Abstract

We examined the acoustic correlates of lexical stress in the non-Pama-Nyungan language Wubuy (Northern Territory, Australia). We tested two hypotheses about stress: that stress is determined by (1) a combination of syllable position in prosodic word and quantity sensitivity, or (2) by position alone. To test these hypotheses, we elicited trisyllabic noun roots differing in position of heavy syllables in frame-final environments from 3 speakers. We found that both position and predicted stress based on prior phonological descriptions could account for many correlates (segment and syllable duration, f0, intensity, vowel formants) although overall syllable position appeared to account for more ..
