Locus equation pour les consonnes /b/, /d/ et /x/ du vietnamien

Locus equation measurements are one approach used to characterise vocal tract resonances during stop consonant production, the place of articulation of the consonant and the nature of the vowel-consonant transition. Taking up again previous literature studies, the aim of the present work is to applying locus equation measurements to Vietnamese language, for two stop voiced consonants /b/ and /d/, and for the specific velar voiced fricative consonant //. Because Vietnamese is a tonal language, a specific corpus was built, in order to avoid as much as possible tonal co-articulation effects. We also take into account the two specific vowels that present dynamic characteristics. Comparisons with other languages are given at the end of this study.
