Rhythmic stress or word-boundary effects? Comparison of primary and secondary stress correlates in segmentally identical word pairs

Most available studies of prominence have been based on experimental designs in which potential correlates of stress are simultaneously involved in marking other aspects of linguistic structure. However, the confounding impact of factors such as segmental structure or boundary effects has been widely acknowledged in the phonetic literature but rarely submitted to rigorous scrutiny (e.g. [1], [2], [3]). The present study investigates acoustic correlates of lexical and rhythmic stress in Ukrainian in an experiment designed to control for the potential segmental and boundary confounds. Ukrainian has been reported to have both word-initial and word-final secondary stress ([4], [5], [6]); therefore, metrical prominence effects in word-initial and word-final positions coincide with potential boundary effects. In the present pilot study, based on four-syllable words collected from four Ukrainian speakers, we compare pairs of words having the same number of syllables and the same segmental structure but differing in terms of the position of lexical stress and rhythmic structure. The results point to statistically significant differences in vocalic (and to some extent also consonantal) duration which depends on the presence versus absence of stress.
