MiniMax Voice Design

Overview

minimax-voice-design is a text-to-voice synthesis service. Describe a voice in plain English (“warm female narrator with British accent, mid-30s”) and MiniMax synthesizes a complete voice profile. The returned voice_id works the same way voice clone’s output does — usable across all MiniMax HD/Turbo TTS calls. Right for branding when no voice talent is available, fictional characters, persona voices for chatbots and agents, and any case where a written brief is all you have.

	Cost
Per designed voice	$4.20 flat (one-time)

Voice design is ~2× the cost of voice clone because synthesizing timbre from a text description is strictly more compute-intensive than reproducing a captured one.

Use this when

You don’t have voice talent and want a polished voice anyway.
You’re prototyping characters and want to iterate on voice descriptions cheaply.
You need a chatbot or agent with a distinctive but synthesized persona.

Pick something else when

You have reference audio → minimax-voice-clone ($2.10/voice).
Stock voices are sufficient → use GET /v1/audio/voices directly.
