Cloning API only on Business ($1,000 a month) and Enterprise.\n\n## Before you call either\n\n### Fish Audio Voice Cloning API\n\n1. Send 2 or 3 clean single-speaker clips with matching `texts`, or the API runs ASR on them\n2. Pass the model `_id` as `reference_id` in TTS. Check `state` before relying on it\n3. For one-off voices send `references` inline to `/v1/tts` instead of creating a model\n4. Send the `model: voice-design-1` header on voice design calls\n5. Keep concurrency at 5 until prepaid spend passes $100, there's no documented retry guidance\n\n### Resemble AI Voice Cloning API\n\n1. Create the voice, upload recordings or pass `dataset_url`, then call `/build`. Nothing trains until you do\n2. Set `callback_uri` rather than polling for `status` to reach `finished`\n3. Expect a rapid clone. Since 2026-06-30 API-created voices default to rapid, and create-voice has no field to pick another type\n4. Upgrade any voice on a pre-Ultra model before synthesis, since those voices can no longer generate audio\n5. Check `success` in every response body, log the request ID, and stay under 40 requests a second per token with your own backoff\n\n## Other comparisons with Fish Audio Voice Cloning API or Resemble AI Voice Cloning 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 Resemble AI Voice Cloning API](https://www.anchorterminal.com/compare/cartesia-voice-cloning-vs-resemble-ai-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 Resemble AI Voice Cloning API](https://www.anchorterminal.com/compare/elevenlabs-voice-cloning-vs-resemble-ai-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- [Fish Audio Voice Cloning API vs Murf Voice Cloning API](https://www.anchorterminal.com/compare/fish-audio-voice-cloning-vs-murf-voice-cloning.md)\n- [Fish Audio Voice Cloning API vs PlayHT Voice Cloning API](https://www.anchorterminal.com/compare/fish-audio-voice-cloning-vs-playht-voice-cloning.md)\n- [Fish Audio Voice Cloning API vs Soniox Voice Cloning](https://www.anchorterminal.com/compare/fish-audio-voice-cloning-vs-soniox-voice-cloning.md)\n- [Fish Audio Voice Cloning API vs Speechify API Voice Cloning](https://www.anchorterminal.com/compare/fish-audio-voice-cloning-vs-speechify-voice-cloning.md)\n- [Fish Audio Voice Cloning API vs Ultravox Voice Cloning](https://www.anchorterminal.com/compare/fish-audio-voice-cloning-vs-ultravox-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- [Murf Voice Cloning API vs Resemble AI Voice Cloning API](https://www.anchorterminal.com/compare/murf-voice-cloning-vs-resemble-ai-voice-cloning.md)\n- [PlayHT Voice Cloning API vs Resemble AI Voice Cloning API](https://www.anchorterminal.com/compare/playht-voice-cloning-vs-resemble-ai-voice-cloning.md)\n- [Resemble AI Voice Cloning API vs Soniox Voice Cloning](https://www.anchorterminal.com/compare/resemble-ai-voice-cloning-vs-soniox-voice-cloning.md)\n- [Resemble AI Voice Cloning API vs Speechify API Voice Cloning](https://www.anchorterminal.com/compare/resemble-ai-voice-cloning-vs-speechify-voice-cloning.md)\n- [Resemble AI Voice Cloning API vs Ultravox Voice Cloning](https://www.anchorterminal.com/compare/resemble-ai-voice-cloning-vs-ultravox-voice-cloning.md)\n",
