Send a WAV, MP3 or FLAC at 24 kHz or above. A low sample rate is accepted and fails later\n3. Poll `GET /v1/speech/voice-clone-creation-status/{requestId}`, there are no webhooks\n4. Use clones only with Falcon 2 streaming. Gen2 or the non-streaming endpoint returns 400\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## Other comparisons with Murf Voice Cloning API or Soniox Voice Cloning\n\n- [Cartesia Voice Cloning API + MCP vs Murf Voice Cloning API](https://www.anchorterminal.com/compare/cartesia-voice-cloning-vs-murf-voice-cloning.md)\n- [Cartesia Voice Cloning API + MCP vs Soniox Voice Cloning](https://www.anchorterminal.com/compare/cartesia-voice-cloning-vs-soniox-voice-cloning.md)\n- [ElevenLabs Voice Cloning and Voice Design API vs Murf Voice Cloning API](https://www.anchorterminal.com/compare/elevenlabs-voice-cloning-vs-murf-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- [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 Soniox Voice Cloning](https://www.anchorterminal.com/compare/fish-audio-voice-cloning-vs-soniox-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 Soniox Voice Cloning](https://www.anchorterminal.com/compare/hume-voice-cloning-vs-soniox-voice-cloning.md)\n- [Murf Voice Cloning API vs PlayHT Voice Cloning API](https://www.anchorterminal.com/compare/murf-voice-cloning-vs-playht-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- [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- [Resemble AI Voice Cloning API vs Soniox Voice Cloning](https://www.anchorterminal.com/compare/resemble-ai-voice-cloning-vs-soniox-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- [Soniox Voice Cloning vs Ultravox Voice Cloning](https://www.anchorterminal.com/compare/soniox-voice-cloning-vs-ultravox-voice-cloning.md)\n", "meta": { "attribution": "Anchor Terminal (https://www.anchorterminal.com)", "docs": "https://www.anchorterminal.com/docs/", "generatedAt": "2026-10-05", "license": "CC-BY-4.0", "method": "https://www.anchorterminal.com/benchmark/", "methodology": "0.3", "openapi": "https://www.anchorterminal.com/openapi.json", "preview": false, "run": "2026-10-01", "runLabel": "October 2026 research run" }, "page": { "breadcrumbs": [ { "name": "Home", "url": "https://www.anchorterminal.com/" }, { "name": "Compare", "url": "https://www.anchorterminal.com/compare/" }, { "name": "Murf Voice Cloning API vs Soniox Voice Cloning", "url": "" } ], "description": "Soniox Voice Cloning has a score of 58.8 (C) against Murf Voice Cloning API's 46.5 (D).
