The hypothesis that stuttering and nonstuttering adults have fewer disfluencies during voiced-voiced phoneme-to-phoneme phonatory transitions than during voiced-voiceless, voiceless-voiced, or voiceless-voiceless transitions was investigated. The speech of 11 adult stutterers and a matched group of nonstutterers was analyzed according to the occurrence of disfluencies during the above categories of phonatory transtions. Each subject's speech was recorded individually while reading several passages. The percentage of disfluencies varied significantly (p less than 0.001) across the four phonatory transition categories for both groups of subjects. Both stutterers and nonstutterers demonstrated a lower percentage of disfluencies during voiced-voiced transitions than during voiced-voiceless, voiceless-voiced, and voiceless-voiceless phonatory transitions. Furthermore, both groups of subjects demonstrated a similar distribution of disfluencies across the four phonatory transitions categories. An inability to successfully complete phoneme-to-phoneme phonatory transitions does not appear to fully explain the pattern of disfluencies for stuttering or nonstuttering adults.
对口吃和非口吃成年人而言，浊音到浊音的音素间发声过渡时的不流畅性比浊音到清音、清音到浊音或清音到清音的过渡时更少，这一假设得到了研究。根据上述发声过渡类别中不流畅性的出现情况，对11名成年口吃者和一组匹配的非口吃者的言语进行了分析。每个受试者在朗读几篇文章时单独录音。两组受试者在四种发声过渡类别中的不流畅性百分比差异显著（p小于0.001）。口吃者和非口吃者在浊音到浊音的过渡中表现出的不流畅性百分比均低于浊音到清音、清音到浊音和清音到清音的发声过渡。此外，两组受试者在四种发声过渡类别中的不流畅性分布相似。无法成功完成音素间发声过渡似乎并不能完全解释口吃或非口吃成年人的不流畅性模式。
