Relative Timing Of Speech Motor Events At Utterance Invitation In Persons Who Do And Do Not Stutter, Bryan Thomas Brown

Masters Theses

Speech production is a highly complex speech motor activity that presumably requires a high degree of coordination between articulatory, respiratory and phonatory subsystems. Stuttering may be caused by breakdowns in speech motor coordination. The current study attempted to evaluate timing relationship between these systems at speech initiation in the perceptually fluent speech of people who do and do not stutter. To study this, tongue blade speed histories, respiratory transitions from inspiratory to expiratory gestures, and acoustic events at the initiation of perceptually fluent speech in persons who stutter and normally fluent speakers were analyzed in relative time. To identify the …
