Reference: https://elevenlabs.io/docs/api-reference/legacy/dubbing/create ## Servers - `https://api.elevenlabs.io` (Production, default) - `https://api.us.elevenlabs.io` (Production US) - `https://api.eu.residency.elevenlabs.io` (Production EU) - `https://api.in.residency.elevenlabs.io` (Production India) - `https://api.sg.residency.elevenlabs.io` (Production Singapore) ## Request ### Body (multipart/form-data) This endpoint expects a multipart form with multiple files. - `file` (file, optional) — A list of file paths to audio recordings intended for voice cloning - `csv_file` (file, optional) — CSV file containing transcription/translation metadata - `foreground_audio_file` (file, optional) — For use only with csv input - `background_audio_file` (file, optional) — For use only with csv input - `name` (string, optional) — Name of the dubbing project. - `source_url` (string, optional) — URL of the source video/audio file. - `source_lang` (string, optional) — Source language. Expects a valid iso639-1 or iso639-3 language code. - `target_lang` (string, required) — The Target language to dub the content into. Expects a valid iso639-1 or iso639-3 language code. - `target_accent` (string, optional) — [Experimental] An accent to apply when selecting voices from the library and to use to inform translation of the dialect to prefer. - `num_speakers` (integer, optional) — Number of speakers to use for the dubbing. Set to 0 to automatically detect the number of speakers - `watermark` (boolean, optional) — Whether to apply watermark to the output video. - `start_time` (integer, optional) — Start time of the source video/audio file. - `end_time` (integer, optional) — End time of the source video/audio file. - `highest_resolution` (boolean, optional) — Whether to use the highest resolution available. - `drop_background_audio` (boolean, optional) — An advanced setting. Whether to drop background audio from the final dub. This can improve dub quality where it's known that audio shouldn't have a background track such as for speeches or monologues. - `use_profanity_filter` (boolean, optional) — [BETA] Whether transcripts should have profanities censored with the words '[censored]' - `dubbing_studio` (boolean, optional) — Whether to prepare dub for edits in dubbing studio or edits as a dubbing resource. - `disable_voice_cloning` (boolean, optional) — Instead of using a voice clone in dubbing, use a similar voice from the ElevenLabs Voice Library. Voices used from the library will contribute towards a workspace's custom voices limit, and if there aren't enough available slots the dub will fail. Using this feature requires the caller to have the 'add_voice_from_voice_library' permission on their workspace to access new voices. - `mode` (enum, optional) — The mode in which to run this Dubbing job. Defaults to automatic, use manual if specifically providing a CSV transcript to use. Note that manual mode is experimental and production use is strongly discouraged. - `csv_fps` (double, optional) — Frames per second to use when parsing a CSV file for dubbing. If not provided, FPS will be inferred from timecodes. ## Response ### 200 Successful Response - `dubbing_id` (string, required) — The ID of the dubbing project. - `expected_duration_sec` (double, required) — The expected duration of the dubbing project in seconds. ## Errors ### 422 Unprocessable Entity Error Validation Error - `detail` (list of ValidationError, optional) ## Types ### ValidationError - `loc` (list of ValidationErrorLocItems, required) - `msg` (string, required) - `type` (string, required) ### ValidationErrorLocItems ## Examples **Request** ```json { "background_audio_file": ">", "csv_file": ">", "file": ">", "foreground_audio_file": ">", "target_lang": "string" } ``` **Response** ```json { "dubbing_id": "21m00Tcm4TlvDq8ikWAM", "expected_duration_sec": 127.5 } ``` **SDK Code** ```python import requests url = "https://api.elevenlabs.io/v1/dubbing" files = { "background_audio_file": "open('', 'rb')", "csv_file": "open('', 'rb')", "file": "open('', 'rb')", "foreground_audio_file": "open('', 'rb')" } payload = { "csv_fps": , "disable_voice_cloning": , "drop_background_audio": , "dubbing_studio": , "end_time": , "highest_resolution": , "mode": , "name": , "num_speakers": , "source_lang": , "source_url": , "start_time": , "target_accent": , "target_lang": "string", "use_profanity_filter": , "watermark": } response = requests.post(url, data=payload, files=files) print(response.json()) ``` ```javascript const url = 'https://api.elevenlabs.io/v1/dubbing';
