Vowel duration in stressed and unstressed syllables in spontaneous English
Original language description
Many phonetic “truths” are based on descriptions of controlled speech material, and verifying their validity in spontaneous productions is essential. The study investigates vowel duration as an acoustic correlate of stress in spontaneous English, in communicatively motivated contexts, specifically in British and American political debates. The analysis confirms the significant effect of stress on vowel duration and also considers additional factors influencing segmental duration like vowel length, phrase-final position, vowel height, or the nature of the following segment. In addition to stress, multiple regression analysis identifies vowel length, phrase-final position and vowel height as the most influential vowel duration predictors. Despite the variability of spontaneous speech, vowel duration proves to be a reliable correlate of stress, supporting the findings from controlled-speech research.
