Contrastive Analysis in Phonetic Characteristics of Thai and Vietnamese Tones

Patthida Bunchavalita


This paper is a contrastive analysis of phonetic characteristics of Thai and Vietnamese tones using the phonetic characteristics based on the methodologies from the analyses of Arthur S. (1962), Hoàng ThịChâu (2009), Đoàn Thiện Thuật (2016) and Nguyễn ThịHai, (2017). This analysis finds that, aside from the difference of quantity of toneme, there are additional differences including fundamental frequency, length, tone shape, pitch, and voice quality. Tho in the Thai tonal system does not occur in the Vietnamese tonal system. Conversely, hỏi, ngã and nặng in the Vietnamese tonal system do not occur in the Thai tonal system.
