Perceptual Identification and Normalization of Synthesized French Vowels from Birth to Adulthood

摘要

This paper intended to determine invariant acoustic correlates of French vowels through synthetic vocal tract growth normalization. Perceptual analysis showed that the distance between F1 and F0 in Bark is a nearly invariant parameter of perceived vowel height. The front/back dimension is determined by F2-F1 or F3-F2, and rounding can be related to the effective second formant (F'2). These analysis are of great interest for the development of normalization procedures. Furthermore, results can shed light on the issue of perceptual invariance.
