On the acoustic and perceptual characterization of reference vowels

Résumé

The correlation between front/back tongue position and second formant (F2), and high/low tongue position and first formant (F1), are often overestimated in the literature, whereas F3 and F4, and the relative amplitude of the formants are often neglected. Due to the lack of a clear acoustic definition of phonetic symbols (especially cardinal vowels), the same phonetic symbol is often used to transcribe very different phonetic realities. On the basis of the acoustic theory of speech production (Fant) and of an articulatory model (Maeda), this presentation brings out well-defined acoustic-perceptual characteristics for a number of vowels to be used as references. These vowels are characterized articulatorily by the position of one or more clear constrictions along the vocal tract, and acoustically by an almost complete merging of two adjacent formants. Specifically, we discuss the transcription of subtle but audible details in the realisations of the "same" vowels in six languages, and the common attributes shared by vowels and their surrounding phonemes, involving a tendency to share tongue and lip configurations. Some proposals are made for extending this model to consonants.
