MiniMax Voice Design

MiniMax Voice Design is a state-of-the-art voice synthesis model developed by MiniMax. Instead of cloning a voice from a reference audio, it generates high-quality voices based on your textual voice description, allowing you to create speech with the desired tone, accent, and personality.

Key Features

High-Fidelity Voice Generation Produces speech that matches your description with natural prosody and pronunciation.
Flexible Voice Design Create a wide range of voices by simply describing the desired characteristics—no reference audio required.
Emotion and Tone Control Fine-tune speaking style and emotion for storytelling, games, and character dialogue.
Multilingual Output Supports voice design across different languages and smooth code-switching.
Low-Latency Inference Optimized for real-time use cases, including live interactions and dialogue generation.

Use Cases

AI voiceovers for content creators and influencers
Personalized digital assistants and chatbots
Audiobook narration in a specific style
Interactive gaming and character voices
Assistive speech for individuals with voice loss

Model Overview

MiniMax Voice Design uses a neural TTS pipeline with robust speaker and prosody modeling. By leveraging your textual description, it offers clarity, control, and speed, delivering production-ready results in diverse environments.

Note

Your custom voice ID must be used at least once with one of the voice models on our platform to be saved permanently. Such as:

Otherwise, we can only store it for 7 days. After that, it will be deleted and the voice ID will no longer be callable.

For easier reuse later, please make sure to use your voice ID once in one of the models above after creating it.

Voice Design API — Quick start

Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/minimax/voice-design with your input as JSON. The endpoint returns a prediction id; poll the prediction endpoint until status flips to completed, then read the output URL from data.outputs[0]. Examples for Voice Design below.

HTTP example

# Submit the prediction
curl -X POST "https://api.wavespeed.ai/api/v3/minimax/voice-design" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $WAVESPEED_API_KEY" \
  -d '{
    "prompt": "A cinematic shot of a city at sunset, soft golden light",
    "text": "Hello! Welcome to Wavespeed! This is a preview of your cloned voice. I hope you enjoy it"
}'

# Response includes a prediction id. Poll for the result:
curl -X GET "https://api.wavespeed.ai/api/v3/predictions/{request_id}/result" \
  -H "Authorization: Bearer $WAVESPEED_API_KEY"

# When status is "completed", read the output from data.outputs[0].

Node.js example

// npm install wavespeed
const WaveSpeed = require('wavespeed');

const client = new WaveSpeed(); // reads WAVESPEED_API_KEY from env

const result = await client.run("minimax/voice-design", {
        "prompt": "A cinematic shot of a city at sunset, soft golden light",
        "text": "Hello! Welcome to Wavespeed! This is a preview of your cloned voice. I hope you enjoy it"
});

console.log(result.outputs[0]); // → URL of the generated output

Python example

# pip install wavespeed
import wavespeed

output = wavespeed.run(
    "minimax/voice-design",
    {
    "prompt": "A cinematic shot of a city at sunset, soft golden light",
    "text": "Hello! Welcome to Wavespeed! This is a preview of your cloned voice. I hope you enjoy it"
}
)

print(output["outputs"][0])  # → URL of the generated output

Voice Design API — Frequently asked questions

What is the Voice Design API?

Voice Design is a MiniMax model for audio generation, exposed as a REST API on WaveSpeedAI. MiniMax Voice Design generates natural voices from textual descriptions - no cloning - lets you set tone, accent and personality. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing. You can call it programmatically or try it from the playground above.

How do I call the Voice Design API?

POST your input parameters to the model's REST endpoint (shown in the API tab of this playground) with your WaveSpeedAI API key in the Authorization header. Submission returns a prediction ID; poll the prediction endpoint until status flips to "completed", then read the output URL from the result. The playground generates a ready-to-paste code sample in Python, JavaScript, or cURL for whatever inputs you've set. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/minimax/minimax-voice-design.

How much does Voice Design cost per run?

Voice Design starts at $0.50 per run. That figure is the base price — the final charge scales with the parameters you set in the form (output size, length, count, references, or whatever knobs this model exposes), so a higher-quality or larger output costs more than a minimal one. The exact cost for your current input is shown live next to the Generate button before you submit, and the actual per-call charge is recorded on the prediction afterwards.

What inputs does Voice Design accept?

Key inputs: `prompt`, `custom_voice_id`, `text`. The full JSON schema (types, defaults, allowed values) is rendered above the Generate button and mirrored in the API reference at https://wavespeed.ai/docs/docs-api/minimax/minimax-voice-design.

How long does Voice Design take to generate?

Average end-to-end generation time on WaveSpeedAI is around 22 seconds per request — measured across recent runs. Queue time scales with global demand; live status is visible in the prediction record.

Can I use Voice Design outputs commercially?

Commercial usage rights depend on the model's license, set by its provider (MiniMax). The license summary appears on the model card above; see WaveSpeedAI's Terms of Service for platform-level conditions.
