Temporal aspects of articulatory control

This contribution is focused on temporal aspects of articulatory control during the production of speech. We review a set of computational and experimental results whose focus is on intragestural, transgestural, and intergestural timing properties. The computational results are based on recent developments of the task-dynamic model of gestural patterning. These developments are focused on the shaping and relative timing of gestural activations, and on the manner in which relative timing among gestures can be interpreted and modeled in the context of systems of coupled nonlinear oscillators. Emphasis is placed on dynamical accounts of prosodic boundary influences on gestural activation patterns, and the manner in which intergestural coupling structures shape the timing patterns and stability properties of onset and coda clusters.
