A few clinical reports and empirical studies have suggested a possible deficit in the perception of speech in individuals with Parkinson's disease. In this paper, these studies are reviewed in an attempt to support clinical anecdotal observations by relevant empirical research findings. The combined evidence suggests a possible deficit in patients' perception of their own speech loudness. Other research studies on the perception of speech in this population were reviewed, in a broader scope of the perception of emotional prosody. These studies confirm that Parkinson's disease specifically impairs patients' perception of verbal emotions. However, explanations of the nature and causes of this perceptual deficit are still limited. Future research directions are suggested.
一些临床报告和实证研究表明，帕金森病患者的言语感知可能存在缺陷。本文回顾了这些研究，旨在通过相关实证研究结果支持临床轶事观察。综合证据表明，患者对自己言语响度的感知可能存在缺陷。其他关于该人群言语感知的研究也进行了回顾，范围更广，涉及情感韵律的感知。这些研究证实，帕金森病特别影响患者对言语情绪的感知。然而，对这种感知缺陷的性质和原因的解释仍然有限。提出了未来的研究方向。
