Jason Whitfield

Jason Whitfield's research examines speech motor control in healthy speakers and adults with neurological conditions, with a particular focus on people living with Parkinson disease (PD). He uses acoustic analysis, motion capture analysis, and other instrumentation to study speech and voice production across a variety of speaking conditions. Recent projects have examined the acoustic and kinematic consequences of clear and loud speaking styles, the effects of attentional demands and dual-task performance on articulatory and phonatory control, and the implications of these findings for behavioral treatment of individuals with PD.

Whitfield's teaching interests include speech and voice science, neuroanatomy and physiology, neurogenic communication disorders, and instrumentation for the analysis of speech. He is a coauthor of the textbook Speech and Voice Science, which is now in its fifth edition.

Whitfield is a member of the American Speech-Language-Hearing Association and the Acoustical Society of America. He has served on the editorial boards of the Journal of Speech, Language, and Hearing Research and Perspectives of the ASHA Special Interest Groups and currently serves as the editor of the Speech Science (Special Interest Group 19) section of Perspectives. Whitfield also regularly serves as a peer reviewer for academic journals in speech, language, and hearing science.
