Vietnamese Subtitle Generator

Vietnamese subtitle generation handles all six tones (ngang, huyền, sắc, hỏi, ngã, nặng) with high accuracy. The system recognizes Vietnamese phonetics and correctly applies tone marks (à, á, ả, ã, ạ) based on word meaning and context. Works with all major Vietnamese dialects including Northern (Hanoi), Central (Huế), and Southern (Saigon) variations. Audio clarity and speaker dialect affect results, so clear recordings produce the best subtitles.

The subtitle generator recognizes all three major Vietnamese dialect groups. Northern Vietnamese (Hanoi standard) with clear consonant pronunciation, Central Vietnamese (Huế dialect) with unique phonetic features and preserved distinctions, and Southern Vietnamese (Saigon dialect) with merged tones and softer pronunciation. The system adapts to regional vocabulary differences, local expressions, and colloquial speech specific to each region.

All 12 Vietnamese vowel variants are supported: a, ă, â, e, ê, i, o, ô, ơ, u, ư, y, plus the đ consonant. These combine with all six tone marks to create complex characters like ằ, ắ, ẳ, ẵ, ặ and hundreds of other combinations. Vietnamese orthography rules are followed automatically, with correct diacritics applied based on spelling conventions and word context.

Yes, built-in translation converts Vietnamese subtitles to English or any of 120+ other languages with one click.
