The relationship of stuttering severity and treatment length to temporal measures of stutterers' perceptually fluent speech.
The purpose of this study was to investigate the relationship between stuttering severity and treatment length to temporal measures of stutterers' perceptually fluent speech. Seventeen adult stutterers (4 mild, 8 moderate, and 5 severe) were divided into two treatment categories. One group with limited exposure to treatment (n = 7) consisted of stutterers who had completed 0-10 hr of treatment. Another group with an extensive period of treatment (n = 10) consisted of stutterers who had completed 47-212 hr of treatment. All subjects were asked to repeat a simple phrase and read a prose passage. Spectrographic measures of the stutterers' voice onset times, vowel, consonant, and phrase durations were obtained from perceptibly fluent productions of the isolated phrase and from a phrase extracted from the oral reading. Results showed that there were no significant differences among stuttering severity groups or the two groups with different lengths of treatment. These results suggest that changes in temporal measures of stutterers' fluency might occur through the process of treatment, but those changes are not related to stuttering severity or length of treatment.
