’ sounds. (For example: Saying “thugar” instead of “sugar” or producing a whistling sound while trying to pronounce these letters)
• Omitting sounds (For example: Saying “coo” instead of “school”)
• Adding sounds (For example: Saying “pinanio” instead of “piano”)
• Making other speech errors that can make it difficult to decipher what the person is saying. For instance, only family members may be able to understand what they’re trying to say.

Causes of Articulation Errors

Articulation errors may be caused by:

• Genetic factors, as it can run in families
• Hearing loss , as mishearing sounds can affect the person’s ability to reproduce the sound
• Changes in the bones or muscles that are needed for speech, including a cleft palate (a hole in the roof of the mouth) and tooth problems
• Damage to the nerves or parts of the brain that coordinate speech, caused by conditions such as cerebral palsy , for instance

Ankyloglossia, also known as tongue-tie, is a condition where the person’s tongue is attached to the bottom of their mouth. This can restrict the tongue’s movement and make it hard for the person to move their tongue.

Symptoms and Characteristics of Ankyloglossia

Ankyloglossia is characterized by difficulty pronouncing ‘d,’ ‘n,’ ‘s,’ ‘t,’ ‘th,’ and ‘z’ sounds that require the person’s tongue to touch the roof of their mouth or their upper teeth, as their tongue may not be able to reach there.

Apart from speech impediments, people with ankyloglossia may also experience other symptoms as a result of their tongue-tie. These symptoms include:

• Difficulty breastfeeding in newborns
• Trouble swallowing
• Limited ability to move the tongue from side to side or stick it out
• Difficulty with activities like playing wind instruments, licking ice cream, or kissing
• Mouth breathing

Causes of Ankyloglossia

Ankyloglossia is a congenital condition, which means it is present from birth. A tissue known as the lingual frenulum attaches the tongue to the base of the mouth. People with ankyloglossia have a shorter lingual frenulum, or it is attached further along their tongue than most people’s.

Dysarthria is a condition where people slur their words because they cannot control the muscles that are required for speech, due to brain, nerve, or organ damage.

Symptoms and Characteristics of Dysarthria

Dysarthria is characterized by:

• Slurred, choppy, or robotic speech
• Rapid, slow, or soft speech
• Breathy, hoarse, or nasal voice

Additionally, someone with dysarthria may also have other symptoms such as difficulty swallowing and inability to move their tongue, lips, or jaw easily.

Causes of Dysarthria

Dysarthria is caused by paralysis or weakness of the speech muscles. The causes of the weakness can vary depending on the type of dysarthria the person has:

• Central dysarthria is caused by brain damage. It may be the result of neuromuscular diseases, such as cerebral palsy, Huntington’s disease, multiple sclerosis, muscular dystrophy, Huntington’s disease, Parkinson’s disease, or Lou Gehrig’s disease. Central dysarthria may also be caused by injuries or illnesses that damage the brain, such as dementia, stroke, brain tumor, or traumatic brain injury .
• Peripheral dysarthria is caused by damage to the organs involved in speech. It may be caused by congenital structural problems, trauma to the mouth or face, or surgery to the tongue, mouth, head, neck, or voice box.

Apraxia, also known as dyspraxia, verbal apraxia, or apraxia of speech, is a neurological condition that can cause a person to have trouble moving the muscles they need to create sounds or words. The person’s brain knows what they want to say, but is unable to plan and sequence the words accordingly.

Symptoms and Characteristics of Apraxia

These are some of the characteristics of apraxia:

• Distorting sounds: The person may have trouble pronouncing certain sounds, particularly vowels, because they may be unable to move their tongue or jaw in the manner required to produce the right sound. Longer or more complex words may be especially harder to manage.
• Being inconsistent in their speech: For instance, the person may be able to pronounce a word correctly once, but may not be able to repeat it. Or, they may pronounce it correctly today and differently on another day.
• Grasping for words: The person may appear to be searching for the right word or sound, or attempt the pronunciation several times before getting it right.
• Making errors with the rhythm or tone of speech: The person may struggle with using tone and inflection to communicate meaning. For instance, they may not stress any of the words in a sentence, have trouble going from one syllable in a word to another, or pause at an inappropriate part of a sentence.

Causes of Apraxia

Apraxia occurs when nerve pathways in the brain are interrupted, which can make it difficult for the brain to send messages to the organs involved in speaking. The causes of these neurological disturbances can vary depending on the type of apraxia the person has:

• Childhood apraxia of speech (CAS): This condition is present from birth and is often hereditary. A person may be more likely to have it if a biological relative has a learning disability or communication disorder.
• Acquired apraxia of speech (AOS): This condition can occur in adults, due to brain damage as a result of a tumor, head injury , stroke, or other illness that affects the parts of the brain involved in speech.

If you have a speech impediment, or suspect your child might have one, it can be helpful to visit your healthcare provider. Your primary care physician can refer you to a speech-language pathologist, who can evaluate speech, diagnose speech disorders, and recommend treatment options.

The diagnostic process may involve a physical examination as well as psychological, neurological, or hearing tests, in order to confirm the diagnosis and rule out other causes.

Treatment for speech disorders often involves speech therapy, which can help you learn how to move your muscles and position your tongue correctly in order to create specific sounds. It can be quite effective in improving your speech.

Children often grow out of milder speech disorders; however, special education and speech therapy can help with more serious ones.

For ankyloglossia, or tongue-tie, a minor surgery known as a frenectomy can help detach the tongue from the bottom of the mouth.

A Word From Verywell

A speech impediment can make it difficult to pronounce certain sounds, speak clearly, or communicate fluently. 

Living with a speech disorder can be frustrating because people may cut you off while you’re speaking, try to finish your sentences, or treat you differently. It can be helpful to talk to your healthcare providers about how to cope with these situations.

You may also benefit from joining a support group, where you can connect with others living with speech disorders.

• Patient Care & Health Information
• Diseases & Conditions

Dysarthria occurs when the muscles you use for speech are weak or you have difficulty controlling them. Dysarthria often causes slurred or slow speech that can be difficult to understand.

Common causes of dysarthria include nervous system disorders and conditions that cause facial paralysis or tongue or throat muscle weakness. Certain medications also can cause dysarthria.

Treating the underlying cause of your dysarthria may improve your speech. You may also need speech therapy. For dysarthria caused by prescription medications, changing or discontinuing the medications may help.

