The main purpose of this research is to investigate stylistic variation of (v) in
the English of Thai speakers. Three styles are chosen in this study: conversation (informal),
reading text (formal), and minimal pairs (very formal). The data analysis shows that there is
a significant difference between the use of syllable-initial and word-final (v). Most of
syllable-initial (v) occurs as [vI in each style while the word-final (v) occurs most frequently
as [t], followed by [v].
