## Positioning

MiniMax Speech Turbo is a low-latency, multilingual text-to-speech model optimized for high-throughput and real-time conversational workloads. Reach for it when you need fast, cost-efficient audio generation for voice agents or bulk narration.

## About

MiniMax Speech Turbo converts text input into audio output with a focus on speed and efficiency. It supports multiple languages and operates in the cheap cost tier and fast speed tier, making it suitable for applications that prioritize low latency and high request volume over studio-grade fidelity.

On Kyma, the model is accessible via an OpenAI-compatible endpoint using a single API key. It supports prompt caching, which applies a 90% discount to repeated input prefixes, and includes automatic failover to reroute requests if a serving path degrades. Responses return exact billing metrics in the usage.cost field and report the active model in the X-Kyma-Model header.

The endpoint does not support reasoning, vision, or structured outputs, and it is strictly a speech generation interface. It is designed for scalable deployments where consistent throughput and fast delivery are the primary requirements.

## Use cases

- **Real-time voice agents** — Generates rapid audio responses for interactive conversational systems.
- **Bulk narration pipelines** — Processes large volumes of text into speech efficiently.
- **Conversational AI backends** — Delivers fast, multilingual audio output for chat and voice assistants.
- **Scalable text to speech** — Handles concurrent requests efficiently for high-volume audio generation.

## Not ideal for

Do not use this model when you require studio-quality voice fidelity, complex audio editing, or structured JSON outputs.

## Pick something else when

- You need higher voice fidelity → `eleven-v3`, `minimax-speech-hd`
- You need music or sound effect generation → `elevenlabs-music`, `minimax-music-pro`
- You need voice cloning or custom voice design → `minimax-voice-clone`, `minimax-voice-design`
