Summary

According to studies, speech disorders with unknown causes (idiopathic) affect approximately 5% of the population at some point in their life. Some of these disorders like, stuttering and cluttering, are known for being detected early, during speech development.

Stuttering is characterized by sound and syllable repetitions and consonant/vowel prolongations. When stuttering is moderate to severe, it can interfere with a person's job and social activities.

Speech articulation disorders are characterized by omissions, or substitutions of speech sounds. The speech of a person who clutters is often difficult to understand. People are often unaware of the errors they make when speaking causing treatment of the condition to be very difficult.

The purpose of this research is to study an extended family whose members exhibit a pure form of speech articulation disorders

In addition, the study will use data and information gathered from the study and use it to develop guidelines (criteria) for defining and differentiating patients with speech disorders.
