Vibe 코딩 중에 resemble.ai chatterbox-multilingual-tts 모델을 사용하려고 시도하던 중, AI는 제 API 키가 한국어 음성에 대해 활성화되지 않았다고 밝혔습니다. 예제 코드를 실행했을 때, 여전히 API 키에 대해 한국어 음성이 활성화되지 않았습니다. 어떻게 해결할 수 있습니까? 제 API 키는 최근에 생성되었으며 만료까지 11개월이 남아 있습니다. 다음은 코덱스에서 제공하는 오류 메시지입니다.

Summary

  • function-id used: ddacc747-1269-4fab-bfd9-8f593dead106
  • Voice used: Chatterbox-Multilingual.ko-KR.Male
  • Server: grpc.nvcf.nvidia.com:443
  • Outcome: NOT_FOUND
  • Meaning: the requested function is not available for this account/key

Notes

  • The API key was intentionally redacted for sharing.
  • This error happened before any audio file could be generated.
  • The account appears to have Magpie TTS functions available, but not Chatterbox.
