Speech disorders - children

A speech disorder is a condition in which a person has problems creating or forming the speech sounds needed to communicate with others.

Three common speech disorders are:

• Articulation disorders
• Disfluency
• Voice disorders

Speech disorders are different from language disorders in children , such as:

• Getting their meaning or message across to others
• Understanding the message coming from others

Causes

Speech is one of the main ways in which we communicate with those around us. It develops naturally, along with other signs of normal growth and development .

Disfluencies are disorders in which a person repeats a sound, word, or phrase. Stuttering may be the most serious disfluency.

Articulation disorders may have no clear cause. They may also occur in other family members. Other causes include:

• Problems or changes in the structure or shape of the muscles and bones used to make speech sounds. These changes may include cleft palate and tooth problems.

  Cleft palate

  Cleft lip and palate are birth defects that affect the upper lip and the roof of the mouth.

• Damage to parts of the brain or the nerves (such as from cerebral palsy ) that control how the muscles work together to create speech.

Voice disorders are caused by problems when air passes from the lungs, through the vocal cords, and then through the throat, nose, mouth, and lips. A voice disorder may be due to:

• Acid from the stomach moving upward ( GERD )

• Cleft palate or other problems with the palate
• Conditions that damage the nerves that supply the muscles of the vocal cords

  Conditions that damage the nerves

  Laryngeal nerve damage is injury to one or both of the nerves that are attached to the voice box.

• Laryngeal webs or clefts (a birth defect in which a thin layer of tissue is between the vocal cords)
• Noncancerous growths (polyps, nodules, cysts, granulomas, papillomas, or ulcers) on the vocal cords
• Overuse of the vocal cords from screaming, constantly clearing the throat, or singing

Symptoms

DISFLUENCY

Stuttering is the most common type of disfluency.

Symptoms of disfluency can include:

• Repetition of sounds, words, or parts of words or phrases after age 4 (I want...I want my doll. I...I see you.)
• Putting in (interjecting) extra sounds or words (We went to the...uh...store.)
• Making words longer (I am Boooobbby Jones.)
• Pausing during a sentence or words, often with the lips together
• Tension in the voice or sounds
• Frustration with attempts to communicate
• Head jerking while talking
• Eye blinking while talking
• Embarrassment with speech

ARTICULATION DISORDER

• Sounds may be distorted (changed)
• Sounds (most often consonants) will be substituted, left off, added, or changed
• Errors may make it hard for people to understand the person (only family members may be able to understand a child)

VOICE DISORDERS

• Hoarseness or raspiness to the voice
• Voice may break in or out
• Pitch of the voice may change suddenly
• Voice may be too loud or too soft
• Person may run out of air during a sentence
• Speech may sound odd because too much air is escaping through the hose (hypernasality) or too little air is coming out through the nose (hyponasality)

Exams and Tests

The following tests can help diagnose speech disorders:

• Denver Articulation Screening Examination
• Early Language Milestone Scale
• Denver II test
• Peabody Picture Test Revised

A hearing test may also be done.

Treatment

Milder forms of speech disorders may disappear on their own.

Speech therapy may help with more severe symptoms or speech problems that do not improve.

In therapy, the child will learn how to create certain sounds.

Outlook (Prognosis)

Outlook depends on the cause of the disorder. Speech can often be improved with speech therapy. Early treatment is likely to have better results.

Possible Complications

Speech disorders may lead to psychosocial problems associated with ineffective communication.

When to Contact a Medical Professional

Call your health care provider if:

• Your child's speech is not developing according to normal milestones
• You think your child is in a high-risk group
• Your child is showing signs of a speech disorder

Prevention

Intellectual disability and hearing loss make children more likely to develop speech disorders. At-risk infants should be referred to an audiologist for a hearing test. Hearing and speech therapy can then be started, if necessary.

As young children begin to speak, some disfluency is common. Children lack a large vocabulary and have difficulty expressing themselves. This results in broken speech. If you place excessive attention on the disfluency, a stuttering pattern may develop. The best way to prevent stuttering, therefore, is to avoid paying too much attention to the disfluency.
