| Abstract: | Effects of repeated oral readings on durational and fundamental frequency characteristics and number and kinds of reading errors were investigated in 11 stutterers and 11 sex- +and age-matched nonstutterers. Computer analysis of durational and fundamental frequency characteristics of the first and sixth readings demonstrated statistically significant differences in mean pause duration, speaking-time ratio, and total speaking time between the stutterers and the nonstutterers. In addition, there were significant differences in mean utterance duration and number of utterances (and pauses) between the first and sixth readings. Finally, correlational analyses indicated variable performance in the stutterers whereas the nonstutterers demonstrated highly consistent performance between the first and sixth readings. Results of reading error analysis showed more and different types of reading errors by the stutterers in comparison to the nonstutterers although both groups demonstrated a reduction in reading errors from the first to the sixth readings. |
