This study investigated the effect of auditory feedback alterations on stuttering frequency of 10 adults. At high speech rates, stuttering frequency was significantly reduced under delayed auditory feedback, frequency altered feedback, and a combination. There were no significant differences among the altered feedback conditions. (Author/SW)

Models of stuttering and delayed auditory feedback propose that, in these conditions, the rhythmic structure of fluent speech prespecifing the intervals between vowels of stressed syllables is lacking and that auditory perception of vowels of stressed syllables is predicted incorrectly. A model regarding onset of stuttering in children is also…

A computer was used to help a man who stuttered severely most of his 37 years. The criterion based treatment used a specifically designed program (Speech Flow Acquisition Program) to train him to speak smoothly. (SEW)

A series of single-subject experiments evaluated the effects of frequency-altered auditory feedback (FAF) on the speech performance of four adult males who stutter. FAF was compared with normal auditory feedback in oral reading and spontaneous speech. Results indicate no consistencies across subjects in responses to FAF. (Author/CR)
