Abstract

A study that was conducted to examine the vowel productions in a corpus of spontaneous speech is presented. Several alternate accounts of the nature of VISC in speech production are also briefly discussed. Research on vowel identification has suggested that the onset+offset hypothesis best captures the perceptual cues listeners use. Studies on the production of vowels in careful citation speech have added to this theory with models that include vowel duration and pitch. On the plots, the arrow indicates the average vowel offset and the labeled end represents the average vowel onset. The linear VISC movement shown is gathered from the onset+offset model. It is notable that even though the vowel spaces differ between males and females, the trends in VISC movement remain the same. Most studies on vowel identification make use of a onset+offset theoiy of VISC, with the data here point to the discriminative importance of this hypothesis in spontaneous speech productions.
