The C/D model and prosodic control of articulatory behavior.
The Converter and Distributor (C/D) model is a generative description of articulatory gesture organization for utterances. Its input comprises specifications for syllables by features, a paraphonologically augmented metrical structure, and system parameters for utterance conditions. A syllable-boundary pulse train is computed as a time function representing the skeletal rhythmic structure of the utterance. Control functions for articulators are computed by superimposing consonantal elemental gestures onto the base function, which includes voicing, vocalic, mandibular, and tonal functions associated with the pulse train. A preliminary analysis of microbeam data for experimental dialogues, using jaw opening as an approximate measure of the syllable magnitude, inferred syllable and boundary durations consistently with durational characteristics observed in the acoustic waveform.
