The role of prosody in the mental lexicon.

Current models of spoken word recognition take into account factors such as word frequency, word onset cohort size, and phonological neighborhood density. Using the word onset gating technique we tested word recognition when bandpass filtering was used to allow subjects to hear the full prosodic pattern of a word (number of syllables and syllabic stress), deprived of segmental information beyond that contained in the onset gate. Subjects also heard either word onsets plus duration information or only word onsets. Results suggest that word prosody is represented in the mental lexicon and is effectively used by listeners in spoken word recognition. Copyright 1999 Academic Press.
