MiniMax speech production

Use MiniMax when the production goal is generated speech: narration, localized VO, ad reads, audiobook-style segments, synthetic dialogue, product walkthroughs, voice-agent responses, or approved voice cloning. Do not use this skill for MiniMax video, music generation, image generation, or general LLM calls except where they affect speech production.

The facts below were verified against official MiniMax API documentation, release notes, pricing, and policy pages on 2026-07-10. Treat model IDs, prices, rate limits, retention windows, voice lists, and policy language as volatile; re-check before a paid or regulated production run.

Capability boundary

Documented MiniMax speech capabilities:

• Synchronous text-to-audio over HTTP: POST https://api.minimax.io/v1/t2a_v2.
• Synchronous text-to-audio over WebSocket: wss://api.minimax.io/ws/v1/t2a_v2.
• Asynchronous long-form text-to-audio: create a task with POST /v1/t2a_async_v2, query it, then retrieve the generated file.
• System voices, cloned voices, and text-designed voices, queryable through Voice Management.
• Rapid voice cloning through file upload plus POST /v1/voice_clone.
• Voice design through POST /v1/voice_design, where a text description produces a generated voice_id and preview audio.
• Subtitle timestamp generation from TTS (sentence, word, or word_streaming depending on streaming mode).
• An ASR-based validation check inside voice cloning when text_validation is provided.
