Abstract
Purpose: This study investigated the possible relationship between hypokinetic speech production and speech intensity perception in patients with Parkinson’s disease (PD). Method: Participants included 14 patients with idiopathic PD and 14 matched healthy controls (HCs) with normal hearing and cognition. First, speech production was objectified through a standardized speech intelligibility assessment, acoustic analysis, and speech intensity measurements. Second, an overall estimation task and an intensity estimation task were addressed to evaluate overall speech perception and speech intensity perception, respectively. Finally, correlation analysis was performed between the speech characteristics of the overall estimation task and the corresponding acoustic analysis. The interaction between speech production and speech intensity perception was investigated by an intensity imitation task. Results: Acoustic analysis and speech intensity measurements demonstrated significant differences in speech production between patients with PD and HCs. A different pattern in the auditory perception of speech and speech intensity was found in the PD group. Conclusions: Auditory perceptual deficits may influence speech production in patients with PD. The present results suggest a disturbed auditory perception related to an automatic monitoring deficit in PD.
