Talk2Viet AI translates and dubs YouTube videos with a natural Vietnamese voice — one click. No sign-up, no data stored.
No subtitle tabs, no translators. Talk2Viet lives inside YouTube and dubs in real time.
Any video with captions — including auto-generated ones in 30+ languages.
A red-orange button appears in the YouTube controls. Tap it to start the dubbing pipeline.
Neural voice audio streams in sync with the video within ~5 seconds. Change voice or speed any time from the popup.
Generic translators butcher domain words. Talk2Viet classifies the video first, then uses a domain-specific prompt so terms stay correct.
News, gaming, education, tech, lifestyle, sports, kids, podcast — each domain has its own translation rules. Tech videos keep "deploy", "API", "model" untouched.
You hear the first sentence in ~5 seconds. The rest streams in priority order around where you're watching.
Once one viewer translates a video, every subsequent viewer gets it instantly. Your videos warm the cache for the community.
Microsoft Edge's neural Vietnamese voices read the translation aloud — natural pitch, real intonation, multiple voice choices.
Scrub to minute 12 and translation re-prioritises around your current time so audio is ready when you need it.
Subtitle text for translation. That's it — no watch history, no browsing data, nothing outside the YouTube page you're on.
Install the Chrome extension and open any YouTube video to hear it in Vietnamese.
