Exploring The Temporal Variability Of Speech Intensity, Speech Intelligibility, And Communicative Participation In Individuals With Hypophonia And Parkinson’S Disease, Cynthia Mancinelli Nov 2019

Exploring The Temporal Variability Of Speech Intensity, Speech Intelligibility, And Communicative Participation In Individuals With Hypophonia And Parkinson’S Disease, Cynthia Mancinelli

Hypophonia, or reduced speech intensity, is frequently observed in individuals with Parkinson’s disease (PD). This speech deficit can impact speech intelligibility and communicative participation. However, there is little empirical evidence exploring the day-to-day variability of speech and communicative participation in individuals with PD. The purpose of this study is to investigate the temporal variability of acoustic and perceptual speech measures and psychosocial measures in individuals with hypophonia and PD. Additionally, this study seeks to examine the relationships among measures of speech intensity, speech intelligibility, self- and proxy-rated communicative participation, demographic factors, and non-speech factors. Twenty-three participants with PD, 23 primary …


Changes In Speech Intelligibility And Acoustic Distinctiveness Along A Speech Rate Continuum In Parkinson’S Disease, Thea Knowles Jul 2019

Changes In Speech Intelligibility And Acoustic Distinctiveness Along A Speech Rate Continuum In Parkinson’S Disease, Thea Knowles

Asking a person to speak slowly is a common technique in speech therapy for people with Parkinson’s disease (PD). Slowed speaking rates are thought to bring about changes in speech production that make it easier for people with speech impairments associated with PD to be understood, but this is not always the case. Furthermore, research suggests that using faster speech does not necessarily lead to decreases in speech intelligibility for some people with PD. Most studies of rate modification in PD have only included one or two rate adjustments to investigate the relationship between speech rate, intelligibility, and acoustic aspects …
