Hardware and model licences vary by backend.\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### VoiceStudio\n\n1. Keep the server on loopback unless network authentication has been verified.\n2. Use file outputs for large audio and restrict the output directory.\n3. Check the selected model licence before commercial voice use.\n\n## Tutorials\n\n- [Create and preview a voice in Hume](https://www.anchorterminal.com/tutorials/hume-voice-cloning/), for Hume Octave Voice Design and Cloning + MCP\n\n## Questions\n\n### Which is better for AI agents, Hume Octave Voice Design and Cloning + MCP or VoiceStudio?\n\nHume Octave Voice Design and Cloning + MCP scores 54.6 (C) on agent readiness against VoiceStudio's 46.2 (D), and leads in 4 of 7 scored categories.
