Cloning needs individual or enterprise account verification, the terms and privacy policy could not be read without a browser, and no statement on training with uploaded voice audio was found in the docs.\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### MiniMax Voice Clone and Voice Design\n\n1. Upload the sample to `POST /v1/files/upload` with `purpose=voice_clone`, then pass the integer `file_id` and a new `voice_id` of 8 to 256 characters to `POST /v1/voice_clone`\n2. Synthesise once with T2A within 7 days or the voice is deleted. A preview inside the clone call does not count\n3. Read `base_resp.status_code` on every response. Errors such as 2038 (no cloning permission) and 2039 (duplicate `voice_id`) arrive in the body\n4. Voice design returns `trial_audio` as hex in the JSON body. Write it to a file and keep it out of the model context\n5. Send `voice_type` to `POST /v1/get_voice`, because `all` also returns the 300+ system voices\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## Questions\n\n### Which is better for AI agents, MiniMax Voice Clone and Voice Design or Ultravox Voice Cloning?\n\nMiniMax Voice Clone and Voice Design scores 53.1 (D) on agent readiness against Ultravox Voice Cloning's 40.8 (E), and leads in 6 of 7 scored categories. Ultravox Voice Cloning leads on payments \u0026 pricing.\n\n### Do MiniMax Voice Clone and Voice Design and Ultravox Voice Cloning need an API key?\n\nBoth need an API key.\n\n### Can an agent call MiniMax Voice Clone and Voice Design and Ultravox Voice Cloning without installing anything?\n\nYes.