Signs and symptoms of dysarthria vary, depending on the underlying cause and the type of dysarthria. They may include:

• Slurred speech
• Slow speech
• Inability to speak louder than a whisper or speaking too loudly
• Rapid speech that is difficult to understand
• Nasal, raspy or strained voice
• Uneven or abnormal speech rhythm
• Uneven speech volume
• Monotone speech
• Difficulty moving your tongue or facial muscles

When to see a doctor

Dysarthria can be a sign of a serious condition. See your doctor if you have sudden or unexplained changes in your ability to speak.

In dysarthria, you may have difficulty moving the muscles in your mouth, face or upper respiratory system that control speech. Conditions that may lead to dysarthria include:

• Amyotrophic lateral sclerosis (ALS, or Lou Gehrig's disease)
• Brain injury
• Brain tumor
• Cerebral palsy
• Guillain-Barre syndrome
• Head injury
• Huntington's disease
• Lyme disease
• Multiple sclerosis
• Muscular dystrophy
• Myasthenia gravis
• Parkinson's disease
• Wilson's disease

Some medications, such as certain sedatives and seizure drugs, also can cause dysarthria.

Complications

Because of the communication problems dysarthria causes, complications can include:

• Social difficulty. Communication problems may affect your relationships with family and friends and make social situations challenging.
• Depression. In some people, dysarthria may lead to social isolation and depression.

What Is a Speech Impediment?

Types of speech disorders, speech impediment causes, how to fix a speech impediment, making a difference in speech disorders.

Communication is a cornerstone of human relationships. When an individual struggles to verbalize information, thoughts, and feelings, it can cause major barriers in personal, learning, and business interactions.

Speech impediments, or speech disorders, can lead to feelings of insecurity and frustration. They can also cause worry for family members and friends who don’t know how to help their loved ones express themselves.

Fortunately, there are a number of ways that speech disorders can be treated, and in many cases, cured. Health professionals in fields including speech-language pathology and audiology can work with patients to overcome communication disorders, and individuals and families can learn techniques to help.

Commonly referred to as a speech disorder, a speech impediment is a condition that impacts an individual’s ability to speak fluently, correctly, or with clear resonance or tone. Individuals with speech disorders have problems creating understandable sounds or forming words, leading to communication difficulties.

Some 7.7% of U.S. children — or 1 in 12 youths between the ages of 3 and 17 — have speech, voice, language, or swallowing disorders, according to the National Institute on Deafness and Other Communication Disorders (NIDCD). About 70 million people worldwide, including some 3 million Americans, experience stuttering difficulties, according to the Stuttering Foundation.

Common signs of a speech disorder

There are several symptoms and indicators that can point to a speech disorder.

• Unintelligible speech — A speech disorder may be present when others have difficulty understanding a person’s verbalizations.
• Omitted sounds — This symptom can include the omission of part of a word, such as saying “bo” instead of “boat,” and may include omission of consonants or syllables.
• Added sounds — This can involve adding extra sounds in a word, such as “buhlack” instead of “black,” or repeating sounds like “b-b-b-ball.”
• Substituted sounds — When sounds are substituted or distorted, such as saying “wabbit” instead of “rabbit,” it may indicate a speech disorder.
• Use of gestures — When individuals use gestures to communicate instead of words, a speech impediment may be the cause.
• Inappropriate pitch — This symptom is characterized by speaking with a strange pitch or volume.

In children, signs might also include a lack of babbling or making limited sounds. Symptoms may also include the incorrect use of specific sounds in words, according to the American Speech-Language-Hearing Association (ASHA). This may include the sounds p, m, b, w, and h among children aged 1-2, and k, f, g, d, n, and t for children aged 2-3.

Categories of Speech Impediments

Speech impediments can range from speech sound disorders (articulation and phonological disorders) to voice disorders. Speech sound disorders may be organic — resulting from a motor or sensory cause — or may be functional with no known cause. Voice disorders deal with physical problems that limit speech. The main categories of speech impediments include the following:

Fluency disorders occur when a patient has trouble with speech timing or rhythms. This can lead to hesitations, repetitions, or prolonged sounds. Fluency disorders include stuttering (repetition of sounds) or   (rapid or irregular rate of speech).

Resonance disorders are related to voice quality that is impacted by the shape of the nose, throat, and/or mouth. Examples of resonance disorders include hyponasality and cul-de-sac resonance.

Articulation disorders occur when a patient has difficulty producing speech sounds. These disorders may stem from physical or anatomical limitations such as muscular, neuromuscular, or skeletal support. Examples of articulation speech impairments include sound omissions, substitutions, and distortions.

Phonological disorders result in the misuse of certain speech sounds to form words. Conditions include fronting, stopping, and the omission of final consonants.

Voice disorders are the result of problems in the larynx that harm the quality or use of an individual’s voice. This can impact pitch, resonance, and loudness.

Impact of Speech Disorders

Some speech disorders have little impact on socialization and daily activities, but other conditions can make some tasks difficult for individuals. Following are a few of the impacts of speech impediments.

• Poor communication — Children may be unable to participate in certain learning activities, such as answering questions or reading out loud, due to communication difficulties. Adults may avoid work or social activities such as giving speeches or attending parties.
• Mental health and confidence — Speech disorders may cause children or adults to feel different from peers, leading to a lack of self-confidence and, potentially, self-isolation.

Resources on Speech Disorders

The following resources may help those who are seeking more information about speech impediments.

Health Information : Information and statistics on common voice and speech disorders from the NIDCD

Speech Disorders : Information on childhood speech disorders from Cincinnati Children’s Hospital Medical Center

Speech, Language, and Swallowing : Resources about speech and language development from the ASHA

Children and adults can suffer from a variety of speech impairments that may have mild to severe impacts on their ability to communicate. The following 10 conditions are examples of specific types of speech disorders and voice disorders.

1. Stuttering

This condition is one of the most common speech disorders. Stuttering is the repetition of syllables or words, interruptions in speech, or prolonged use of a sound.

This organic speech disorder is a result of damage to the neural pathways that connect the brain to speech-producing muscles. This results in a person knowing what they want to say, but being unable to speak the words.

This consists of the lost ability to speak, understand, or write languages. It is common in stroke, brain tumor, or traumatic brain injury patients.

4. Dysarthria

This condition is an organic speech sound disorder that involves difficulty expressing certain noises. This may involve slurring, or poor pronunciation, and rhythm differences related to nerve or brain disorders.

The condition of lisping is the replacing of sounds in words, including “th” for “s.” Lisping is a functional speech impediment.

