A Perceptually-Driven Account of Onset-Sensitive Stress

Abstract

This paper explores onset-sensitive stress from a typological, phonetic and phonological perspective. A phonetic study of three onset-sensitive stress systems suggests a close match between onset weight distinctions and a phonetic measure of perceptual energy, such that phonological weight criteria are the phonetically most effective ones. Perceptual considerations also offer an explanation for other typological observations, including the relative rarity of onset-sensitive stress, the greater weight of low sonority onsets, and the subordination of onset-sensitive weight distinctions to rime-based ones in languages with both types of weight distinctions. Onset-based weight criteria are effectively modelled using a skeletal slot model of the syllable referenced by a family of prominence constraints requiring that heavy syllables be stressed and that light syllables be unstressed.
