Pascal van Lieshout, PhD
My research at the University of Toronto focuses on normal speech and speech disorders as related to neurogenic, structural or functional abnormalities. I use concepts and tools of dynamical systems theory (DST) to study oral coordination and oral motor learning. In particular, I like to explore the influence of different types of constraints on the dynamics of the oral motor system (e.g., the effect of syllable structure on speech movements and gestural coordination).

A sample of the current projcts I am involved in with students and collaborators includes the following:
  1. Amplitude and rate influences on coordination stability in normal speech 
  2. The influence of aging and disease on the relationship between acoustics and facial motion 
  3. The gestural origin of speech errors 
  4. Organ detection in infants 
  5. Multi-task constraints on oral motor control 
  6. The influence of aging on voice characteristics 
  7. Speech motor control in stuttering 
  8. Speaking style and articulation
