## 📖 Introduction



[🤖 Lobe Chat](https://github.com/lobehub/lobe-chat) supports Text-to-Speech (TTS) and Speech-to-Text (STT) technologies, enabling our application to convert text messages into clear voice outputs,

allowing users to interact with our conversational agent as if they were talking to a real person. Users can choose from a variety of voices to pair with the agent.



In the process of implementing this feature, we found that there was no satisfactory TTS (Text-to-Speech) frontend library available on the market.

As a result, we invested a lot of effort, including data conversion, audio progress management, and speech visualization, among other tasks.



> \[!NOTE]

>

> Therefore, we decided to refine our implementation and make it open source, hoping to assist developers who wish to implement TTS.

> [@lobehub/tts][npm-release-link] is a high-quality TTS toolkit developed in TypeScript, which supports usage both on the server-side and in the browser.

>

> - **Server-side:** With just 15 lines of code, you can achieve high-quality voice generation capabilities comparable to OpenAI's TTS service. It currently supports EdgeSpeechTTS, MicrosoftTTS, OpenAITTS, and OpenAISTT.

> - **Browser-side:** It provides high-quality React Hooks and visual audio components, supporting common functions such as loading, playing, pausing, and dragging the timeline. Additionally, it offers a very rich set of capabilities for adjusting the audio track styles.



## 📦 Usage



### Generate Speech on server



run the script below use Bun: `bun index.js`



```js

// index.js

import { EdgeSpeechTTS } from '@lobehub/tts';

import { Buffer } from 'buffer';

import fs from 'fs';

import path from 'path';



// Instantiate EdgeSpeechTTS

const tts = new EdgeSpeechTTS({ locale: 'en-US' });



// Create speech synthesis request payload

const payload = {

  input: 'This is a speech demonstration',

  options: {

    voice: 'en-US-GuyNeural',

  },

};



// Call create method to synthesize speech

const response = await tts.create(payload);



// generate speech file

const mp3Buffer = Buffer.from(await response.arrayBuffer());

const speechFile = path.resolve('./speech.mp3');



fs.writeFileSync(speechFile, mp3Buffer);

```



> \[!IMPORTANT]\

> **Run on Node.js**

>

> As the Node.js environment lacks the `WebSocket` instance, we need to polyfill WebSocket. This can be done by importing the ws package.



```js

// import at the top of the file

import WebSocket from 'ws';



global.WebSocket = WebSocket;

```



### Use the React Component



```tsx

import { AudioPlayer, AudioVisualizer, useAudioPlayer } from '@lobehub/tts/react';



export default () => {

  const { ref, isLoading, ...audio } = useAudioPlayer(url);



  return (

    

      

      

    

  );

};

```
