The voice design API is temporarily unavailable. This endpoint cannot be called at this time.
  • There is no supported request or response contract for this feature while it is withdrawn, so do not build an integration against it.
  • A call to this endpoint does not return a designed voice. It answers with the standard JSON envelope and code 10029 (The voice design API is temporarily unavailable.).
  • The previous request fields, response headers and examples have been removed from this page so that a stale link cannot be mistaken for the current contract.
A voice you already created remains fully available: it is still returned by List voices and still works with Text-to-Speech. To add a new voice, use Create a TTS voice or Create a Cover voice instead.
