Studies in the Phonology of Asian Languages X: Intertonal Influences in Two-Syllable Utterances of Vietnamese. Final Technical Report, March 1970 - June 1972.

This study, tenth in a series of publications entitled "Studies in the Phonology of Asian Language," describes the phonetic variation of the six tones in two-syllable utterances of Vietnamese. The study is based on acoustic measurements of actual words and phrases. Findings of the study concern: (1) overall pitch height of a tone, (2) tone variants and crossing in given syllable positions, (3) range of variation of tones, (4) differentiation of level tone from the falling tone, and (5) environmental influence on the six-tone contrast.
