Modeling the durational difference of stressed vs . unstressed syllables

Speech production exhibits temporal coherence among speech gestures, and also systematic modulation of durational patterns as a function of the hierarchical level of prosodic structure, e.g., the foot. Intergestural coherence has been understood with reference to dynamic coupling within an ensemble of planning oscillators, and a coupled oscillator model of intergestural timing has been employed to simulate relative timing patterns observed inter-gesturally within and between syllables. In this paper, we integrate temporal modulation gestures into the oscillator model and modulate coupling parameters to simulate the durational asymmetry between stressed and unstressed syllables.
