## Verdicts

**Hume Octave Voice Design and Cloning + MCP.** Voice design from a natural-language description, saved with one call. Cloning over the API is Enterprise-only. Hume ends API access on 13 November 2026.

**VoiceStudio.** Local audio generation with HTTP and MCP access. Hardware and model licences vary by backend.

## Before you call either

### Hume Octave Voice Design and Cloning + MCP

1. Design with `POST /v0/tts` using an utterance `description` plus sample `text`, then save a `generation_id` with `POST /v0/tts/voices`
2. Request several generations and pick one. A saved voice can't be tuned afterwards
3. List your own voices with `GET /v0/tts/voices?provider=CUSTOM_VOICE`
4. Use `/v0/tts/file` or streaming rather than the JSON endpoint to keep base64 audio out of context
5. On E0811 back off and retry, the request was rate limited

### VoiceStudio

1. Keep the server on loopback unless network authentication has been verified.
2. Use file outputs for large audio and restrict the output directory.
3. Check the selected model licence before commercial voice use.
