Overview

minimax-voice-clone is a voice-cloning service, not a direct TTS model. Upload reference audio of someone speaking (10 seconds to 5 minutes) and get back a voice_id. That ID then becomes a usable voice on /v1/audio/speech with any MiniMax voice model. Right for brand voice cloning when you have voice talent, character voices for games and animation, or custom narrator profiles for podcasts.

The voice_id is then free to use in /v1/audio/speech — only the speech calls themselves bill at MiniMax’s per-character rate.

​
Use this when

  • You have voice talent and want their voice usable across all your TTS workflows.
  • You’re building a character cast for a game or animation.
  • You want a single brand voice spanning multiple languages and use cases.

​
Pick something else when

  • You don’t have a reference recording → minimax-voice-design ($4.20/voice from text description).
  • You’re fine with stock MiniMax voices → skip cloning, browse system voices via GET /v1/audio/voices and use directly.

Example

# Step 1: clone the voice
curl -X POST https://kymaapi.com/v1/audio/voice-clone \
  -H "Authorization: Bearer $KYMA_API_KEY" \
  -F file=@reference.mp3 \
  -F name="brand-narrator"
# → { "voice_id": "kyma_3f8e2a1b4c9d7e60", ... }

# Step 2: use the voice
curl -X POST https://kymaapi.com/v1/audio/speech \
  -H "Authorization: Bearer $KYMA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "minimax-speech-hd",
    "input": "Welcome to the show.",
    "voice_id": "kyma_3f8e2a1b4c9d7e60"
  }' \
  --output intro.mp3

​
Ownership

Cloned voice IDs are gated per Kyma user. If user A passes user B’s voice_id to /v1/audio/speech, the request returns 403 voice_not_owned.