6. Hyponasality

This condition is a resonance disorder related to limited sound coming through the nose, causing a “stopped up” quality to speech.

7. Cul-de-sac resonance

This speech disorder is the result of blockage in the mouth, throat, or nose that results in quiet or muffled speech.

8. Orofacial myofunctional disorders

These conditions involve abnormal patterns of mouth and face movement. Conditions include tongue thrusting (fronting), where individuals push out their tongue while eating or talking.

9. Spasmodic Dysphonia

This condition is a voice disorder in which spasms in the vocal cords produce speech that is hoarse, strained, or jittery.

10. Other voice disorders

These conditions can include having a voice that sounds breathy, hoarse, or scratchy. Some disorders deal with vocal folds closing when they should open (paradoxical vocal fold movement) or the presence of polyps or nodules in the vocal folds.

Speech Disorders vs. Language Disorders

Speech disorders deal with difficulty in creating sounds due to articulation, fluency, phonology, and voice problems. These problems are typically related to physical, motor, sensory, neurological, or mental health issues.

Language disorders, on the other hand, occur when individuals have difficulty communicating the meaning of what they want to express. Common in children, these disorders may result in low vocabulary and difficulty saying complex sentences. Such a disorder may reflect difficulty in comprehending school lessons or adopting new words, or it may be related to a learning disability such as dyslexia. Language disorders can also involve receptive language difficulties, where individuals have trouble understanding the messages that others are trying to convey.

Speech disorders may be caused by a variety of factors related to physical features, neurological ailments, or mental health conditions. In children, they may be related to developmental issues or unknown causes and may go away naturally over time.

Physical and neurological issues. Speech impediment causes related to physical characteristics may include:

• Brain damage
• Nervous system damage
• Respiratory system damage
• Hearing difficulties
• Cancerous or noncancerous growths
• Muscle and bone problems such as dental issues or cleft palate

Mental health issues. Some speech disorders are related to clinical conditions such as:

• Autism spectrum disorder
• Down syndrome or other genetic syndromes
• Cerebral palsy or other neurological disorders
• Multiple sclerosis

Some speech impairments may also have to do with family history, such as when parents or siblings have experienced language or speech difficulties. Other causes may include premature birth, pregnancy complications, or delivery difficulties. Voice overuse and chronic coughs can also cause speech issues.

The most common way that speech disorders are treated involves seeking professional help. If patients and families feel that symptoms warrant therapy, health professionals can help determine how to fix a speech impediment. Early treatment is best to curb speech disorders, but impairments can also be treated later in life.

Professionals in the speech therapy field include speech-language pathologists (SLPs) . These practitioners assess, diagnose, and treat communication disorders including speech, language, social, cognitive, and swallowing disorders in both adults and children. They may have an SLP assistant to help with diagnostic and therapy activities.

Speech-language pathologists may also share a practice with audiologists and audiology assistants. Audiologists help identify and treat hearing, balance, and other auditory disorders.

How Are Speech Disorders Diagnosed?

Typically, a pediatrician, social worker, teacher, or other concerned party will recognize the symptoms of a speech disorder in children. These individuals, who frequently deal with speech and language conditions and are more familiar with symptoms, will recommend that parents have their child evaluated. Adults who struggle with speech problems may seek direct guidance from a physician or speech evaluation specialist.

When evaluating a patient for a potential speech impediment, a physician will:

• Conduct hearing and vision tests
• Evaluate patient records
• Observe patient symptoms

A speech-language pathologist will conduct an initial screening that might include:

• An evaluation of speech sounds in words and sentences
• An evaluation of oral motor function
• An orofacial examination
• An assessment of language comprehension

The initial screening might result in no action if speech symptoms are determined to be developmentally appropriate. If a disorder is suspected, the initial screening might result in a referral for a comprehensive speech sound assessment, comprehensive language assessment, audiology evaluation, or other medical services.

Initial assessments and more in-depth screenings might occur in a private speech therapy practice, rehabilitation center, school, childcare program, or early intervention center. For older adults, skilled nursing centers and nursing homes may assess patients for speech, hearing, and language disorders.

How Are Speech Impediments Treated?

Once an evaluation determines precisely what type of speech sound disorder is present, patients can begin treatment. Speech-language pathologists use a combination of therapy, exercise, and assistive devices to treat speech disorders.

Speech therapy might focus on motor production (articulation) or linguistic (phonological or language-based) elements of speech, according to ASHA. There are various types of speech therapy available to patients.

Contextual Utilization  — This therapeutic approach teaches methods for producing sounds consistently in different syllable-based contexts, such as phonemic or phonetic contexts. These methods are helpful for patients who produce sounds inconsistently.

Phonological Contrast — This approach focuses on improving speech through emphasis of phonemic contrasts that serve to differentiate words. Examples might include minimal opposition words (pot vs. spot) or maximal oppositions (mall vs. call). These therapy methods can help patients who use phonological error patterns.

Distinctive Feature — In this category of therapy, SLPs focus on elements that are missing in speech, such as articulation or nasality. This helps patients who substitute sounds by teaching them to distinguish target sounds from substituted sounds.

Core Vocabulary — This therapeutic approach involves practicing whole words that are commonly used in a specific patient’s communications. It is effective for patients with inconsistent sound production.

Metaphon — In this type of therapy, patients are taught to identify phonological language structures. The technique focuses on contrasting sound elements, such as loud vs. quiet, and helps patients with unintelligible speech issues.

Oral-Motor — This approach uses non-speech exercises to supplement sound therapies. This helps patients gain oral-motor strength and control to improve articulation.

Other methods professionals may use to help fix speech impediments include relaxation, breathing, muscle strengthening, and voice exercises. They may also recommend assistive devices, which may include:

• Radio transmission systems
• Personal amplifiers
• Picture boards
• Touch screens
• Text displays
• Speech-generating devices
• Hearing aids
• Cochlear implants

Speech Disorder Tips for Families

For parents who are concerned that their child might have a speech disorder — or who want to prevent the development of a disorder — there are a number of activities that can help. The following are tasks that parents can engage in on a regular basis to develop literacy and speech skills.

• Introducing new vocabulary words
• Reading picture and story books with various sounds and patterns
• Talking to children about objects and events
• Answering children’s questions during routine activities
• Encouraging drawing and scribbling
• Pointing to words while reading books
• Pointing out words and sentences in objects and signs

Parents can take the following steps to make sure that potential speech impediments are identified early on.

