Individual Differences in the Formant Dynamics of Vowels at Different Levels of Stress

University of Cambridge, UK

This paper examines individual differences in aspects of the formant dynamics of vowels at three levels of prosodic stress. Experiment 1 compares formant contours of /aɪ/ under nuclear and non-nuclear stress produced by five subjects. Experiment 2 examines vowel-to-vowel coarticulation differences in the formant frequencies of /ə/ produced by five subjects. The trajectory of F1, F2 and F3 of /aɪ/ yields distinguishing features for each of the speakers, with differences particularly marked at the non-nuclear stress level. Individual speakers coarticulate full vowels with /ə/ to varying extents in F1 and F3, and to a greater but more uniform extent in F2, however these differences are not as clearly speaker-specific as those identified in the formant dynamics of the stressed vowels in Experiment 1.
