In two experiments, various aspects of prosody in adult male stutterers and nonstutterers were studied. The results showed that stutterers did not speak with a generally reduced pitch pattern, they were able to place sentence accent correctly but had difficulty executing this prosodic feature, stuttering episodes were located mainly on stressed syllables, a fixed timing pattern of speech enhanced fluency, and the intervals between stressed syllables were more variable in the speech of stutterers, even in symptom-free passages, than in the speech of nonstutterers. Results support the conclusion that stuttering, seen on the symptomatic level of disfluencies produced, is a prosodic disturbance.
在两项实验中，对成年男性口吃者和非口吃者韵律的各个方面进行了研究。结果表明，口吃者并非普遍采用降低的音高模式说话，他们能够正确地放置句子重音，但在执行这种韵律特征时存在困难，口吃发作主要出现在重读音节上，固定的言语节奏模式可提高流畅性，并且与非口吃者的言语相比，口吃者的言语中重读音节之间的间隔变化更大，即使在无症状的段落中也是如此。结果支持这样的结论，即从产生不流畅的症状层面来看，口吃是一种韵律障碍。