• Discussing concerns with physicians
• Asking for hearing, vision, and speech screenings from doctors
• Requesting special education assessments from school officials
• Requesting a referral to a speech-language pathologist, audiologist, or other specialist

When a child is engaged in speech therapy, speech-language pathologists will typically establish collaborative relationships with families, sharing information and encouraging parents to participate in therapy decisions and practices.

SLPs will work with patients and their families to set goals for therapy outcomes. In addition to therapy sessions, they may develop activities and exercises for families to work on at home. It is important that caregivers are encouraging and patient with children during therapy.

If identified during childhood, speech disorders can be corrected efficiently, giving children greater communication opportunities. If left untreated, speech impediments can cause a variety of problems in adulthood, and may be more difficult to diagnose and treat.

Parents, teachers, doctors, speech and language professionals, and other concerned parties all have unique responsibilities in recognizing and treating speech disorders. Through professional therapy, family engagement, positive encouragement and a strong support network, individuals with speech impediments can overcome their challenges and develop essential communication skills.

Speech impairment in adults

Speech and language impairment may be any of several problems that make it difficult to communicate.

Considerations

The following are common speech and language disorders.

Aphasia is loss of the ability to understand or express spoken or written language. It commonly occurs after strokes or traumatic brain injuries. It can also occur in people with brain tumors or degenerative diseases that affect the language areas of the brain. This term does not apply to children who have never developed communication skills. There are many different types of aphasia.

In some cases of aphasia, the problem eventually corrects itself, but in others, it doesn't get better.

With dysarthria , the person has problems expressing certain sounds or words. They have poorly pronounced speech (such as slurring) and the rhythm or speed of speech is changed. Usually, a nerve or brain disorder has made it difficult to control the tongue, lips, larynx, or vocal cords, which make speech.

Dysarthria, which is difficulty pronouncing words, is sometimes confused with aphasia, which is difficulty producing language. They have different causes.

People with dysarthria may also have problems swallowing.

VOICE DISTURBANCES

Anything that changes the shape of the vocal cords or the way they work will cause a voice disturbance. Lump-like growths such as nodules, polyps, cysts, papillomas, granulomas, and cancers can be to blame. These changes cause the voice to sound different from the way it normally sounds.

Some of these disorders develop gradually, but anyone can develop a speech and language impairment suddenly, usually due to a stroke or trauma.

• Alzheimer disease
• Brain tumor (more common in aphasia than dysarthria)
• Head trauma
• Transient ischemic attack (TIA)
• Alcohol intoxication
• Diseases that affect nerves and muscles (neuromuscular diseases), such as amyotrophic lateral sclerosis (ALS or Lou Gehrig disease), cerebral palsy, myasthenia gravis, or multiple sclerosis (MS)
• Facial trauma
• Facial weakness, such as Bell's palsy or tongue weakness
• Head and neck cancer surgery
• Nervous system (neurological) disorders that affect the brain, such as Parkinson disease or Huntington disease (more common in dysarthria than aphasia)
• Poorly fitting dentures
• Side effects of medicines that act on the central nervous system, such as narcotics, phenytoin, or carbamazepine
• Growths or nodules on the vocal cords
• People who use their voice heavily (teachers, coaches, vocal performers) are more likely to develop voice disorders.

For dysarthria, ways to help improve communication include speaking slowly and using hand gestures. Family and friends need to provide plenty of time for those with the disorder to express themselves. Typing on an electronic device or using pen and paper can also help with communication.

For aphasia, family members may need to provide frequent orientation reminders, such as the day of the week. Disorientation and confusion often occur with aphasia.Using nonverbal ways of communicating may also help.

It's important to maintain a relaxed, calm environment and keep external stimuli to a minimum.

• Speak in a normal tone of voice (this condition is not a hearing or emotional problem).
• Use simple phrases to avoid misunderstandings.
• Don't assume that the person understands.
• Provide communication aids, if possible, depending on the person and condition.

Mental health counseling may help with depression or frustration that many people with speech impairment have.

When to Contact a Medical Professional

Contact the provider if:

• Impairment or loss of communication comes on suddenly
• There is any unexplained impairment of speech or written language

What to Expect at Your Office Visit

Unless the problems have developed after an emergency event, the provider will take a medical history and perform a physical exam. The medical history may require the assistance of family or friends.

The provider will likely ask about the speech impairment. Questions may include when the problem developed, whether there was an injury, and what medicines the person takes.

Diagnostic tests that may be performed include the following:

• Blood tests
• Cerebral angiography to check blood flow in the brain
• CT or MRI scan of the head to check for problems such as tumor
• Electroencephalogram (EEG) to measure electrical activity of the brain
• Electromyography ( EMG ) to check the health of the muscles and the nerves that control the muscles
• Lumbar puncture to check the cerebrospinal fluid that surrounds the brain and spinal cord
• Urine tests
• X-rays of the skull

If the tests find other medical problems, other specialist doctors will need to be consulted.

For help with the speech problem, a speech and language therapist or social worker will likely need to be consulted.

Speaking clearly: Help for people with speech and language disorders

• Speech-Language

Speaking and language abilities vary from person to person. Some people can quickly articulate exactly what they are thinking or feeling, while others struggle being understood or finding the right words.

These struggles could be due to a speech or language disorder if communication struggles cause ongoing communication challenges and frustrations. Speech and language disorders are common.

It's estimated that 5% to 10% of people in the U.S. have a communication disorder. By the first grade, about 5% of U.S. children have a noticeable speech disorder. About 3 million U.S. adults struggle with stuttering and about 1 million U.S. adults have aphasia. These conditions make reading, speaking, writing and comprehending difficult.

People with speech and language disorders can find hope in rehabilitation. Speech-language pathologists can evaluate and treat these disorders. This can lead to a happier, healthier and more expressive life.

Types of speech and language disorders

Speech and language disorders come in many forms, each with its own characteristics:.

