Instant clones rely on an attestation, not a check.\n\n**Hume Octave Voice Design and Cloning + MCP.** Voice design from a natural-language description, saved with one call. Cloning over the API is Enterprise-only.\n\n## Before you call either\n\n### ElevenLabs Voice Cloning and Voice Design API\n\n1. Keep the source samples. A clone can't be downloaded and re-cloning sounds slightly different\n2. Check `requires_verification` in the create response before using the voice ID\n3. List your own clones with `GET /v2/voices?category=cloned` instead of paging the whole library\n4. On `system_busy` retry with backoff. On `too_many_concurrent_requests` queue instead, the plan cap won't lift\n5. PVC is asynchronous. Create, add samples, verify, train, then poll `fine_tuning_state`\n\n### Hume Octave Voice Design and Cloning + MCP\n\n1. Design with `POST /v0/tts` using an utterance `description` plus sample `text`, then save a `generation_id` with `POST /v0/tts/voices`\n2. Request several generations and pick one. A saved voice can't be tuned afterwards\n3. List your own voices with `GET /v0/tts/voices?provider=CUSTOM_VOICE`\n4. Use `/v0/tts/file` or streaming rather than the JSON endpoint to keep base64 audio out of context\n5. On E0811 back off and retry, the request was rate limited\n\n## Other comparisons with ElevenLabs Voice Cloning and Voice Design API or Hume Octave Voice Design and Cloning + MCP\n\n- [Cartesia Voice Cloning API + MCP vs ElevenLabs Voice Cloning and Voice Design API](https://www.anchorterminal.com/compare/cartesia-voice-cloning-vs-elevenlabs-voice-cloning.md)\n- [Cartesia Voice Cloning API + MCP vs Hume Octave Voice Design and Cloning + MCP](https://www.anchorterminal.com/compare/cartesia-voice-cloning-vs-hume-voice-cloning.md)\n- [ElevenLabs Voice Cloning and Voice Design API vs Fish Audio Voice Cloning API](https://www.anchorterminal.com/compare/elevenlabs-voice-cloning-vs-fish-audio-voice-cloning.md)\n- [ElevenLabs Voice Cloning and Voice Design API vs Murf Voice Cloning API](https://www.anchorterminal.com/compare/elevenlabs-voice-cloning-vs-murf-voice-cloning.md)\n- [ElevenLabs Voice Cloning and Voice Design API vs PlayHT Voice Cloning API](https://www.anchorterminal.com/compare/elevenlabs-voice-cloning-vs-playht-voice-cloning.md)\n- [ElevenLabs Voice Cloning and Voice Design API vs Resemble AI Voice Cloning API](https://www.anchorterminal.com/compare/elevenlabs-voice-cloning-vs-resemble-ai-voice-cloning.md)\n- [ElevenLabs Voice Cloning and Voice Design API vs Soniox Voice Cloning](https://www.anchorterminal.com/compare/elevenlabs-voice-cloning-vs-soniox-voice-cloning.md)\n- [ElevenLabs Voice Cloning and Voice Design API vs Speechify API Voice Cloning](https://www.anchorterminal.com/compare/elevenlabs-voice-cloning-vs-speechify-voice-cloning.md)\n- [ElevenLabs Voice Cloning and Voice Design API vs Ultravox Voice Cloning](https://www.anchorterminal.com/compare/elevenlabs-voice-cloning-vs-ultravox-voice-cloning.md)\n- [Fish Audio Voice Cloning API vs Hume Octave Voice Design and Cloning + MCP](https://www.anchorterminal.com/compare/fish-audio-voice-cloning-vs-hume-voice-cloning.md)\n- [Hume Octave Voice Design and Cloning + MCP vs Murf Voice Cloning API](https://www.anchorterminal.com/compare/hume-voice-cloning-vs-murf-voice-cloning.md)\n- [Hume Octave Voice Design and Cloning + MCP vs PlayHT Voice Cloning API](https://www.anchorterminal.com/compare/hume-voice-cloning-vs-playht-voice-cloning.md)\n- [Hume Octave Voice Design and Cloning + MCP vs Resemble AI Voice Cloning API](https://www.anchorterminal.com/compare/hume-voice-cloning-vs-resemble-ai-voice-cloning.md)\n- [Hume Octave Voice Design and Cloning + MCP vs Soniox Voice Cloning](https://www.anchorterminal.com/compare/hume-voice-cloning-vs-soniox-voice-cloning.md)\n- [Hume Octave Voice Design and Cloning + MCP vs Speechify API Voice Cloning](https://www.anchorterminal.com/compare/hume-voice-cloning-vs-speechify-voice-cloning.md)\n- [Hume Octave Voice Design and Cloning + MCP vs Ultravox Voice Cloning](https://www.anchorterminal.com/compare/hume-voice-cloning-vs-ultravox-voice-cloning.md)\n",
