# Start a multilingual dub of a call recording

> Enqueues a multilingual dubbing job against a stored call recording. Downloads the recording media and hands it to the ElevenLabs dubbing provider, then returns the async `dubbing` handle immediately (202 Accepted). Poll `GET /voice/calls/{id}/recording/dub` to observe completion and retrieve the rendered dubbed media. Requires the `voice:write` scope. Invariant #45 holds — this only reads stored recording media and drives a media-AI provider; it never touches outbound voice/SMS signalling.
