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
