The aims of this study were to provide a perceptual speech 'profile' for Cantonese speakers with hypokinetic dysarthria, to examine the reliability of non-expert listeners in perceptual judgements of dysarthric speech, and to investigate cross-language differences in profiles of hypokinetic dysarthria. Participants included 19 speakers with Parkinson's disease and 10 speech-language pathologists who served as listeners. Listeners rated 21 speech dimensions, using seven-point interval scales. Mean intralistener agreement was 94.52% and mean interlistener reliability was 0.88 (Cronbach's alpha). Mean scale values (MSV) for each dimension ranged from 3.37 to 1.36. The perceptual profile of Cantonese hypokinetic dysarthria was largely similar to profiles for English and Japanese speakers; notable differences are discussed. Possible reasons for the relatively high reliability obtained are presented.
本研究的目的是为患有运动减退型构音障碍的粤语使用者提供一个感知语音“概况”，检验非专业听众对构音障碍语音进行感知判断的可靠性，并调查运动减退型构音障碍概况中的跨语言差异。参与者包括19名帕金森病患者和10名言语语言病理学家作为听众。听众使用七点间隔量表对21个语音维度进行评分。听众内部平均一致性为94.52%，听众间平均信度为0.88（克朗巴赫α系数）。每个维度的平均量表值（MSV）范围为3.37至1.36。粤语运动减退型构音障碍的感知概况与英语和日语使用者的概况基本相似；文中讨论了显著差异。还提出了获得相对较高信度的可能原因。
