“…Time series of the model parameters were estimated from a natural speech signal [iai] by means of an acoustic-to-geometric inversion (Schoentgen and Ciocea 1995a). Three types of stimuli were built from these time series: (i) isolated sustained vocods ([V] signals); (ii) the same sustained vocods presented between two sustained [i] ([i#V#i] signals, where # stands for a 20-ms silence); (iii) and vocods containing only [ia] and [ai] transition segments ([iVi] signals).…”

This paper presents a perceptual experiment on stimuli synthesized by means of a vocal tract area function model. The purpose was to compare the contribution of dynamic against static information to the identity of a coarticulated vowel. Three sources of information were perceptually analyzed: (i) the vowel nucleus; (ii) the acoustical contrast between the vowel nucleus and the "stationary" parts of its immediate context; (iii) and the transitions linking the stable parts of the speech signal. The results show that the vocods were better identified by dynamic information. This backs up the perceptual overshoot model proposed in Lindblom and Studdert-Kennedy (1967). However, this conclusion must be confirmed by further experiments.
