No consent capture or speaker verification, and the terms say so.\n\n**Ultravox Voice Cloning.** One multipart request with a 30 to 60 second sample. No consent or speaker verification, only a warranty in the terms.\n\n## Before you call either\n\n### Soniox Voice Cloning\n\n1. Poll the voice until the target model's status is `ready` before using it in TTS\n2. On `voice_not_prepared` call recompute, don't retry the TTS request\n3. Don't retry `voice_failed` even though it's a 503. Create a new voice from a better clip\n4. Use a key from the project that owns the voice, voices are per project\n5. Keep the clip under 2 minutes and 35 MB, longer fails with `voice_audio_too_long`\n\n### Ultravox Voice Cloning\n\n1. Send a single clean, single-speaker MP3 or WAV of 30 to 60 seconds, 10 MB at most\n2. Expect one clone per account unless support raises it, whatever the plan page says\n3. Test the voice in the Playground before putting it on a live agent\n4. Get the speaker's written consent first, the terms require it and Ultravox doesn't check\n\n## Other comparisons with Soniox Voice Cloning or Ultravox Voice Cloning\n\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 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 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 Ultravox Voice Cloning](https://www.anchorterminal.com/compare/elevenlabs-voice-cloning-vs-ultravox-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 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 Ultravox Voice Cloning](https://www.anchorterminal.com/compare/hume-voice-cloning-vs-ultravox-voice-cloning.md)\n- [Murf Voice Cloning API vs Soniox Voice Cloning](https://www.anchorterminal.com/compare/murf-voice-cloning-vs-soniox-voice-cloning.md)\n- [Murf Voice Cloning API vs Ultravox Voice Cloning](https://www.anchorterminal.com/compare/murf-voice-cloning-vs-ultravox-voice-cloning.md)\n- [PlayHT Voice Cloning API vs Soniox Voice Cloning](https://www.anchorterminal.com/compare/playht-voice-cloning-vs-soniox-voice-cloning.md)\n- [PlayHT Voice Cloning API vs Ultravox Voice Cloning](https://www.anchorterminal.com/compare/playht-voice-cloning-vs-ultravox-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",
