No consent or speaker verification in the clone API.\n\n**ElevenLabs Voice Cloning and Voice Design API.** Instant clones from 1 to 2 minutes of audio on the $6 Starter plan. Instant clones rely on an attestation, not a check.\n\n## Before you call either\n\n### Cartesia Voice Cloning API + MCP\n\n1. Send `Cartesia-Version` on every call. The clone endpoint lists it as a required header\n2. Pass the speaker's recorded `language`. A clone is built from one language, add others with the accents API\n3. Keep IVC uploads under 16 MB\n4. Don't blind-retry `POST /voices/clone`. The SDK retries 429 and 5xx twice and there's no idempotency key, so check the voice list first\n5. Poll a Pro clone fine-tune until it finishes before using the voice ID\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## Other comparisons with Cartesia Voice Cloning API + MCP or ElevenLabs Voice Cloning and Voice Design API\n\n- [Cartesia Voice Cloning API + MCP vs Fish Audio Voice Cloning API](https://www.anchorterminal.com/compare/cartesia-voice-cloning-vs-fish-audio-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- [Cartesia Voice Cloning API + MCP vs Murf Voice Cloning API](https://www.anchorterminal.com/compare/cartesia-voice-cloning-vs-murf-voice-cloning.md)\n- [Cartesia Voice Cloning API + MCP vs PlayHT Voice Cloning API](https://www.anchorterminal.com/compare/cartesia-voice-cloning-vs-playht-voice-cloning.md)\n- [Cartesia Voice Cloning API + MCP vs Resemble AI Voice Cloning API](https://www.anchorterminal.com/compare/cartesia-voice-cloning-vs-resemble-ai-voice-cloning.md)\n- [Cartesia Voice Cloning API + MCP vs Soniox Voice Cloning](https://www.anchorterminal.com/compare/cartesia-voice-cloning-vs-soniox-voice-cloning.md)\n- [Cartesia Voice Cloning API + MCP vs Speechify API Voice Cloning](https://www.anchorterminal.com/compare/cartesia-voice-cloning-vs-speechify-voice-cloning.md)\n- [Cartesia Voice Cloning API + MCP vs Ultravox Voice Cloning](https://www.anchorterminal.com/compare/cartesia-voice-cloning-vs-ultravox-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 Hume Octave Voice Design and Cloning + MCP](https://www.anchorterminal.com/compare/elevenlabs-voice-cloning-vs-hume-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",
