No consent or speaker verification in the API.\n\n**Speechify API Voice Cloning.** Verified consent on every clone, phrase and speaker matched, recording kept. No cloning on the Free plan.\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### Speechify API Voice Cloning\n\n1. Create the consent challenge only when the speaker is ready. It's single use and short-lived\n2. Show the phrase as returned. Rewording it fails the match\n3. Send an `Idempotency-Key` on `POST /v1/voices` so a lost response can be replayed without spending the challenge\n4. Requests with the old `consent` field return 400 `consent_verification_required` on every API version\n5. On 429 wait for `Retry-After`, then check `error.code` to tell a rate limit from a concurrency cap\n\n## Other comparisons with Fish Audio Voice Cloning API or Speechify API Voice Cloning\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 Speechify API Voice Cloning](https://www.anchorterminal.com/compare/cartesia-voice-cloning-vs-speechify-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 Speechify API Voice Cloning](https://www.anchorterminal.com/compare/elevenlabs-voice-cloning-vs-speechify-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 Resemble AI Voice Cloning API](https://www.anchorterminal.com/compare/fish-audio-voice-cloning-vs-resemble-ai-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 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 Speechify API Voice Cloning](https://www.anchorterminal.com/compare/hume-voice-cloning-vs-speechify-voice-cloning.md)\n- [Murf Voice Cloning API vs Speechify API Voice Cloning](https://www.anchorterminal.com/compare/murf-voice-cloning-vs-speechify-voice-cloning.md)\n- [PlayHT Voice Cloning API vs Speechify API Voice Cloning](https://www.anchorterminal.com/compare/playht-voice-cloning-vs-speechify-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- [Soniox Voice Cloning vs Speechify API Voice Cloning](https://www.anchorterminal.com/compare/soniox-voice-cloning-vs-speechify-voice-cloning.md)\n- [Speechify API Voice Cloning vs Ultravox Voice Cloning](https://www.anchorterminal.com/compare/speechify-voice-cloning-vs-ultravox-voice-cloning.md)\n",
