Perceptual characterization of voice quality in nonadvanced stages of Parkinson's disease

from Journal of Voice

Perceptual characterization of voice quality in nonadvanced stages of Parkinson's disease Journal of Voice Parkinson's disease (PD) is a neurodegenerative disorder that impacts motor and nonmotor systems, and consequently influences voice. In later stages of the disease, people with PD develop salient hypokinetic dysarthria. However, it is unclear how extensive the voice impairment is in the nonadvanced stages of PD. Therefore, the aim of the current research was to investigate the auditory-perceptual characteristics of voice in people with Parkinson's disease (PWPD) in nonadvanced stages. READ MORE
