The voice design API is temporarily unavailable, including this save endpoint. It cannot be called at this time.
  • Saving a designed voice is unavailable, because a designed voice cannot be created while the feature is withdrawn.
  • A call to this endpoint answers with the standard JSON envelope and code 10029 (The voice design API is temporarily unavailable.).
  • The previous request fields and examples have been removed from this page so that a stale link cannot be mistaken for the current contract.
A voice you already saved 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.
