This study examines the impact of Parkinson's disease (PD) on communicative efficiency conveyed through prosody. A new assessment method for evaluating productive prosodic skills in Dutch speaking dysarthric patients was devised and tested on 36 individuals (18 controls, 18 PD patients). Three professional listeners judged the intended meanings in four communicative functions of Dutch prosody: Boundary Marking, Focus, Sentence Typing, and Emotional Prosody. Each function was tested through reading and imitation. Interrater agreement was calculated. Results indicated that healthy speakers, compared to PD patients, performed significantly better on imitation of Boundary Marking, Focus, and Sentence Typing. PD patients with a moderate or severe dysarthria performed significantly worse on imitation of Focus than on reading of Focus. No significant differences were found for Emotional Prosody. Judges agreed well on all tasks except Emotional Prosody. Future research will focus on elaborating the assessment and on developing a therapy programme paralleling the assessment.
这项研究考察了帕金森病（PD）对通过韵律传达的交际效率的影响。为了评估讲荷兰语的构音障碍患者的生产性韵律技能，设计了一种新的评估方法，并在 36 名个体（18 名对照组，18 名 PD 患者）中进行了测试。三位专业听众根据荷兰语韵律的四个交际功能（边界标记、焦点、句子类型和情感韵律）来判断意图。每个功能都通过阅读和模仿进行测试。计算了评分者间的一致性。结果表明，与 PD 患者相比，健康说话者在模仿边界标记、焦点和句子类型方面表现明显更好。中度或重度构音障碍的 PD 患者在模仿焦点方面的表现明显差于阅读焦点。在情感韵律方面未发现显著差异。除了情感韵律外，评判者在所有任务上的意见都很一致。未来的研究将集中于完善评估，并开发与评估并行的治疗方案。
