Pretonic Lengthening as the Lexical Stress Domain Extension

Beata Łukaszewicz, Janina Mołczanow, Anna Łukaszewicz

This paper reports on an acoustic study of pretonic lengthening in Ukrainian, a language with a hybrid metrical system comprising lexical stress and grammatical secondary (rhythmic) stress, both cued by vowel duration ([1], [2]). The existence of pretonic lengthening has gone unnoticed in the traditional descriptions, and although recent acoustic research ([1], [3], 4]) has pointed to its presence in Ukrainian, this phenomenon has not been systematically investigated. The phenomenon is interesting because by reducing the temporal difference between the pretonic and the tonic syllable, pretonic lengthening weakens the durational cue to lexical stress. It also distorts the otherwise regular iteration of secondary stresses. In this paper, we report on the measurements of the duration and formant (F1/F2) structure of the vowel /a/ in different prosodic positions (lexical stress and three preceding syllables). The analysis of the data collected from 11 native speakers of Ukrainian points to a gradual effect of lengthening and the presence of vowel undershoot across syllables preceding lexical stress. We argue that the existence of pretonic lengthening in Ukrainian is closely related to the domain of lexical stress, and may reflect a more universal anticipatory effect induced by lexical stress.
