Abstract
The articulation of individuals with dysarthria has traditionally been described as consistent. However, conflicting findings have resulted from research examining intra-participant variation in the articulation of individuals with Parkinson's disease (PD) and hypokinetic dysarthria. The current study used electropalatography (EPG) to examine the degree of intra-participant variation in both tongue-palate contact patterns and duration of contact in a group of speakers with PD and hypokinetic dysarthria including consonant imprecision (n = 8). The study also aimed to determine if ageing contributed to any articulatory instability observed. Therefore, two control groups were employed consisting of aged adult (n = 7) and young adult (n = 8) speakers respectively. Participants were asked to read aloud the phrase “I saw a CVC today” were C = /t/, /s/, and /l/ and V = /a/. Intra-participant variation in tongue-palate contact was measured using the absolute and relative variability indexes. Coefficients of varia...
