Prosody exists in phonological form and in its phonetic expression in speech production and perception. Phonological models of prosody characterize prosody in terms of discrete, n-ary features that are hierarchically organized. On the other hand, phonetic evidence of prosody is found in complex patterns of variation in pitch, intensity and duration, which suggests that prosody features are essentially gradient and continuous-valued. This course examines the evidence for gradient and discrete prosodic features in the variability of acoustic prosodic measures across utterances, speakers and speech styles, and reviews the arguments for discrete prosodic structures and features in phonological accounts. We will discuss cognitive models of prosody that account for the mapping between abstract phonological representations based in discrete features, and detailed phonetic representations over gradient features, drawing on recent proposals for hybrid abstract-exemplar models of speech encoding. Other topics include how discreteness is represented in models of prosody production based on the coupled-oscillator architecture of Articulatory Phonology, and the need for relational models of prosody to capture notions of relative strength in the syntactic, semantic and pragmatic features that are encoded in prosodic form.

- Phonetic correlates of prosody: statistical models of discrete vs. gradient features
- Cognitive representations of prosody: abstract, exemplar, and hybrid models
- Discreteness in prosody production
- Relational models of prosody at the interface with structure and meaning
