Fluency Disorders (disfluencies)
Fluency disorders (disfluencies) refer to excessive breaks or disruptions in the normal flow of speech.
Stuttering is characterized by repetitions of words or parts of words, prolongations of speech sounds, complete stoppages or blocks in speech, and interjections such as �um� or �like.�
Cluttering is characterized by a speech delivery rate that is abnormally rapid and/or irregular (talking too fast or in spurts) and disfluencies that are frequent but not judged to be stuttering. Cluttering seems to result from disorganized speech planning and is often accompanied by language or phonological errors and attention deficits.
