The paper analyses Vietnamese vowel-semivowel productions, including classical and shorter vowels in terms of the vowel duration in relation with the final semivowel duration, the formant transition duration, and the formant transition slopes. The results show that in the vowel-semivowel context, there is a relationship between the vowel duration and the final semivowel duration. Moreover, in the same context of a final semivowel, classical and shorter vowels can be differentiated by at least one of the formant transition slopes. This allows estimating the role of the final part in its articulation with shorter vowels in Vietnamese.
