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.
