Dub any video into 40+ languages
Online video dubbing with AI. Upload a file and TH-Labs returns a dubbed version in every language you choose — the speaker's own voice, translated, with lip sync to match.
Video dubbing without a studio
Dubbing a video used to mean booking voice actors for every language and re-recording whenever the edit changed. With TH-Labs the whole job runs in the browser: the original speech is transcribed, translated and re-voiced automatically, and the new track is laid back over the picture.
Because the voice is cloned from the original, viewers hear the same person in their own language — not a generic synthetic narrator.
Built for real footage
Interviews, podcasts and panels are handled with multi-speaker detection, so each person keeps their own voice. Lip sync aligns mouth movement to the dubbed audio. Subtitles and captions can be exported in every target language from the same run.
A ten-minute video is usually ready in a few minutes; live streams are dubbed in real time at about two seconds of delay.
