Although the salient characteristics associated with Parkinson’s disease (PD) are most commonly linked to motor deficits, including tremor and rigidity, a majority of individuals with PD also experience a variety of sensorimotor speech deficits. While listeners often describe the speech of individuals with PD as unnatural or unintelligible, reflecting many of the phonatory, articulatory, and prosodic deficits linked to the disorder, individuals with PD tend to minimize or even deny their speech differences. Because of this discrepancy between listeners’ perceptions of the speech of individuals with PD and the PD patients’ perceptions of their own speech, researchers have recently begun to shift their focus from the speech production deficits associated with PD to a potential speech perception deficit within this population. This paper seeks to explore some of the current research and perspectives surrounding the possible speech perception deficits associated with PD, as well as further examine and compare the effects of listener perception and self-perception on the overall speech naturalness and intelligibility of individuals with PD. A Comparison of the Effects of Self-Perception and Listener Perception on the Speech Naturalness and Intelligibility of Individuals with Parkinson’s Disease According to Fahn (2003), Parkinson’s disease (PD) is a progressive neurodegenerative disease of unknown etiology that can occur at any age, though most commonly develops in
