Video Dubbing API

Video dubbing API for 21 languages, in each speaker's own voice

Send a video and a target language and get back a dubbed file where each speaker keeps their own voice.

Available now as a local API in the desktop app. Cloud API coming soon.

What developers build with it

A dub runs transcription, translation, speaker separation and re-voicing in one pipeline. Each segment can be regenerated on its own afterwards.

  • Translated versions of a YouTube back catalog, one language per run
  • Localized training and product videos without booking voice actors
  • A separate dubbed audio track for platforms that support multiple languages

FAQ

Common Questions

21 languages, English included. GET /api/v1/dubbing/translation-languages returns the current list, so your code never sends one that isn't supported.

Yes, when you set clone_voices to true. The pipeline separates the speakers and clones each one, so the dubbed version keeps every voice distinct.

Yes. GET /api/v1/dubbing/projects/{project_id}/audio-url returns the dubbed audio track on its own, for example to upload as an extra language track on YouTube.

Yes. POST /api/v1/dubbing/projects/youtube takes the video's URL and a target language, then creates the dubbing project from it.
