English to Vietnamese Live Translated Captions
English meetings, trainings, and classes captioned live in Vietnamese — every tone mark intact.
Vietnamese teams on English calls and Vietnamese students in English classes often get the gist and miss the dates, quantities, and who owns the next step. Avoce turns English speech into live Vietnamese captions: the original appears first with the Vietnamese right behind it, tone marks fully intact. Online meetings go through tab audio, and the audience can scan a QR code to read on their own phones.
Nothing to install — it runs in the browser. Capture a live talk with the microphone, or caption an online meeting or video through tab audio. Register names and jargon in the glossary so the Vietnamese stays exact, let the audience scan a QR code to read captions on their own phones, and export the transcript as txt, Markdown, or srt when you’re done.
Where it shines
- English meetings with Vietnam-based teams and factories
- Staff training and onboarding in English
- English courses and lectures
What to watch for in this direction
Drop a tone mark and it becomes another word
Vietnamese uses Latin letters, but every syllable carries a tone, sometimes with two marks stacked (ế, ợ, ữ). ma, má, mà, mả, mã, and mạ are six different words, and Vietnamese without its marks reads like a sentence with the punctuation stripped — decodable, but tiring. The captions keep full diacritics; where you need care is the glossary. Enter Vietnamese colleagues’ names the way they write them (Nguyễn, not Nguyen) so the translation stays consistent.
One you, a dozen Vietnamese options
English I and you fit everyone; Vietnamese pronouns depend on age and relationship: anh, chị, em, bạn, cô, chú, ông, bà, and more. Getting one wrong is not a grammar error but a social one — rude or oddly distant. Addressing a room, the translation tends toward neutral forms such as mọi người, các bạn, or quý vị, which are safe. One-on-one, the model cannot tell who is older, so it may read as distant. For formal occasions, have a Vietnamese colleague review the key passages.
Decimal point and thousands separator are swapped
English writes 2.5 million and 10,000; Vietnamese writes 2,5 triệu and 10.000 — the comma and the point trade jobs. The translation follows Vietnamese convention, which is right for the Vietnamese reader, but someone used to English can misread a digit when comparing. For quotes, output figures, and budgets, keep the original line on so both sides can check.
Three steps to start — nothing to install.
Put these in the glossary first
The glossary applies to both recognition and translation: terms you register up front stop the model re-guessing a rendering every time.
- Names of Vietnamese colleagues and speakers, written as they write them, diacritics included
- Company names, product names, and project code names, marked to stay in English
- English words Vietnamese workplaces use as-is, noting whether to translate them (deadline, KPI, meeting)
- Vietnamese place names for factories and branch offices

Common questions
Northern or Southern Vietnamese?
Standard written Vietnamese, which readers from the north and the south both follow. The regional differences sit mostly in accent and a handful of everyday words; if your team has a fixed term for something, put it in the glossary.
Will the tone marks show up properly on phones?
Yes. Vietnamese is standard Unicode and current phone browsers display it correctly. The audience scans a QR code to read — no app to install.
Does it work on calls with a team in Vietnam?
Yes. Tab audio captures the meeting tab directly, which covers Google Meet and Zoom on the web. Share the room’s QR code with your Vietnamese colleagues and they read Vietnamese captions on their own devices.
