Clinical diagnostic procedures to distinguish stuttering from non-stuttering individuals partially rely on the observation of characteristics of stuttered words or syllables. The purpose of this study was to examine the sensitivity and specificity of such a procedure, and to describe the observed characteristics of stuttered words. Methods involved the recording of the frequency, duration, and physical tension of stuttered words in conversational speech samples (total 43, 100 words) and in an oral reading task (total 43, 100 words). In this manner, 351 native Dutch speaking people, aged 8-53, who stutter were compared to a group of non-stuttering peers (n = 80). Findings suggest that applying a criterion of 3% stuttered words in conversational speech makes it possible to distinguish stuttering from non-stuttering individuals with high sensitivity (.9345) and perfect specificity (1.0000). Frequency, duration, and physical tension accompanying stuttered words are described for the group of stuttering participants, and these characteristics were compared to the group of non-stuttering speakers.
区分口吃者与非口吃者的临床诊断程序部分依赖于对口吃单词或音节特征的观察。本研究的目的是检验该程序的敏感性和特异性，并描述观察到的口吃单词的特征。研究方法包括记录对话语音样本（共43个，100个单词）和口头阅读任务（共43个，100个单词）中口吃单词的频率、持续时间和身体紧张程度。通过这种方式，将351名年龄在8至53岁之间、母语为荷兰语的口吃者与一组非口吃同龄人（n = 80）进行了比较。研究结果表明，在对话语音中应用3%的口吃单词标准，可以以高敏感性（.9345）和完美特异性（1.0000）区分口吃者与非口吃者。对口吃参与者组的口吃单词的频率、持续时间和身体紧张程度进行了描述，并将这些特征与非口吃者组进行了比较。
