<Warning>
  Transcription provided by external service partners (marked with ⎋) cannot yet auto-detect the source language,
  which you must therefore specify explicitly.
</Warning>

To retrieve supported languages and feature availability programmatically, call [`GET /v3/languages?resource=voice`](/docs/languages/using-the-languages-api) and check for the `transcription` and `translated_speech` feature keys. The `external` flag on these features indicates if they are provided by an external service partner.

For audio format support and session limits, see [Voice API Requirements](/docs/voice/voice-api-requirements).
