Measurements of the difference in average speaking rate, average number of pauses, average pause duration, and average duration of the vowels that received primary stress were obtained from the speech samples of 35 stutterers and 35 nonstutterers. The samples had been screened to ensure that they contained no instances of overt stuttering, audible respirations, or inappropriate voicing. The measurements were used as the predictors in multiple linear regression analyses. The criterion variable was the average percent-correct discriminations of 40 subjects who listened to the samples in pairs and indicated which member of each pair was the stutterer. The results showed that the difference in speaking rate combined with either pause measure accounted for approximately 70% of the variance in the listeners' responses. The findings indicate that speaking rate and pauses are potential perceptual cues for listeners attempting to discriminate the speech of stutterers from that of nonstutterers.
