The Converter/Distributor (C/D) Model of phonetic implementation represents the temporal organization of speech signals, syllables being the minimal phonological units for concatenation, as articulatory and phonatory actions, depicted as complex, multi-dimensional, semi-quantitative patterns. Beyond F0 and intensity for prosodic description, the C/D model describes voice quality control by relating the temporal characteristics of glottal changes, linked with respiratory control, to articulatory movements of tongue, lips, velum, and mandible. Stress is represented as syllable pulse height, i.e., syllable magnitude, while the rhythm of an utterance is the organizational pattern of syllable magnitude distribution within the time domain of phrasal speech production.
