The Converter/Distributor (C/D) model, as proposed by Fujimura is theoretically grounded on articulatory observations of X-ray microbeam (XRMB) data that show that utterance syllable prominence patterns “dictate” the size, timing and phrasing of articulatory movements. This paper briefly addresses some key differences between the C/D model and Articulatory Prosody (AP) before moving on to describe some of the basic components of the C/D model, e.g., the phonological prosodic input to the model, the Converter, which outputs, among other things, descriptions of syllable prominence patterns, prosodic boundaries, and syllable edge features, and the Distributor which enlists “elemental gestures” to articulatorily implement feature sets. Examples from previous research inspired by the C/D model illustrate how articulatory events, i.e., patterns of jaw lowering, account for the temporal organization of spoken language; also, how second language speakers tend to carry over their first language patterns of jaw lowering. Some applications of the C/D model are discussed, including first and second language acquisition, clinical applications, and new insights into prosodic phonology. The final section summarizes some of the strengths of the C/D model as well as the yet-to-be investigated aspects of the model