• Aphasia People with aphasia have difficulty with reading, writing, speaking or understanding information they've heard. The intelligence of a person with aphasia is not affected.
• Dysarthria People with dysarthria demonstrate slurred or imprecise speech patterns that can affect the understanding of speech.
• Apraxia A person with this disorder has difficulty coordinating lip and tongue movements to produce understandable speech.
• Dysphagia This condition refers to swallowing difficulties, including food sticking in the throat, coughing or choking while eating or drinking, and other difficulties.
• Stuttering This speech disorder involves frequent and significant problems with normal fluency and flow of speech. People who stutter know what they want to say but have difficulty saying it.
• Articulation disorder People with this disorder have trouble learning how to make specific sounds. They may substitute sounds, such as saying "fum" instead of "thumb".
• Phonological disorder Phonological processes are patterns of errors children use to simplify language as they learn to speak. A phonological disorder may be present if these errors persist beyond the age when most other children stop using them. An example is saying "duh" instead of "duck."
• Voice Voice disorders include vocal cord paralysis, vocal abuse and vocal nodules, which could result in vocal hoarseness, changes in vocal volume and vocal fatigue.
• Cognitive communication impairment People with cognitive communication impairment have difficulty with concentration, memory, problem-solving, and completion of tasks for daily and medical needs.

Speech and language disorders are more common in children. It can take time to develop the ability to speak and communicate clearly. Some children struggle with finding the right word or getting their jaws, lips or tongues in the correct positions to make the right sounds.

In adults, speech and language disorders often are the result of a medical condition or injury. The most common of these conditions or injuries are a stroke, brain tumor, brain injury, cancer, Parkinson's disease, multiple sclerosis, Lou Gehrig's disease or other underlying health complications.

Treatment options

Speech and language disorders can be concerning, but speech-language pathologists can work with patients to evaluate and treat these conditions. Each treatment plan is specifically tailored to the patient.

Treatment plans can address difficulties with:

• Speech sounds, fluency or voice
• Understanding language
• Sharing thoughts, ideas and feelings
• Organizing thoughts, paying attention, remembering, planning or problem-solving
• Feeding and swallowing
• Vocabulary or improper grammar use

Treatment typically includes training to compensate for deficiencies; patient and family education; at-home exercises; or neurological rehabilitation to address impairments due to medical conditions, illnesses or injury.

Treatment options are extensive and not limited by age. Children and adults can experience the benefits of treatment.

If you or a loved one are struggling with speech and language issues, you are not alone. Millions of people experience similar daily challenges. Better yet, help is available.

10 Most Common Speech-Language Disorders & Impediments

As you get to know more about the field of speech-language pathology you’ll increasingly realize why SLPs are required to earn at least a master’s degree . This stuff is serious – and there’s nothing easy about it.

In 2016 the National Institute on Deafness and Other Communication Disorders reported that 7.7% of American children have been diagnosed with a speech or swallowing disorder. That comes out to nearly one in 12 children, and gets even bigger if you factor in adults.

Whether rooted in psycho-speech behavioral issues, muscular disorders, or brain damage, nearly all the diagnoses SLPs make fall within just 10 common categories…

Types of Speech Disorders & Impediments

Apraxia of speech (aos).

Apraxia of Speech (AOS) happens when the neural pathway between the brain and a person’s speech function (speech muscles) is lost or obscured. The person knows what they want to say – they can even write what they want to say on paper – however the brain is unable to send the correct messages so that speech muscles can articulate what they want to say, even though the speech muscles themselves work just fine. Many SLPs specialize in the treatment of Apraxia .

There are different levels of severity of AOS, ranging from mostly functional, to speech that is incoherent. And right now we know for certain it can be caused by brain damage, such as in an adult who has a stroke. This is called Acquired AOS.

However the scientific and medical community has been unable to detect brain damage – or even differences – in children who are born with this disorder, making the causes of Childhood AOS somewhat of a mystery. There is often a correlation present, with close family members suffering from learning or communication disorders, suggesting there may be a genetic link.

Mild cases might be harder to diagnose, especially in children where multiple unknown speech disorders may be present. Symptoms of mild forms of AOS are shared by a range of different speech disorders, and include mispronunciation of words and irregularities in tone, rhythm, or emphasis (prosody).

Stuttering – Stammering

Stuttering, also referred to as stammering, is so common that everyone knows what it sounds like and can easily recognize it. Everyone has probably had moments of stuttering at least once in their life. The National Institute on Deafness and Other Communication Disorders estimates that three million Americans stutter, and reports that of the up-to-10-percent of children who do stutter, three-quarters of them will outgrow it. It should not be confused with cluttering.

Most people don’t know that stuttering can also include non-verbal involuntary or semi-voluntary actions like blinking or abdominal tensing (tics). Speech language pathologists are trained to look for all the symptoms of stuttering , especially the non-verbal ones, and that is why an SLP is qualified to make a stuttering diagnosis.

The earliest this fluency disorder can become apparent is when a child is learning to talk. It may also surface later during childhood. Rarely if ever has it developed in adults, although many adults have kept a stutter from childhood.

Stuttering only becomes a problem when it has an impact on daily activities, or when it causes concern to parents or the child suffering from it. In some people, a stutter is triggered by certain events like talking on the phone. When people start to avoid specific activities so as not to trigger their stutter, this is a sure sign that the stutter has reached the level of a speech disorder.

The causes of stuttering are mostly a mystery. There is a correlation with family history indicating a genetic link. Another theory is that a stutter is a form of involuntary or semi-voluntary tic. Most studies of stuttering agree there are many factors involved.

Dysarthria is a symptom of nerve or muscle damage. It manifests itself as slurred speech, slowed speech, limited tongue, jaw, or lip movement, abnormal rhythm and pitch when speaking, changes in voice quality, difficulty articulating, labored speech, and other related symptoms.

It is caused by muscle damage, or nerve damage to the muscles involved in the process of speaking such as the diaphragm, lips, tongue, and vocal chords.

Because it is a symptom of nerve and/or muscle damage it can be caused by a wide range of phenomena that affect people of all ages. This can start during development in the womb or shortly after birth as a result of conditions like muscular dystrophy and cerebral palsy. In adults some of the most common causes of dysarthria are stroke, tumors, and MS.

A lay term, lisping can be recognized by anyone and is very common.

Speech language pathologists provide an extra level of expertise when treating patients with lisping disorders . They can make sure that a lisp is not being confused with another type of disorder such as apraxia, aphasia, impaired development of expressive language, or a speech impediment caused by hearing loss.

SLPs are also important in distinguishing between the five different types of lisps. Most laypersons can usually pick out the most common type, the interdental/dentalised lisp. This is when a speaker makes a “th” sound when trying to make the “s” sound. It is caused by the tongue reaching past or touching the front teeth.

Because lisps are functional speech disorders, SLPs can play a huge role in correcting these with results often being a complete elimination of the lisp. Treatment is particularly effective when implemented early, although adults can also benefit.

