Title

Variance Of Central Timing Of Voiced And Voiceless Periods Among Stutterers And Nonstutterers

Abstract

The finding of distinctively greater temporal variability among stutterers is consistent with the hypothesis that the cause of their speech disruption is related to the excessive variability in their speech motor system. This hypothesis, would lead to expect that the stutterers' temporal variability would be reduced when they lower their speech rate, a condition known to reduce the frequency of stuttering. However, crucial for the variability hypothesis is the contention that the excessive variability deemed to be causative stems from the central timing mechanism of the speech production system. To find this component of variability, that which is due to speech rate variations and that due to peripheral mechanisms must be separated from the observed total variability in segment durations. A procedure to achieve this is outlined. The application of this procedure showed a normalization of the stutterers' variability during moderate slowing of speech. © 1995.
