MiniMax Voice Clone

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.

Specs

Field	Value

Pricing

	Cost
Per cloned voice	$2.10 flat (one-time)

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.