Experts recommend professional SLP intervention if a child has reached the age of four and still has an interdental/dentalised lisp. SLP intervention is recommended as soon as possible for all other types of lisps. Treatment includes pronunciation and annunciation coaching, re-teaching how a sound or word is supposed to be pronounced, practice in front of a mirror, and speech-muscle strengthening that can be as simple as drinking out of a straw.

Spasmodic Dysphonia

Spasmodic Dysphonia (SD) is a chronic long-term disorder that affects the voice. It is characterized by a spasming of the vocal chords when a person attempts to speak and results in a voice that can be described as shaky, hoarse, groaning, tight, or jittery. It can cause the emphasis of speech to vary considerably. Many SLPs specialize in the treatment of Spasmodic Dysphonia .

SLPs will most often encounter this disorder in adults, with the first symptoms usually occurring between the ages of 30 and 50. It can be caused by a range of things mostly related to aging, such as nervous system changes and muscle tone disorders.

It’s difficult to isolate vocal chord spasms as being responsible for a shaky or trembly voice, so diagnosing SD is a team effort for SLPs that also involves an ear, nose, and throat doctor (otolaryngologist) and a neurologist.

Have you ever heard people talking about how they are smart but also nervous in large groups of people, and then self-diagnose themselves as having Asperger’s? You might have heard a similar lay diagnosis for cluttering. This is an indication of how common this disorder is as well as how crucial SLPs are in making a proper cluttering diagnosis .

A fluency disorder, cluttering is characterized by a person’s speech being too rapid, too jerky, or both. To qualify as cluttering, the person’s speech must also have excessive amounts of “well,” “um,” “like,” “hmm,” or “so,” (speech disfluencies), an excessive exclusion or collapsing of syllables, or abnormal syllable stresses or rhythms.

The first symptoms of this disorder appear in childhood. Like other fluency disorders, SLPs can have a huge impact on improving or eliminating cluttering. Intervention is most effective early on in life, however adults can also benefit from working with an SLP.

Muteness – Selective Mutism

There are different kinds of mutism, and here we are talking about selective mutism. This used to be called elective mutism to emphasize its difference from disorders that caused mutism through damage to, or irregularities in, the speech process.

Selective mutism is when a person does not speak in some or most situations, however that person is physically capable of speaking. It most often occurs in children, and is commonly exemplified by a child speaking at home but not at school.

Selective mutism is related to psychology. It appears in children who are very shy, who have an anxiety disorder, or who are going through a period of social withdrawal or isolation. These psychological factors have their own origins and should be dealt with through counseling or another type of psychological intervention.

Diagnosing selective mutism involves a team of professionals including SLPs, pediatricians, psychologists, and psychiatrists. SLPs play an important role in this process because there are speech language disorders that can have the same effect as selective muteness – stuttering, aphasia, apraxia of speech, or dysarthria – and it’s important to eliminate these as possibilities.

And just because selective mutism is primarily a psychological phenomenon, that doesn’t mean SLPs can’t do anything. Quite the contrary.

The National Institute on Neurological Disorders and Stroke estimates that one million Americans have some form of aphasia.

Aphasia is a communication disorder caused by damage to the brain’s language capabilities. Aphasia differs from apraxia of speech and dysarthria in that it solely pertains to the brain’s speech and language center.

As such anyone can suffer from aphasia because brain damage can be caused by a number of factors. However SLPs are most likely to encounter aphasia in adults, especially those who have had a stroke. Other common causes of aphasia are brain tumors, traumatic brain injuries, and degenerative brain diseases.

In addition to neurologists, speech language pathologists have an important role in diagnosing aphasia. As an SLP you’ll assess factors such as a person’s reading and writing, functional communication, auditory comprehension, and verbal expression.

Speech Delay – Alalia

A speech delay, known to professionals as alalia, refers to the phenomenon when a child is not making normal attempts to verbally communicate. There can be a number of factors causing this to happen, and that’s why it’s critical for a speech language pathologist to be involved.

The are many potential reasons why a child would not be using age-appropriate communication. These can range anywhere from the child being a “late bloomer” – the child just takes a bit longer than average to speak – to the child having brain damage. It is the role of an SLP to go through a process of elimination, evaluating each possibility that could cause a speech delay, until an explanation is found.

Approaching a child with a speech delay starts by distinguishing among the two main categories an SLP will evaluate: speech and language.

Speech has a lot to do with the organs of speech – the tongue, mouth, and vocal chords – as well as the muscles and nerves that connect them with the brain. Disorders like apraxia of speech and dysarthria are two examples that affect the nerve connections and organs of speech. Other examples in this category could include a cleft palette or even hearing loss.

The other major category SLPs will evaluate is language. This relates more to the brain and can be affected by brain damage or developmental disorders like autism. There are many different types of brain damage that each manifest themselves differently, as well as developmental disorders, and the SLP will make evaluations for everything.

Issues Related to Autism

While the autism spectrum itself isn’t a speech disorder, it makes this list because the two go hand-in-hand more often than not.

The Centers for Disease Control and Prevention (CDC) reports that one out of every 68 children in our country have an autism spectrum disorder. And by definition, all children who have autism also have social communication problems.

Speech-language pathologists are often a critical voice on a team of professionals – also including pediatricians, occupational therapists, neurologists, developmental specialists, and physical therapists – who make an autism spectrum diagnosis .

In fact, the American Speech-Language Hearing Association reports that problems with communication are the first detectable signs of autism. That is why language disorders – specifically disordered verbal and nonverbal communication – are one of the primary diagnostic criteria for autism.

So what kinds of SLP disorders are you likely to encounter with someone on the autism spectrum?

A big one is apraxia of speech. A study that came out of Penn State in 2015 found that 64 percent of children who were diagnosed with autism also had childhood apraxia of speech.

This basic primer on the most common speech disorders offers little more than an interesting glimpse into the kind of issues that SLPs work with patients to resolve. But even knowing everything there is to know about communication science and speech disorders doesn’t tell the whole story of what this profession is all about. With every client in every therapy session, the goal is always to have the folks that come to you for help leave with a little more confidence than when they walked in the door that day. As a trusted SLP, you will build on those gains with every session, helping clients experience the joy and freedom that comes with the ability to express themselves freely. At the end of the day, this is what being an SLP is all about.

