Original Abstract

Parkinson's disease (PD) is the second most frequent neurodegenerative disorder. Up to 90 % of PD patients suffer from speech disorder called hypokinetic dysarthria (HD). The goal of this work was to perform quantitative acoustic analysis of poem recitation in order to identify presence of HD. We employed conventional acoustic features to quantify specific HD disorders such as articulation, prosody, speech fluency and quality. It was observed that there is only mildly strong correlation between these speech features and diagnosis of the speakers. Next, we performed an univariate classification with these results of sensitivity in specific HD domains: imprecise articulation (62.63 %), dysprosody (61.62 %), speech dysfluency (71.72 %), and speech quality deterioration (59.60 %). The classification performance was improved by a multivariate classification, where we achieved sensitivity of 83.42 % using only two features describing imprecise articulation and speech quality deterioration in HD. Promising potential of the selected speech features and especially the use of poem recitation task to quantify and identify HD in PD was demonstrated.
