Locus equation for final stop voiceless consonants /p, t, k/ in Vietmese language

Many previous studies showed a remarkably linear relationship between onset frequencies of F2 transitions in relation to the F2 midvowel “target” frequencies for CVC tokens. Slope and y-intercept values of regression functions fit to these scatterplots (locus equations) were shown to serve as statistically powerful phonetic descriptors of place of articulation. Taking up again previous literature studies, the aim of the present work is to apply locus equation measurement to Vietnamese language, but for three final stop voiceless consonants /p, t, k/. Hence, this work presents a relationship between the F2v in relation to offset frequencies of F2 transition (F2off) for (C1)VC2 tokens. A Vietnamese corpus was built with nine vowels (six classical vowels and three specific vowels that present dynamic characteristics and shorter duration than classical ones). Comparisons with the locus equations of initial stop consonants /b, d, g/ that have the same places of articulation are given at the end of this study.
