Research My research
investigates the dance of the tongue, lips, and jaw--the motions of
the speech articulators. Speech movements are quick, fluid, overlapping, and
coordinated. They interact with the transient rhythms of speech and provide a basis for the
emergence of linguistic systems. By observing the spatial and temporal effects
of perturbations of speech motor planning, we can gain insight into how
linguistic systems are represented cognitively. One of my main interests is in
how articulatory, rhythmic, and prosodic systems interact--these interactions
constrain and inform our theories of the prosodic hierarchy. I am also
interested in the interplay between motor and sensory representations in
working and long-term memory, as well as their respective contributions to
sound change. My theoretical approach is based upon dynamical modeling of
interactions between articulatory and prosodic systems during the planning and
production of speech. |
