Abstract
Changes in speech rate have long been identified as a prominent sign of dysarthria. At the same time, such changes have been reported in the literature on normal ageing. This study aimed to provide information on the speech rate behaviour in the three participant groups, comprising speakers with Parkinson's Disease (PD), healthy age matched control speakers (CON), and an older non-dysarthric group with mild cognitive decline (DEM).The analysis revealed that the CON and PD group performed similarly for articulation rate whereas the DEM speakers spoke significantly more slowly. This relationship was reversed for pausing behaviour, where the DEM and CON groups performed similarly whilst the PD speakers produced a higher degree of pause time. All groups could change their articulation rate significantly from habitual to slow and fast conditions. However, the groups differed in the amount of change, with CON speakers showing the greatest and DEM the smallest amount of differences in articulation rate. The data did not identify clear performance predictors. However, there was a suggestion that the speakers' cognitive skills had an impact on their speech performance.
长期以来,语速变化一直被认为是构音障碍的一个显著标志。与此同时,关于正常老龄化的文献中也有此类变化的报道。本研究旨在提供三个参与者群体的语速行为信息,其中包括帕金森病患者(PD)、与年龄匹配的健康对照组(CON)和患有轻度认知功能衰退的非构音障碍老年组(DEM)。在停顿行为方面,这种关系正好相反,DEM 组和 CON 组的表现相似,而 PD 组说话者的停顿时间更长。从习惯到慢速和快速,所有组别都能显著改变发音速度。但是,各组的变化幅度不同,CON 组的发音速度差异最大,而 DEM 组的发音速度差异最小。这些数据没有发现明确的成绩预测因素。不过,有迹象表明,说话者的认知能力对他们的语音表现有影响。
