The Yuui project

Yuui explored voice cloning and real-time voice transformation. The descriptions below are kept for reference. These services are no longer available.

Most Accurate Cloning

Voice cloning from short recordings, designed to preserve timbre, prosody, and speaking style.

AI Voice Marketplace

A planned marketplace for discovering and sharing AI voices created by the community.

Developer SDK

TypeScript-friendly SDKs, REST endpoints, and real-time WebSocket streaming for voice transformation.

How the platform was designed

The planned workflow for voice cloning and real-time transformation.

01

Upload Audio

Record or upload clean voice samples. Our pipeline trains a reusable cloned voice profile that can be used for live or offline synthesis.

02

Clone & Route

Select your cloned voice and route audio through the real-time changer. Tune parameters such as pitch, speaking rate, and expressiveness.

03

Deploy Anywhere

Connect with secure API keys using SDK or direct WebSocket sessions. Stream transformed audio live or generate files asynchronously.

This SDK example is archived. API access is no longer available.

index.ts
import { Studio } from "@yuui/sdk";

const studio = new Studio({
  apiKey: process.env.YUUI_API_KEY,
});

// Clone a voice from audio
const voice = await studio.voices.clone({
  name: "My Voice",
  files: ["sample.mp3"],
});

// Open a low-latency streaming session
const session = await studio.stream.connect({
  voiceId: voice.id,
  transport: "websocket",
});

// Transform audio in real-time
await session.sendAudio(chunk);
session.on("audio", (packet) => {
  play(packet.output);
});
