## Which one, for what

### Hume Octave Voice Design and Cloning + MCP (C)

Good for: Designing a voice from a description, and for teams already on EVI.

Ahead on:
- Schema & documentation, 87 against 78
- Agent ergonomics, 75 against 56
- Payments & pricing, 30 against 20
- Maintenance & community, 45 against 38

Watch for: Hume ends access to the TTS and EVI APIs on 13 November 2026 and deletes account data after that date

### MiniMax Voice Clone and Voice Design (D)

Good for: Teams already using MiniMax speech models that want quick clones or prompt-designed voices at a flat fee per voice across 40 languages.

Ahead on:
- Reliability, 70 against 58
- Security & auth, 39 against 23

Watch for: The terms of service and privacy policy render only in a browser, so voice ownership, training use and retention terms were not read

## 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.

**MiniMax Voice Clone and Voice Design.** Typed OpenAPI files, published prices of $1.50 a cloned voice and $3 a designed voice, and optional transcript and watermark checks. 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.

## 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

### MiniMax Voice Clone and Voice Design

1. 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`
2. Synthesise once with T2A within 7 days or the voice is deleted. A preview inside the clone call does not count
3. Read `base_resp.status_code` on every response. Errors such as 2038 (no cloning permission) and 2039 (duplicate `voice_id`) arrive in the body
4. Voice design returns `trial_audio` as hex in the JSON body. Write it to a file and keep it out of the model context
5. Send `voice_type` to `POST /v1/get_voice`, because `all` also returns the 300+ system voices