The Five Most Common Speech Disorders in Adults

Raleigh Capitol Ear, Nose and Throat Communication Disorders

Communication is a gift we take for granted. It’s easy to forget how effortless it is for many of us to speak with confidence to friends, coworkers or even family members. There are few things more frustrating than trying to express yourself when the power of speech fails you. Stuttering and other common speech disorders make it difficult to impart even the simplest ideas, and as a result can lead to social isolation and depression.

There are several different reasons adults have speech disorders, ranging from traumatic brain injuries to speech impediments that were not corrected in childhood. We’ve examined some of the most common speech disorders in adults and how they are treated.

THE FIVE MOST COMMON SPEECH DISORDERS IN ADULTS

1. stuttering.

It may come as a surprise that many famous actors and entertainers experienced stuttering, including  James Earl Jones .

According to the  American Speech-Language-Hearing Association , stuttering often begins in childhood and can last throughout someone’s life. Early intervention is vital in order to correct the problem.

WHAT CAUSES STUTTERING?

While researchers haven’t pinpointed an exact cause of stuttering, they believe there may be a genetic component—those who stutter tend to have family members who stutter.

Stuttering issues can also be compounded by external factors. Teasing from others and embarrassment contribute to anxiety, which in turn, tightens speech muscles.

HOW IS STUTTERING TREATED?

Treatment involves working with a speech pathologist. [link to RCENT page  https://www.raleighcapitolent.com/our-staff/speech-pathologists  ] These professionals work with both adults and children to treat speech, language and swallowing disorders.

Those who stutter work to control their speech rate and monitor breathing. As they practice these techniques, speech will improve over time.

If you have apraxia, your tongue and lips aren’t able to move in the correct way to produce sounds. In extreme cases, apraxia can render someone unable to speak at all. Apraxia also involves saying made up words or saying “chicken” for “kitchen,” according to information from the  American Speech-Language-Hearing Association .

WHAT CAUSES APRAXIA?

Apraxia is typically caused by stroke, dementia, brain tumors or traumatic brain injuries.

HOW IS APRAXIA TREATED?

Just as an athlete needs to train certain muscles so they will respond correctly, a speech pathologist will work with you to retrain the muscles involved in your speech. This means repeated practice of mouth movements.

3. Dysarthria

Dysarthria differs from apraxia, in that the speech muscles are weak due to brain damage. This can lead to slurred or imprecise speech.

WHAT CAUSES DYSARTHRIA?

According to the  American Speech-Language-Hearing Association , the following diseases play a major role in the development of dysarthria:

• Brain tumors
• ALS (Lou Gehrig’s Disease)
• Parkinson’s disease
• Multiple sclerosis

     HOW IS DYSARTHRIA TREATED?

Finding the correct treatment depends upon the underlying cause of dysarthria and its severity. Speech language pathologists may work with you to help slow down your speech and use your breath to speak more clearly. In addition, they will concentrate on training the muscles in your mouth, lips and tongue to make them stronger.

4. Voice disorders involving the larynx (voice box)

There are several different types of voice disorders that are caused by problems with the voice box. According to the  American Speech-Language-Hearing Association , some of these voice disorders include:

• Hoarseness  

Those who use their voice as part of their daily jobs (such as teachers and singers) are more prone to hoarseness than others, and it’s typically a temporary condition. However, chronic hoarseness may be an indicator of other problems.

• Polyps or nodules on the vocal cords

These growths make it difficult for the vocal cords to vibrate to produce speech. They are caused by a wide range of conditions ranging from allergies to smoking. Large growths are removed surgically, while smaller ones can be successfully managed by treating the underlying condition.

• Spasmodic dysphonia

This occurs when your vocal folds spasm or tighten when you speak. At times you may not be able to speak at all. It’s typically caused by problems with your nervous system or a brain disorder. While there’s no cure for this condition, your local ear, nose and throat physician may inject Botox into your vocal folds to loosen them.In addition, your speech language pathologist can provide voice therapy to help you communicate.

• Vocal fold paralysis

When your vocal folds are not able to move, it not only causes speech difficulties, but it can lead to serious breathing and swallowing problems. Sometimes, a tracheotomy (an opening in the neck) is necessary to breathe. Speech therapy may be needed in order to help prevent food from going down the “windpipe.”

Aphasia is a language disorder that is caused by damage to the left side (the “verbal” side) of your brain and is most commonly seen after a stroke. This makes it difficult to speak, read and/or understand what is being said.

WHAT ARE THE SYMPTOMS OF APHASIA?

Some of the symptoms include:

• Several instances of saying the wrong word. For example, saying “car” when you meant to say “house.”
• Switching sounds, such as saying “way drive” instead of “driveway.”
• Using made up words either on their own or in a sentence with real words.

WHAT ARE TREATMENTS FOR APHASIA?

There are several different approaches to treatment. You’ll have to work closely with your speech language health care provider to find the most effective for you. At times, this may mean learning new ways to communicate by using gestures, computers or pictures.

Rhotacism: A complete guide to this speech impediment

Remember when you were a child and spoke by making your “R’s” sound like “W’s” and everything thought it was cute? That’s known as rhotacism and some people live with it even as adults. What is rhotacism, what is it like in other languages, and what are its symptoms? What does it look like as a speech impediment and what are some examples? What are its causes? How does it affect the brain ? Is it curable and how can it be fixed? This article will answer all your doubts about rhotacism. 

What is rhotacism?

Rhotacism is a speech impediment that is defined by the lack of ability, or difficulty in, pronouncing the sound R . Some speech pathologists, those who work with speech impediments may call this impediment de-rhotacization because the sounds don’t become rhotic, rather they lose their rhotic quality. It could also be called a residual R error.

It’s not such an uncommon phenomenon and actually also happens with the letter L , a phenomenon known as lambdacism . Sometimes people mistake these speech impediments for a lisp, of which they are not. Within the 2000-2001 school year, more than 700,000 students within the American public school system were categorized as having either a language impediment or a speech impediment. Ironically, all three speech impediments contain the troubled letter within them.

The word rhotacism comes from the New Latin rhotacism meaning peculiar or excessive use of [r]. The Latin word came from Ancient Greek word rhōtakismós which means to incorrectly use “rho” which is the equivalent of the Greek R. For language nerds, here’s a really great explanation of how the word came into being.

How does rhotacism work in different languages?

