摘要

Previous work on English disyllabic and trisyllabic words cannot distinguish two types of views on accentual lengthening: (1) phrasal accent affects a single, multisyllabic domain (the entire word), vs. (2) phrasal accent affects multiple, potentially separate, domains (e.g., the primary stressed syllable and the final syllable). In the present paper, we distinguish these views by examining the effect of phrasal accent on the durational patterns of English four-syllable words. We studied words of three types, with different positions of primary and secondary lexical stress: pattern 1000 (e.g. 藞presidency), pattern 2010 (e.g. 藢demo藞cratic), and pattern 1020 (e.g. 藞suffo藢 cating). Our results show that accent-related lengthening can affect multiple, potentially distinct, sites: the primary-stressed syllable, the secondary-stressed syllable rhyme (if the word has secondary stress), the onset of the word-initial syllable, and the final syllable. In addition, lengthening can 鈥渟pill over鈥?from a primary-stressed syllable onto a following unstressed syllable. Patterns of accent-related lengthening on onsets vs. rhymes are qualitatively different for stressed vs. word-edge sites, suggesting separate lengthening mechanisms.
