We found no earlier public notice. An upgrade path exists, and we can't see whether customers were told privately, so a small deduction. https://www.resemble.ai/changelog and https://docs.resemble.ai/getting-started/model-versions"

Cloning over the API is Enterprise-only.\n\n**Resemble AI Voice Cloning API.** Rapid clones from 10 seconds of audio, ready in under a minute. Cloning API only on Business ($1,000 a month) and Enterprise.\n\n## Before you call either\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### 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 Hume Octave Voice Design and Cloning + MCP or Resemble AI Voice Cloning API\n\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 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 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 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 Resemble AI Voice Cloning API](https://www.anchorterminal.com/compare/fish-audio-voice-cloning-vs-resemble-ai-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 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- [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",
