本研究的目的是比较口吃者和非口吃者在两种不同的言语语境中的流利性。22名成年口吃者在1岁内与22名非口吃者相匹配。对受试者连续五次流畅地产出一个简单的孤立短语和一个从口语阅读段落中提取的短语进行了语谱分析。流利的声音开始时间（VOT），元音，辅音和总短语持续时间的措施计算从每个短语的五次重复。从孤立的短语中，总共有五个流利的持续时间测量（即，一个VOT、两个元音、一个辅音和一个短语持续时间）。对于取自口语阅读段落的短语，获得了六个流畅性测量（即，一个VOT、三个元音、一个辅音和一个短语持续时间）。结果表明，在孤立阶段条件下进行的五次测量中，只有一次在两组之间存在显著差异。从口头阅读条件下采取的短语中获得的六项措施中有三项显示出显着的组间差异。两组的任何依赖性测量结果均与重复任何一个短语无关。这些发现表明，用于获得口吃者流利性声学测量的言语任务的长度和复杂性在发现两组流利性之间的差异方面发挥着重要作用。
The purpose of this study was to compare stutterers' and nonstutterers' fluency during multiple productions of two dissimilar speech contexts. Twenty-two adult stutterers were matched within 1 year of age to 22 nonstutterers. Spectrographic analyses were performed on subjects' five consecutively fluent productions of a simple isolated phrase and a phrase extracted from an oral reading passage. Measures of fluent voice onset time (VOT), and vowel, consonant, and total phrase durations were calculated from the five repetitions of each phrase. From the isolated phrase, there were a total of five fluent durational measures (i.e., one VOT, two vowel, one consonant, & one phrase duration). For the phrase taken from the oral reading passage, six fluent measures were obtained (i.e., one VOT, three vowel, one consonant, & one phrase duration). Results demonstrated that only one of the five measurements taken during the isolated phrase condition was significantly different between the groups. Three of the six measures obtained from the phrase taken from the oral reading condition revealed significant between-group differences. No group differences were associated with the repetitions of either phrase for any of the dependent measures for both groups. These findings suggest that the length and complexity of the speech tasks used to obtain acoustic measures of stutterers' fluency play an important role in the discovery of differences between the fluency of the two groups.
