Title: Vowel-vowel transitions, analysis, and modeling
Abstract:Male and female vowel-vowel formant transitions are analyzed using cepstral techniques. The first three formants are detected and represented as trajectories in the F1−F2, F1−F3, and F2−F3 planes.

The first three formants are detected and represented as trajectories in the F1−F2, F1−F3, and F2−F3 planes. Distinctive formant trajectories are clearly revealed, exhibiting specific trajectory angles at the onset during the initial vowel and at the offset during the target vowel. Formant stabilities are also studied. Generally, depending on the vowel identity and the vowel context, either F1 or F2 is kept almost stable. These trajectories are interpreted using a region concept [Mrayati et al., Speech Commun. 7, 257–286 (1988)]. Trajectories predicted by the region model combined with an extremely simple dynamic strategy correspond well with those observed on natural speech. Explanations on the articulatory timing control can be deduced and compared with published cineradiographic and labiofilm data.Read More
