In this contribution the use of web resources for the longitudinal study of speech rhythm of a 'well-known' person diagnosed with Parkinson's disease, the American actor Alan Alda, is proposed. A corpus of 20 speech samples produced in the period between 1979 and 2021 was collected from the web. A rhythmical analysis was conducted, based on two parameters: the percentage of vocalic portion on the total duration of the utterance (%V) and the VtoV, the mean duration of the interval between two consecutive vowel onset points. The results of this study confirm an early alteration of rhythm in parkinsonian speech, with an abnormal increase of %V, already occurring some years before the clinical diagnosis. The observation of speech rhythm variation can therefore be considered as the basis for the realization of a sustainable and non-invasive procedure in support to early diagnosis of Parkinson's disease.
本文提出利用网络资源对被诊断患有帕金森病的“知名”人士——美国演员艾伦·阿尔达的言语节奏进行纵向研究。从网络上收集了1979年至2021年期间他所发表的20个语音样本组成的语料库。基于两个参数进行了节奏分析：元音部分在话语总时长中的占比（%V）以及VtoV，即两个连续元音起始点之间间隔的平均时长。本研究结果证实帕金森病患者言语节奏的早期改变，即%V异常增加，这在临床诊断前几年就已出现。因此，言语节奏变化的观察可被视为实现一种可持续且非侵入性程序以辅助帕金森病早期诊断的基础。
