A speaker of Mexican Spanish read 405 declarative sentences containing nine distinct target syllables with an H* accent, under different prosodic conditions: end of intonational phrase, end of intermediate phrase, and phrase-medial (varying syllabic position in the word and distance to the next stressed syllable). A preliminary analysis shows that intrasyllabic segmental durations and prosodic factors such as adjacency to word, intonational, and intermediate boundaries, as well as stress clash, are key components in the prediction of peak location.
