ElevenLabs Dubbing

Dub audio or video into other languages while preserving the original speakers' voices. Create a project from a file or URL, review and edit the source transcript, add one or more target languages, refine translations per segment, and regenerate outputs.

Important: Use the Dubbing Projects API — elevenlabs.dubbing.project.* in the SDKs, or the /v1/dubbing/project REST endpoints. Do not use the legacy v1 dubbing surface (client.dubbing.create(), client.dubbing.get(), client.dubbing.audio.get(), or bare /v1/dubbing routes) — that is the older dubbing API, now under Legacy in the API reference.

Setup: See Installation Guide. REST base URL is https://api.elevenlabs.io with your API key in the xi-api-key header; the SDKs read ELEVENLABS_API_KEY automatically.

Concepts

Concept	Meaning
Project	One source of media (file or URL) plus its source transcript. Prepared (transcribed) once, then rests in `ready` while you add languages.
Source transcript	Editable segments (text, speaker, timing) transcribed from the source. The single source of truth every language is translated from.
Language (target)	One dubbed output language. Each has its own transcript (source segments + a translation per segment) and its own dubbed audio output.
Revisions	Independent monotonic counters. The project's `revision` bumps on source-transcript edits; a language's `revision` bumps on translation edits or source edits that affect it. A language's `output_revision` is the revision its current audio was generated from — when it's behind `revision`, the output is out of date.

Recommended order of operations: finalize the source transcript before adding any languages. Translations are produced from the source, so correcting the source first means every language starts from the right text — editing the source after a language completes marks it stale and requires a (charged) regeneration.
