My primary area of research interest is speech motor control in adult neurogenic populations, specifically Parkinson’s disease. My research has included study of interarticulator timing (phonatory-articulatory) adjustments in response to a new behavioral voice treatment for individuals with Parkinson’s disease. Previous areas of research have also included developmental speech perception for an alveolar to velar place contrast, and changes in auditory-perception associated with Parkinson’s disease. It is clear from anecdotal reports and previous psychoacoustic studies of intensity perception, that some individuals with Parkinson’s disease exhibit changes in auditory perception. Such changes in auditory perception may limit an individual’s ability to monitor their vocal intensity levels. While auditory perceptual training for select acoustic features (e.g. intensity) has shown promising results in healthy aging adults, it is unclear whether its clinical utility extends to adult neurogenic populations. Future research will include auditory perceptual training for intensity targets in persons with Parkinson's disease.
