Word-final (v) presents theweakest

Word-final (v) presents the
weakest point for students in this study with [v] typically being produced
less than 50% of the time and sometimes as low as 32.4% (See Table 9).
In pronunciation or conversation classes, much greater emphasis should
be placed on word-final (v). For (v) in initial position, emphasis should be
placed on conversational style, and to a much lesser extent on reading
passages.
