Parkinson Disease (PD) has been found to have significant effects on speech production, including deficits in phonation and prosody. Studies of self-perception of speech and voice by individuals with PD suggested that individuals with PD may be unaware of their own speech deficits. It was also hypothesized previously that caregivers (or other non-neurologically impaired listeners) would show awareness of the speech deficits associated with PD. However, neither the claim that individuals with PD are unaware of their deficits, nor the claim that caregivers are aware of deficits have been comprehensively examined. The current study examined ten individuals with PD (speakers) their primary caregivers. Individuals with PD completed a paragraph reading and both those individuals and their caregivers were asked to rate the speech across six perceptual measures. Trained listeners also rated the paragraph reading across the same six perceptual measures. Perceptual measures were correlated with acoustic measures, and perceptual measures were studied for significant differences across listener types. Results showed five correlations between trained perceptions and acoustics, three (one meaningful) correlations between self-perceptions and acoustics, and no correlations between caregiver perceptions and acoustics. Across listener type, trained listener perceptions were found to be significantly higher when compared to self-perceptions on three speech characteristics, and were significantly higher than caregiver perception on one speech characteristic. Although no significant differences were found between self-ratings and caregiver ratings, descriptive analysis of the correlation results may indicate caregivers underestimate the effects of PD on speech and voice. Clinical implications are discussed, including the impact this finding may have on PD patients and caregivers regarding their abilities to seek and attend treatment for speech and voice.
