The present study was concerned with the development and evaluation of a scale of speech naturalness. Speech samples were recorded of the typical speech of 10 stutterers, 10 stutterers speaking without stuttering under 250-ms delayed auditory feedback (DAF), and 10 nonstutterers speaking normally. Using a 9-point scale, 30 unsophisticated listeners judged how natural the speech sounded in each sample. Results indicated that the stutterer samples were judged as sounding significantly more unnatural than the nonstutterer samples, and the DAF stutter-free samples were judged as sounding significantly more unnatural than the nonstutterer samples. The stutterer and DAF stutter-free samples were not judged as sounding significantly different in terms of speech naturalness. Interrater reliability, interrater agreement, and rater consistency for judging speech naturalness were all satisfactory.
本研究关注言语自然度量表的开发与评估。记录了10名口吃者的典型言语样本、10名口吃者在250毫秒延迟听觉反馈（DAF）条件下流畅说话的样本以及10名正常说话的非口吃者的样本。30名未经专业训练的听众使用9分制量表判断每个样本中言语听起来的自然程度。结果表明，口吃者的样本被判定比非口吃者的样本听起来明显更不自然，DAF条件下无口吃的样本被判定比非口吃者的样本听起来明显更不自然。在言语自然度方面，口吃者和DAF条件下无口吃的样本被判定没有显著差异。判断言语自然度的评分者间信度、评分者间一致性和评分者一致性均令人满意。
