Phonetics of European Portuguese stress: A nonce word experiment

Abstract

This paper investigates the acoustic correlates of stress in European Portuguese. Using a nonce word experiment, this study controls the phonological environment of the stimuli so stressed and unstressed vowels with the same quality can be directly compared. Of the five acoustic measures examined, duration is the most robust correlate of stress, but the effect is limited to certain vowels and speakers. Care is taken to separate the effects of independent phonological processes on acoustic properties that are also influenced by stress.
