Dr. Matthew Goldrick
Abstract Recent work in speech production has suggested the presence of lexically conditioned phonetic variation – the effect of whole-word properties (e.g., lexical frequency, neighbourhood density) on the fine-grained phonetic realization of that word (e.g., word duration, precise voice onset time of initial stops). A number of cognitive mechanisms have been proposed to account for such effects, including cascading activation in speech production, listener modelling, and exemplar-based memory systems. I’ll discuss recent experimental work favoring a production-internal interaction account. I’ll then sketch how this account can be formalized within a Harmonic Grammar framework by incorporating gradient phonological representations.
