Vietnamese interview text depends on tone and vowel marks that can change the meaning of a short syllable, not merely its appearance. Route predominantly Vietnamese speech with vi, then give names, regional wording, number expressions, and borrowed English terms a source-linked diacritic review.

What to expect from Vietnamese audio
Vietnamese orthography marks tone and vowel distinctions that may be carried by very short syllables, so missing diacritics can change meaning rather than merely style. The practical review targets are tone marks, vowel diacritics, regional wording, names, numbers, and borrowed terms. Tone marks are part of standard Vietnamese orthography and should be reviewed carefully in names and short words.
Review the details that carry meaning
Regional pronunciation, compounds, numbers, and English technical terms need source-linked correction. Use word-level playback for tone marks, vowel diacritics, regional wording, names, numbers, and borrowed terms; a correction is accepted only when the surrounding clause and project convention support it.
