Via REST: `GET /v1/dubbing/project/{project_id}/transcript`, then `PATCH .../transcript/segment/{segment_id}` with only the changed fields:

```bash
curl -X PATCH "https://api.elevenlabs.io/v1/dubbing/project/{project_id}/transcript/segment/{segment_id}" \
  -H "xi-api-key: $ELEVENLABS_API_KEY" -H "Content-Type: application/json" \

Via REST: `PATCH /v1/dubbing/project/{project_id}/language/{language_id}/transcript/segment/{segment_id}` with `{"translation": "..."}`, then `POST .../language/{language_id}/transcript/regenerate` (returns `202 Accepted`).

A translation edit affects only that language. After the edit, a `completed` language becomes `stale` — it keeps serving its previous output until you regenerate. Poll until `completed`; `output_revision` then equals `revision` and `outputs.lossless_audio` reflects the current transcript.
