The purpose of this study was to measure the duration of sound prolongations and sound/syllable repetitions (stutterings) in the conversational speech of school-age children who stutter. The relationships between duration and (a) frequency and type of speech disfluency, (b) number and rate of repeated units per instance of sound/syllable repetition, (c) overall speech rate, and (d) articulatory rate were also examined. Results indicated that for the children in this study the average duration of stuttering was approximately three-quarters of a second, and was not significantly correlated with age, length of post-onset interval, or frequency of speech disfluency. In addition, findings can be taken to suggest that part of the clinical significance of stuttering duration for children who stutter might lie in its relationship to the amount of sound prolongations these children produce, as well as their articulatory rate during fluent speech.
本研究的目的是测量口吃学龄儿童对话言语中声音延长和声音/音节重复（口吃）的持续时间。同时还研究了持续时间与以下因素之间的关系：（a）言语不流畅的频率和类型；（b）每次声音/音节重复的重复单元数量和速率；（c）整体言语速率；（d）发音速率。结果表明，在本研究中的儿童，口吃的平均持续时间约为四分之三秒，且与年龄、发病后间隔时间长短或言语不流畅频率无显著相关性。此外，研究结果表明，口吃持续时间对口吃儿童的部分临床意义可能在于其与这些儿童产生的声音延长量以及流利言语期间的发音速率之间的关系。
