Agent guidance:
- Use this page when the user is asking about this specific route or model capability.
- Preserve endpoint paths, JSON keys, model IDs, and placeholder values exactly.
- Treat examples such as `sk-***`, `{BASE_URL}`, and `task_xxx` as safe placeholders, not real secrets.

## Page Markdown

This document explains how to use MiniMax voiceCapability, voice list, Voice CloningandVoice Design.

If you only need to generate speech from text, usespeech generation endpoint:

- `POST /v1/audio/tasks`
- `GET /v1/audio/tasks/{task_id}`

If you want to create your own `voice_id`, then use that `voice_id` in speech generation, use this page voice endpoints.

## 1. supportsCapability
