Cloning API only on Business ($1,000 a month) and Enterprise.\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### 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### 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 Resemble AI Voice Cloning API or Speechify API Voice Cloning\n\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 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 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 Speechify API Voice Cloning](https://www.anchorterminal.com/compare/elevenlabs-voice-cloning-vs-speechify-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 Speechify API Voice Cloning](https://www.anchorterminal.com/compare/fish-audio-voice-cloning-vs-speechify-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 Speechify API Voice Cloning](https://www.anchorterminal.com/compare/hume-voice-cloning-vs-speechify-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- [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 Resemble AI Voice Cloning API](https://www.anchorterminal.com/compare/playht-voice-cloning-vs-resemble-ai-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 Soniox Voice Cloning](https://www.anchorterminal.com/compare/resemble-ai-voice-cloning-vs-soniox-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- [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",
