Prosem Lecture: Leveraging an Adaptable Speech Perception System for Dysarthria Remediation
November 29 @ 12:00 pm - 1:00 pm
Presenter: Stephanie Borrie, Ph.D., Associate Professor, Communicative Disorders & Deaf Education, Utah State University
Topic: Leveraging an Adaptable Speech Perception System for Dysarthria Remediation
Listeners rapidly adapt to unfamiliar talkers, mapping acoustic cues to linguistic categories. This perceptual adaptation informs subsequent (and improved) processing of the speech signal. With a focus on the neurologically degraded signal of dysarthria, this talk presents a series of behavioral studies that test theoretical postulations about how and when listeners adapt to disordered speech. Data that points to the source of learning and the listener, talker, and task parameters that mediate adaptation will be discussed. Collectively, the results support a novel approach for speech remediation: perceptual training to improve intelligibility of talkers with dysarthria. The talk concludes with direction for translational studies to move this work from bench to bedside.
