Abstract:
The speech of nine adult stutterers was analyzed acoustically prior to and at the termination of a modified Van Riperian procedure to determine if therapy produced discernable changes in their post-therapy fluent speech. The findings indicate that stuttering frequency decreased significantly and reading rate decreased by a statistically insignificant amount during the course of therapy. Vowel duration and the occurrence of voicing during the stop consonant production increased significantly. These findings support the hypothesis that stuttering therapy can affect more than the fluency and rate characteristics of the stutterer's posttherapy speech.