Rhotacism is, in theory , more common among people whose native language has a trilled R. For example, in Spanish the “rr” is a trilled R. Other languages with a trilled R include Bulgarian, Hungarian, Arabic, Finnish, Romanian, Indonesian, Russian , Italian, and most Swedish speakers. Some people might mock Asians, specifically Chinese, for not being able to pronounce the English word “broccoli” correctly- rather pronouncing it “browccoli”. This isn’t due to a rhotacism, however. It’s actually due to the fact that Mandarin (Chinese) words can have an “r” sound in the beginning of a word, but not in the middle or end of a word. This leads them to have issues in their phonotactics and creates an inability to pronounce the English “R” in the middle of words.

The leader of Hezbollah, Hasan Nasrallah, is a Lebanese leader and is mocked for his rhotacism when he says, “ Amwīka ” and “ Iswā’īl ” for the Arabic Amrīka (America), and Isrā’īl (Israel). He is a native Arabic speaker- a language which has the trilled R. Notice how he puts a W sound in those two words where the R sound usually is.

Symptoms of rhotacism

• Some people try to hide their impediment by avoiding words with R ’s in them.
• An overall inability to say R sounds
• Using trilled R’s or guttural R’s (such as the French R) when trying to pronounce the regular English R.

Rhotacism as a speech impediment

Using a strict classification, only about 5%-10% of the human population speaks in a completely normal way. Everyone else suffers from some type of speech disorder or another. For children of any language, the R sounds are usually the hardest to master and often end up being the last ones a child learns. That’s why baby talk if you think about it, doesn’t really use explicit or strong R sounds. In English, rhotacism often comes off as a W sound which is why “Roger Rabbit” sounds like “Woger Wabbit”. R is often more difficult because a child has to learn the different combination of the /r/ sounds, not just the letter itself, unlike other letters. For example, when it comes before and after vowel sounds. The combination of a vowel with the /r/ sound is called a phenome and in English, there are eight combinations of these:

–        The prevocalic R , such as “rain”

–        The RL , such as “girl”

–        The IRE, such as “tire”

–        The AR, such as “car”

–        The EAR , “such as “beer”

–        The OR , such as “seashore”

–        The ER , such as “butter”

–        The AIR , such as “software”

A speech impediment is a speech disorder , not a language disorder . Speech disorders are problems in being able to produce the sounds of speech whereas language disorders are problems with understanding and/or being able to use words. Language disorders, unlike speech disorders, have nothing to do with speech production.

Often what happens is that the person speaking isn’t tensing their tongue enough, or not moving their tongue correctly (up and backward depending on the dialect) which makes the W or “uh” sound come out. It may also be that the person is moving their lips instead of their tongue.

Examples of rhotacism

• Barry Kripke from the TV show The Big Bang Theory has both rhotacism and lambdacism- meaning he has issues pronouncing both his R ’s and his L ’s.
• The most famous of rhotacism would be Elmer Fudd from Looney Tunes . He pronounces the word “rabbit” [ˈɹ̠ʷæbɪ̈t] as “wabbit” [ˈwæbɪ̈t]
• In Monty Python’s Life of Brian , the 1979 film’s character Pilate suffers from rhotacism. In the film, people mock him for his inability to be understood easily.

Here’s a video with a woman who suffers from rhotacism. She explains how difficult it can be to have the speech impediment.

Causes of rhotacism

For many people, the causes of rhotacism are relatively unknown-, especially in adults. However, scientists theorize that the biggest cause is that the person grew up in an environment where they heard R ’s in a weird way, the shape of their mouths are different than normal, or their tongues and lips never learned how to produce the letter. In children, this could happen because the parents or adults around think the way the child talks (using baby talk) is cute and the child never actually learns how to produce it.

For one internet forum user, it has to do with how they learned the language , “I speak various languages, I pronounce the “R” normal in Dutch, French, and Spanish, but I have a rhotacism when speaking English. It’s the way I learnt it.”

For other people, speech issues are a secondary condition to an already existing, serious condition. Physically, it would be a cleft lip or a cleft palate. Neurologically, it could be a condition such as cerebral palsy. It may also be a tongue tie . Almost everyone has a stretch of skin that runs along the bottom of their tongue. If that skin is too tight and reaches the tip of the tongue, it can make pronouncing (and learning how to pronounce) R ’s and L ’s difficult. If the tongue tie isn’t fixed early on, it can be incredibly difficult to fix and learn how to pronounce later.

How the brain affects rhotacism

The brain affects rhotacism only for those who suffer from it not due to a physical impediment (such as a cleft palate). For some, this could happen because the brain doesn’t have the phonemic awareness and never actually learned what the letter R is supposed to sound like. This is common with kids whose parents spoke to them in “baby talk” and encouraged the child’s baby talk, too. This kind of behavior only strengthens a child’s inner concept that / R / is pronounced like “w” or “uh”.

Another reason could be that the brain connections simply don’t allow the lips or mouth to move in the way they need to in order to pronounce the R . This inability has little to do with physical incapabilities and more to do with mental ones. Some people with rhotacism have an issue with their oral-motor skills which means that there isn’t sufficient communication in the parts of the brain responsible for speech production.

Treatment for rhotacism

Is rhotacism curable.

It can have negative social effects- especially among younger children, such as bullying, which lowers self-esteem and can have a lasting effect. However, if the impediment is caught early enough on and is treated rather quickly, there is a good overall prognosis meaning it’s curable.

        However, some people never end up being able to properly pronounce that R and they end up substituting other sounds, such as the velar approximant (like w sounds) , the uvular approximant (also known as the “French R ”), and the uvular trill ( like the trilled R in Spanish).

How to fix rhotacism

Rhotacism is fixed by speech therapy . Before anything else, there needs to be an assessment from a Speech Language Pathologist (SLP) who will help decide if the problem can be fixed. If a child is involved, the SLP would predict if the child can outgrow the problem or not. After the diagnosis, a speech therapist will work with the person who suffers from the speech impediment by possibly having weekly visits with some homework and practice instructions. Therapy happens in spouts- a period of a few weeks and a break. There is a follow-up to see if there has been an improvement in pronunciation. In the U.S., children who are in school and have a speech disorder are placed in a special education program. Most school districts provide these children with speech therapy during school hours.

Another option, often used alongside speech therapy, is using a speech therapy hand-held tool that helps isolate the sound being pronounced badly and gives an image of the proper tongue placement to enable better pronunciation.

One study tested a handheld tactical tool (known as Speech Buddies) and the traditional speech therapy methods. The study found that students who used the hand-held tool (alongside speech therapy) improved 33% faster than those who used only the traditional speech therapy methods.
