目的：鉴于语音自然度的功能和社会康复的结果的潜在意义，本研究的目的是研究的效果，听者的感知的Parkinson's disease（PD）的个人语音自然度和可懂度的Parkinson's disease（PD）。方法：两个短的话语提取的独白样本的16个扬声器与PD和5个年龄匹配的成年人没有PD。16名听众评价这些刺激的palletitch，语音自然度和可懂度使用的视觉sort and rate method.Results：天真的听众可以可靠地判断palletitch，语音自然度，和可懂度与最小的熟悉。虽然pklitch和语音清晰度只有中度相关，pklitch和语音自然度高度相关。结论：大量的关注，目前正在支付的改善声乐响度，从而在PD语音清晰度。我们的研究结果表明，韵律的特点，如palletitch应探讨这种治疗构音障碍的帕金森氏症。发展这种韵律治疗可以提高语音自然度，从而提高生活质量。
Purpose: Given the potential significance of speech naturalness to functional and social rehabilitation outcomes, the objective of this study was to examine the effect of listener perceptions of monopitch on speech naturalness and intelligibility in individuals with Parkinson's disease (PD).Method: Two short utterances were extracted from monologue samples of 16 speakers with PD and 5 age-matched adults without PD. Sixteen listeners evaluated these stimuli for monopitch, speech naturalness and intelligibility using the visual sort and rate method.Results: Naive listeners can reliably judge monopitch, speech naturalness, and intelligibility with minimal familiarization. While monopitch and speech intelligibility were only moderately correlated, monopitch and speech naturalness were highly correlated.Conclusions: A great deal of attention is currently being paid to improvement of vocal loudness and thus speech intelligibility in PD. Our findings suggest that prosodic characteristics such as monopitch should be explored as adjuncts to this treatment of dysarthria in PD. Development of such prosodic treatments may enhance speech naturalness and thus improve quality of life.
