His broad research focus is to gain an improved understanding of the motor processes that underlie normal and disordered speech and voice production. Dr. Tasko is currently engaged in several lines of research. One line of work is aimed at evaluating the hypothesis that stuttering is a speech disorder that arises from faulty speech motor control. A second line of research focuses on understanding the various dimensions of normal speech motor control and learning. Dr. Tasko oversees a well-developed speech physiology laboratory that is equipped for recording speech acoustics, chest wall, vocal fold and oral articulatory motion, orofacial muscle activity and speech-related aerodynamic events. Therefore there are a variety of opportunities for those interested in exploring the acoustic and physiological bases of speech production.
