Acoustical durations of stutter- and disfluency-free speech segments from Readings #1 and #5 in an adaptation series were measured in 4 adapting, 4 nonadapting, and 4 nonstuttering subjects. The segment durations measured were intervocalic interval, stop-gap, voice onset time, and vowel duration. No clear trends in the change of acoustical durations from Reading #1 to Reading #5 distinguished the adapting, nonadapting, or nonstuttering subjects. Moreover, on the basis of speech naturalness judgements, listeners did not differentiate the Reading #1 and #5 phrase segments of subjects with high adaptation versus those with low adaptation scores. From these findings and related literature, adaptation of stuttering, as well as other fluency-inducing conditions, are viewed as circumstances that reduce demands upon central motor-linguistic processes.
在一个适应系列中，对4名正在适应的、4名未适应的和4名不口吃的受试者，测量了读物1和读物5中无口吃和流畅性言语片段的声学时长。所测量的片段时长包括元音间间隔、塞音间隙、嗓音起始时间和元音时长。从读物1到读物5，声学时长的变化没有明显趋势能区分正在适应的、未适应的或不口吃的受试者。此外，基于言语自然度判断，听众无法区分适应得分高的受试者和适应得分低的受试者的读物1和读物5的短语片段。根据这些发现和相关文献，口吃的适应以及其他诱导流畅性的条件，被视为减少对中枢运动语言过程需求的情况。
