Prosem Lecture: What Altered Auditory Feedback Can Tell Us About Speech Motor Control, Planning, and Disorders
October 4, 2021 @ 12:00 pm - 1:00 pm
Presenter: Ben Parrell, PhD, Assistant Professor, Communication Sciences and Disorders, Faculty Trainer, Neuroscience Training Program, University of Wisconsin–Madison
Topic: What Altered Auditory Feedback Can Tell Us About Speech Motor Control, Planning, and Disorders
In this talk, I will present an overview of recent work from my lab using real-time perturbations to the auditory feedback speakers hear about their own speech to assess the speech motor control system. I will show how these auditory perturbations can be harnessed to 1) examine sensorimotor control of both spatial and temporal aspects of speech articulation, 2) probe the details of speech motor planning and its interaction with the linguistic system, and 3) assess and (potentially) treat control deficits in speech motor disorders. Lastly, I will examine some limitations and misconceptions of what we can learn from auditory perturbation paradigm and suggest one way to work with these limitations when studying motor speech disorders.
