## Positioning

MiniMax Speech HD is a cost-effective, multilingual text-to-speech model built for production audio generation. Reach for it when you need expressive voice synthesis at a cheap tier without sacrificing output quality.

## About

MiniMax Speech HD converts text into high-quality audio across multiple languages. It delivers expressive voice synthesis with a 5,000-token context window and is optimized for strong audio quality at a cheap tier.

On Kyma, the model runs through an OpenAI-compatible endpoint using a single API key. Every request includes automatic failover if a serving path degrades, and responses return exact billing data in usage.cost alongside an X-Kyma-Model header. Prompt caching is supported, billing repeated prefixes at 10% of the standard input rate.

The model does not support reasoning, vision, or structured outputs. It operates at a medium speed tier, making it suitable for batch processing and asynchronous audio pipelines rather than low-latency conversational applications.

## Use cases

- **Multilingual Content Narration** — Generate expressive voiceovers for videos and podcasts across multiple languages.
- **Budget Brand Voiceovers** — Produce consistent audio assets for marketing campaigns at a lower cost tier.
- **Audio Translation Workflows** — Convert localized text into natural-sounding speech for global distribution.
- **Extended Audiobook Generation** — Process long text passages into continuous audio using the full context window.

## Not ideal for

It is not suitable for real-time conversational voice agents or applications requiring sub-second audio latency.

## Pick something else when

- You need faster audio generation for interactive voice agents → `eleven-turbo-v2-5`, `minimax-speech-turbo`
- You require custom voice cloning or specialized voice design → `minimax-voice-clone`, `minimax-voice-design`
- You need premium-tier voice quality regardless of cost → `eleven-v3`
