My general research
interest is the understanding of the processes
of speech production and speech perception.
My speech production research focuses on
the control of vocal tract and facial motion:
what are the units of coordination; how
are sequences of actions implemented; what
form do the central commands take in fluent
speech. I use a number of techniques to
gather physiological data, including electromyography,
kinematic analysis of OPTOTRAK data, and
image processing of X-ray images from the
X-ray Film Database.
My speech perception research focuses
on audiovisual integration during face-to-face
communication: what are the visual cues
for individual speech sounds; what are
the necessary and sufficient conditions
for audiovisual fusion; what patterns of
eye movements are observed during face-to-face
communication. In this area, much of our
work has focused on the McGurk effect.
Selectly, I have begun a project on facial
and vocal tract modeling. The purpose of
the work is to produce realistic facial
animations that can be used in controlled
audiovisual experiments and to generate
models which summarize our knowledge of
the speech production process. |
