AI voice dubbing with cloned voices

The dub is spoken in a voice built from your own speaker's audio — not a stock narrator reading a translation.

Dubbing that keeps the voice, not just the words

A translation read by a generic narrator changes who the video is from. This tool builds a voice for each speaker it detects in the first 60 seconds and uses that voice for their lines, so a two-person conversation still sounds like two people and a founder's video still sounds like the founder.

What people use it for

Voice is most of what people recognize about a video. Replacing it is usually the thing that makes a dub feel wrong.

What happens to your video

Your upload is deleted as soon as we have trimmed the first minute, and the dubbed result is deleted one hour after it is ready. Voice clones are created for this run only and removed when it finishes. Nothing is kept for training.

How the voice is built

We isolate each speaker's audio from the clip and build a voice model from it, then use that model for their translated lines. It is created for this run and deleted when the run finishes.

Videos with several speakers

Speakers are separated automatically and each gets their own voice. Interviews and two-host formats keep their back-and-forth instead of collapsing into one narrator. In a 60-second clip, a speaker with only a few words may not have enough audio to clone well — that is a limit of the sample, not of the model.

Getting a good clone

Clean, isolated speech makes a noticeably better voice than speech buried under music. If you can, upload a version before the music was mixed in.

Questions

How much of my video gets dubbed?

The first 60 seconds. You can upload a video of any length — we trim it before anything else runs, so a two-hour file works fine and only the opening minute is dubbed.

Which languages can I dub into?

More than 70, including Spanish, French, German, Portuguese, Japanese, Korean, Hindi, Arabic and Mandarin. Pick the target language before you start.

Does it keep the original speaker's voice?

Yes. Every speaker we detect gets their own cloned voice, so the dub sounds like the people in your video rather than a stock narrator.

Do you keep my video?

No. The file you upload is deleted as soon as the first 60 seconds are trimmed, and the dubbed result is deleted one hour later. Voice clones exist only for the length of the run.

Why does the timing drift on some lines?

A translated sentence is rarely the same length as the original, so the dub has to be reshaped to fit each speaker's timing. The free tool does one pass of that; a paid project does several, which is why the sync is tighter.

What does an account add?

Full-length videos instead of 60 seconds, no watermark, lip sync, a voice library, editable translations, and subtitle export.
