Stuttering, Speech Perception

Research Interests

My main area of interest lies in the field of stuttering, especially in relation to what it can tell us about the processes of speech perception / production. Specifically, I have been interested in exploring the neural mechanisms that may be involved in eliciting stuttering those that ‘inhibit’ its occurrences. As stuttering is such a dynamic pathology that can be turned ‘on’ and ‘off’ under certain speaking conditions, it provides an excellent means of comparing normal and pathological speech systems with the hope of shedding light on the intricate neural mechanisms surrounding normal speech and language processes. My collaborative research also investigated physiological mechanisms associated with stuttering (i.e., how listeners react physiologically and anticipatory arousal prior to speaking in people who stutter). In addition, I have investigated how stuttering can disrupt manual functioning simultaneously with speech.

My clinical research involves investigations into the most efficient and effective means of managing stuttering and tailoring therapy to meet individual needs. I encourage educating others about the ‘involuntary’ nature of stuttering so as to reduce feelings of guilt and shame about stuttering and any relapse from therapy. I also promote attaining acceptable levels of fluency that are possible with the least compromise to speech naturalness, the least amount of added effort in speech production.

Recently, I have also been collaborating in electrophysiological research aimed at measuring cortical motor activity during speech processes of speech perception. Specifically, we have been investigating mu wave suppression and attempting to localize sources of suppression using sLORETA imaging solutions.
