Voice translator, dubbing or recording translator?
Most people searching for a English to Vietnamese voice translator want one of four things. This page does two of them.
To translate your own voice, record it with the Online Voice Recorder (WAV or WebM download), or use your phone's voice memo app, then upload the file here.
| You want to | What does it | This page |
|---|---|---|
| Talk with someone live, English to Vietnamese | A phone translator app in conversation mode | No: it does not translate while you speak |
| Hear the recording spoken in Vietnamese | A dubbing tool | No: you get Vietnamese text and subtitles, not a voice-over |
| Read or quote a English recording in Vietnamese | A recording translator | Yes: English transcript and Vietnamese translation, line by line |
| Put Vietnamese subtitles on a English video | A recording translator with SRT or VTT | Yes: download SRT or VTT |
How accurate it is, and how fast
We measure the first step, the English transcript, on 80 clips from the public FLEURS test set: 4.8 words in 100 come out wrong on our premium engine and 6.6 in 100 on the standard engine (word error rate, test run October 20, 2026). We have not run a test set on the translation step itself, so read the result as a strong first draft.
The transcript is the slow part. Over the last 14 days, half of the hour-long files on the site were transcribed in under 2 minutes and 9 in 10 within about 6 minutes (587 files, measured November 14, 2026). Then the transcript is translated.
Machine translation is good for understanding a recording and for a first draft. For anything legal, medical or official, have a fluent speaker check it before you rely on it.
English to Vietnamese: what to check
The translation is written with full Vietnamese tone marks. If you burn subtitles into a video, pick a font that has every Vietnamese character, or some letters will show as boxes.
Pronouns in Vietnamese depend on age and relationship (anh, chị, em, bạn). The translation picks a neutral form; change it if you know who is talking to whom.
What people translate
