Three questions were addressed in this study: (a) Do mothers of stuttering children talk faster than mothers of nonstuttering children, (b) do stuttering children talk faster than nonstuttering children, and (c) is there a relationship between child's rate of speech and mother's rate of speech in dyadic conversation? Twelve nonstuttering preschool boys and their mothers were matched with 12 stutterers and their mothers. Ten min of free-play interaction between alternated mother-child dyads were video recorded. Speech rates, defined as syllables per second in fluent utterances, were calculated. Results demonstrated that mothers of stutterers talked significantly faster to all children. Stutterers spoke slower than nonstutterers, and severe stutterers spoke slower than moderate stutterers. A correlational analysis revealed that the more the child stuttered, the slower he talked during fluent speech. Further, the slower the child talked during fluent speech, the faster the mother interacting with him talked. The results reveal an interactive and complex relationship between mother and child speech rates. The interpretation of results relating to child speech rates was complicated by post hoc analyses revealing a significant relationship between speech rates and utterance length.
（a）口吃儿童的母亲说话速度是否比非口吃儿童的母亲快，（b）口吃儿童说话速度是否比非口吃儿童快，以及（c）在二元对话中，儿童的语速与母亲的语速之间是否存在关系？12名非口吃学龄前男孩及其母亲与12名口吃者及其母亲进行了匹配。对交替的母子二元组之间10分钟的自由玩耍互动进行了视频记录。计算了语速，即流畅话语中的每秒音节数。结果表明，口吃者的母亲与所有儿童交谈时语速明显更快。口吃者说话比非口吃者慢，严重口吃者比中度口吃者说话慢。相关分析表明，儿童口吃越严重，在流畅言语中说话就越慢。此外，儿童在流畅言语中说话越慢，与他互动的母亲说话就越快。结果揭示了母子语速之间的一种互动且复杂的关系。事后分析显示语速与话语长度之间存在显著关系，这使得对口吃儿童语速相关结果的解释变得复杂。
