  • Languages marked with - in the Recognition column cannot be used as source languages for speech recognition, but translations into these languages are supported.
  • Languages marked with - in the Translation column cannot be used as target languages for translation, but translations from these languages are supported.
  • Languages marked with - in the Voice creation / Voice cloning column cannot be used as a source for voice creation, and auto voice cloning is not available for them.

Please note that ASR quality may be lower than with the default settings for some languages.

  "pipeline": {
    "transcription": {
      "asr_model": "alpha", # <-- required
      "source_language": "auto", <--
      "detectable_languages": ["en", "fr"], <-- also for this option to work
