Yami (Austronesian; Taiwan) has been impressionistically reported to exhibit default final-syllable stress for most content words, aside from the class of stative verbs which show penultimate stress. To empirically verify these claims, an experiment was conducted with 5 speakers contrasting the production of trisyllabic nouns (final stress) with stative verbs (penultimate stress). Duration, maximum and mean intensity, and maximum and mean F0 were measured for vowels in penultimate and final syllables (n=430). Linear mixed-effects models reveal that: for each word class, stative verbs showed significantly greater values in penultimate than final syllables for all variables, while final syllables of nouns were distinguished from penultimate syllables almost exclusively by higher maximum F0. When comparing syllables across word classes, penultimate syllables of stative verbs were greater in duration and F0 than nouns, but minimal difference was found between final syllables of stative verbs and nouns. Therefore, penultimate stress is robustly cued by duration, intensity, and F0, but stable correlates were not found for final stress, thereby challenging its validity. The higher maximum F0 of final (over penultimate) syllables in nouns could insinuate the presence of an accent, whose divergent behavior suggests that it may not be lexical, but rather phrasal, in nature.
