Specificity for coarticulatory vowel nasality in lexical representations.

Abstract

Surface-level phonetic details are used during word recognition. Yet, questions remain about how these details are encoded in lexical representations and the role of memory and attention during this process. The current study utilizes lexical repetition priming to examine the effect of a delay between hearing a word repeated with either the same or different coarticulatory patterns on lexical recognition. Listeners were faster to recognize repeated words with the same patterns of coarticulatory nasality, confirming that subphonemic information is encoded in the lexicon. Furthermore, when listeners had to adapt to more than one talker, greater coarticulatory specificity in delayed priming was observed suggesting that word-specific encoding of subphonemic details is an active cognitive process.
