Oral Dynamics Laboratory


The Oral Dynamics Lab (ODL) is a research laboratory in the Department of Speech-Language Pathology at the University of Toronto. Founded by Pascal van Lieshout, the ODL conducts groundbreaking research in speech science and oral motor control.


Research in the ODL aims at studying, describing and explaining the mechanisms involved in the control of oral motor function as related to normal and disordered speech and swallowing in human subjects across the lifespan.

Research areas (keywords)

Oral motor control; speech production; dynamical systems theory; speech errors; sensory motor interaction; Gestural Phonology; speech disorders; swallowing; speech science
