本研究调查了12名帕金森氏病(PD)伴发构音障碍的说话人的发音内和发音对句子清晰度影响的声学基础。此外，还对12名健康对照进行了声学测量，以与患有帕金森病的说话者进行比较。演讲者用他们典型的讲话风格朗读句子。测量语速、清晰度、基频、声压级和F2四分位数范围(F2 IQR)。一组听者使用计算机化的视觉模拟标尺来判断句子的可理解性。对于患有帕金森病的个别说话者，确定了清晰度判断和声学测量之间的关系。声学测量之间的关系也被量化。虽然注意到了相当大的变异性，但发音率、基频和F2 IQR最常与说话人内部句子清晰度的差异有关。结果表明，在解释群体分析的结果时，应考虑到帕金森病患者说话者的多样性。
This study investigated the acoustic basis of within-speaker, across-utterance variation in sentence intelligibility for 12 speakers with dysarthria secondary to Parkinson’s disease (PD). Acoustic measures were also obtained for 12 healthy controls for comparison to speakers with PD. Speakers read sentences using their typical speech style. Acoustic measures of speech rate, articulatory rate, fundamental frequency, sound pressure level and F2 interquartile range (F2 IQR) were obtained. A group of listeners judged sentence intelligibility using a computerized visual-analog scale. Relationships between judgments of intelligibility and acoustic measures were determined for individual speakers with PD. Relationships among acoustic measures were also quantified. Although considerable variability was noted, articulatory rate, fundamental frequency and F2 IQR were most frequently associated with within-speaker variation in sentence intelligibility. Results suggest that diversity among speakers with PD should be considered when interpreting results from group analyses.
