## Positioning

MiniMax Voice Design generates synthetic voice profiles from natural-language descriptions without requiring reference audio. Use it when you need custom vocal identities for branding, characters, or personas but lack audio samples.

## About

MiniMax Voice Design creates a synthesized voice profile from a text prompt. It returns a voice_id that works with any MiniMax HD or Turbo speech endpoint. The model operates on a per-call basis with a flat charge for each designed voice.

On Kyma, the model runs through the standard OpenAI-compatible base URL using a single API key. Every request includes automatic failover if a serving path degrades, and responses report exact costs in usage.cost alongside the active model in the X-Kyma-Model header. Prompt caching applies to repeated prefixes at a 10% rate, and new accounts include a $0.50 signup credit.

The model accepts text input and outputs audio metadata rather than continuous speech streams. It does not support reasoning, vision, or structured outputs, and operates with a 1,000-token context window. It is optimized for voice design rather than direct text-to-speech generation.

## Use cases

- **Brand Voice Creation** — Generate consistent synthetic voices for corporate branding without hiring voice actors.
- **Fictional Character Voices** — Design unique vocal profiles for game or narrative characters using text prompts.
- **Persona Voice Generation** — Create custom speaker identities from descriptive text when reference audio is unavailable.
- **Rapid Audio Prototyping** — Test different vocal styles during product development using a flat per-call workflow.

## Not ideal for

Do not use this model to clone existing voices from audio samples or to generate continuous long-form speech directly.

## Pick something else when

- You need to clone a real voice from audio samples → `eleven-turbo-v2-5`, `minimax-voice-clone`
- You need direct text-to-speech generation → `minimax-speech-hd`, `minimax-speech-turbo`
- You need multilingual speech with existing voice IDs → `eleven-multilingual-v2`, `eleven-v3`
