AI voice cloning for multilingual dubbing
TH-Labs clones a speaker's voice from about three seconds of clean audio, then uses it to speak their words in 40+ languages — so the audience hears the same person, not a stranger.
Why the voice matters
A voice carries identity. When a dub swaps it for a generic narrator, the audience loses the person they came to watch. Voice cloning keeps the timbre and character of the original speaker in every language.
Built for dubbing
The cloned voice stays consistent across a whole video and across languages. In interviews and panels, each detected speaker gets their own clone. Lip sync matches mouth movement to the new track, and subtitles are exported from the same run.
