• Resumen

  • Recent work suggests that Ukrainian represents a typologically rare bidirectional stress system with internal lapses, i.e. sequences of unstressed syllables in the vicinity of primary stress (Łukaszewicz and Mołczanow 2018a, b). The system is more intricate than the hitherto known bidirectional systems (e.g. Polish), and thus interesting from the theoretical perspective, as it involves interaction between free lexical stress and secondary stresses. Lexical and subsidiary prominence in Ukrainian have been shown to be expressed acoustically in terms of increased duration of the whole syllable. This leaves open the question of the role of classic vowel parameters in shaping prominence effects in this language. The present study fills this gap by investigating vowel duration, intensity, and F0 as potential acoustic correlates of primary and secondary stress in Ukrainian. It focuses on words with primary stress on the fifth syllable. Such words are predicted to have secondary stress on the first and third syllables. The results point to statistically significant lengthening of vowels carrying lexical stress as well as of those in the initial syllable, but not in the third syllable. A possible explanation is that other parameters, e.g. consonant duration, may be crucial in the case of word-internal subsidiary stress in Ukrainian.
