| Abstract: | Longer VOT and segment durations apparently characterize the contrived responses of school-age stutterers examined under laboratory conditions. Thus, these variables may reflect basic disparities between the speech production abilities of stutterers and normal speakers. To better explore this possibility, VOT and segment durations were assessed in five nonstutterers who were closely matched with five preschool stutterers who had been diagnosed and tested in the experiment within six months of parental concern about fluency development. Target words were measured in isolation, in elicited sentences, and conversation. Results revealed significantly slower VOT and longer segment durations in the young stuttering members of the pairs of speakers. The stutterers were also more variable in their management of these same two aspects of motor speech timing control. |
