Abstract

Speech produced by two speakers was manually segmented, generating two databases with 18,000 and 6,000 vowel segments. The effects on vowel duration of several contextual factors were measured, including those of syllabic stress, pitch accent, the identities of adjacent segments, the syllabic structure of a word and proximity to a syntactic boundary. With statistical techniques for de-confounding factors, detailed characterizations of the effects of the factors and their interactions could be given, which were then summarized in the form of a simple equation for predicting vowel duration from context.
