Selected characteristics of disfluent conversational utterances with and without disfluency clusters were examined in 14 children who stutter (CWS) and 14 children who do not stutter (CWNS). For CWS, utterances with disfluency clusters contained significantly more syllables and clausal constituents than disfluent utterances without clusters, which, in turn, contained significantly more syllables, clauses, and clausal constituents than fluent utterances. For both groups of children, disfluency clusters coincided significantly more often with utterance or clause onset than they did with grammatical constituents located elsewhere within an utterance. CWNS produced a significantly greater percentage of disfluency clusters that contained grammatical revision than did CWS. No significant between-group differences were observed in terms of the number of syllables, clauses, or clausal constituents within cluster-inclusive utterances. Findings are taken to suggest that disfluency clusters are typically produced within the most complex linguistic contexts and that they reflect the effects of producing multiple syntactic constituents within an utterance.
在14名口吃儿童（CWS）和14名非口吃儿童（CWNS）中，研究了带有和不带有不流畅集群的不流畅对话话语的选定特征。对于口吃儿童，带有不流畅集群的话语比没有集群的不流畅话语包含明显更多的音节和从句成分，而没有集群的不流畅话语又比流畅话语包含明显更多的音节、从句和从句成分。对于两组儿童，不流畅集群与话语或从句起始的重合频率明显高于与话语中其他位置的语法成分的重合频率。非口吃儿童产生的包含语法修正的不流畅集群的百分比明显高于口吃儿童。在包含集群的话语中的音节、从句或从句成分数量方面，未观察到显著的组间差异。研究结果表明，不流畅集群通常在最复杂的语言环境中产生，并且它们反映了在话语中生成多个句法成分的影响。
