AI dubbing that keeps your voice
TH-Labs is an AI dubbing system: upload a video, pick the languages, and get back the same speaker, speaking fluently in each of them — with their own voice and matched lip movement.
What AI dubbing does
Traditional dubbing needs a translator, a voice actor per language and a studio session for every update. AI dubbing replaces that chain with one pipeline: speech recognition transcribes the original, machine translation carries the meaning into the target language, and a cloned voice speaks the result in the original speaker's timbre.
The result is a dub that sounds like the person on screen rather than a stranger reading a script — which is the difference between an audience that stays and one that switches off.
Why TH-Labs
Voice cloning from about three seconds of reference audio, kept consistent across every line. Lip sync matched to the dubbed track. Multi-speaker detection, so an interview or a panel keeps each voice distinct. Subtitle and caption export alongside the audio.
Pre-recorded video runs faster than real time — a ten-minute file is usually ready in a few minutes — and live streams can be dubbed continuously at roughly two seconds of delay.
Who uses AI dubbing
Creators taking a YouTube channel into new markets, schools and online courses reaching students in their own language, companies localising product videos and training, and broadcasters running live events for a multilingual audience. Developers can do all of it programmatically through the API.
