Voice Outcomes of Clear Speech Cueing in Individuals With Parkinson's Disease.

ABSTRACT:

Purpose

The purpose of this study was to investigate acoustic and auditory-perceptual voice outcomes of clear speech cueing in individuals with Parkinson's disease (PD).

Method

Speakers with PD completed speaking tasks (a spontaneous speech sample and a standard reading passage) in two speaking conditions: typical and clear speech. Acoustic measures of vocal intensity, fundamental frequency (f_o) variation, cepstral peak prominence (CPP), and low-to-high (L/H) ratio were calculated. Expert listeners completed auditory-perceptual ratings of the overall severity of dysphonia, breathiness, and strain of samples using visual-analog scales. Acoustic and auditory-perceptual measures were compared across speaking conditions and tasks.
