Use tool ↗About Speechlab
Speechlab runs the whole dubbing chain in a browser: upload video or audio, get a transcript with speakers separated, correct the translation against a waveform, then render dubbed audio in any of 50+ languages. Voices can be cloned from the original speakers or swapped for native stock voices, and one segment can be re-dubbed without reprocessing the file. The company was incubated at Andrew Ng's AI Fund and runs a distributed team. Selling is metered rather than per seat: the free tier is capped at two projects, Pro costs $0.60 per minute of media processed, and API access is reserved for Pro and Enterprise.

Pros & cons of Speechlab
A dubbing workbench rather than a one-click button: you get a diarised transcript, an editable translation and per-speaker voice assignment before anything renders. That review loop is the reason to pick it over cheaper tools, and the per-minute meter is the reason to price a project before uploading a back catalogue.
Pros
- Segment-level re-dub: fixing one line does not force a full re-render
- Speaker diarisation with a separate voice assigned per speaker
- Voice cloning carries the original speaker into the target language
- Transcript and translation editor tied to the waveform, so timing is fixable by hand
Cons
- Per-minute billing scales badly on long libraries
- Free tier of two projects is too small to judge quality on real work
- Enterprise pricing is quote-only, so budgeting needs a sales call
- API is gated behind Pro and above
Best for
- publishers localising an existing library
- course and podcast teams shipping multi-language versions
- workflows that need a human check between translation and render
Not for
- one-off social clips where a flat monthly plan is cheaper
- languages outside the supported 50+
Watch out: Pro is $0.60 per media minute — budget by hours of content, not by number of users.
