Abstract

![CDATA[The present study investigated the extent to which variation along formant trajectory dimensions – considered both separately and simultaneously – manifests in the English diphthongs CHOICE, FACE, MOUTH, GOAT and PRICE. The sources of variation were phonemic category, flanking consonants, speaker’s gender and speaker’s regional background. Formant trajectory dimensions were overall and timevarying first (F1) and second (F2) formant trajectories as parameterised by their means and time-varying slopes and curvature using the discrete cosine transform. Phonemic category was robustly predicted by variation in the combination of F1 and F2 means and slopes, whereas flanking consonants were not. Gender was strongly predicted by variation in F1 and F2 means, but not in F1 and F2 time-varying aspects. Regional background emerged in the variation of both F1 and F2 means, slopes and curvature to roughly similar extents. Given the acoustic multidimensionality of vowels, variation is most appropriately viewed with a multivariate approach.]]
