# @intentface/react-speech-recognition

`@intentface/react-speech-recognition` is a custom React hook that provides an easy-to-use interface for integrating speech recognition capabilities into your React applications. It leverages the native browser `SpeechRecognition` API, allowing you to capture and process voice inputs with customizable options.

## Installation

You can install this package via npm:

```bash
npm install @intentface/react-speech-recognition
```

## Usage

Here’s a basic example of how to use the `useSpeechRecognition` hook in your React project:

```tsx
import React from "react";
import { useSpeechRecognition } from "@intentface/react-speech-recognition";

const SpeechComponent = () => {
const {
transcript,
interimTranscript,
isListening,
isFinal,
isSupported,
start,
stop,
error,
} = useSpeechRecognition({
lang: "en-US", // Language for speech recognition (default is "en-US")
continuous: false, // Whether to keep listening or stop after receiving input
timeout: 5000, // Automatically stop listening after 5 seconds
onUpdate: ({ transcript, interimTranscript, isFinal }) => {
console.log("Update:", { transcript, interimTranscript, isFinal });
},
onError: ({ error }) => {
console.error("Speech recognition error:", error);
},
});

if (!isSupported) {
return <p>Your browser does not support Speech Recognition.</p>;
}

return (
<div>
<h1>Speech Recognition Example</h1>
<p>Transcript: {transcript}</p>
<p>Interim Transcript: {interimTranscript}</p>
<p>
Status:{" "}
{isListening ? "Listening..." : isFinal ? "Finalized" : "Stopped"}
</p>
{error && <p>Error: {error.message}</p>}
<button onClick={start}>Start Listening</button>
<button onClick={stop}>Stop Listening</button>
</div>
);
};

export default SpeechComponent;
```

### API

The `useSpeechRecognition` hook returns an object containing the following properties:

#### Returned Values

- `transcript`: The final processed transcript of the recognized speech.
- `interimTranscript`: The current intermediate transcript while speech is being processed.
- `isListening`: A boolean indicating whether the recognition is currently active.
- `isFinal`: A boolean indicating whether the current session has ended and the transcript is finalized.
- `isSupported`: A boolean indicating whether the browser supports speech recognition.
- `start()`: A function to start speech recognition.
- `stop()`: A function to stop speech recognition.
- `error`: An object containing any speech recognition errors that occurred.

#### Options

The hook accepts an options object with the following fields:

- `lang`: The language for speech recognition (default is `"en-US"`).
- `continuous`: If `true`, the recognition will continue until stopped manually (default: `false`).
- `timeout`: Time in milliseconds to automatically stop recognition after no speech is detected (default: `undefined`). If left _undefined_, browsers default behaviour is respected.
- `onUpdate`: A callback function triggered when there is an update in the transcript. Receives an object with `{ transcript, interimTranscript, isFinal }`.
- `onError`: A callback function triggered when an error occurs. Receives an object with `{ error }`.

### Features

- **Customizable Language**: Set the language of recognition with the `lang` option.
- **Continuous Listening**: Option to listen continuously for speech input.
- **Timeout Control**: Automatically stop recognition after a set period of inactivity.
- **Error Handling**: Receive error information via the `onError` callback.
- **Interim and Final Transcripts**: Access both the interim (in-progress) and final transcripts.

### Browser Compatibility

This hook uses the native `SpeechRecognition` API (also known as `webkitSpeechRecognition` in some browsers). Below is a list of supported browsers:

| Browser | Supported Versions |
| ------- | ------------------ |
| Chrome | Version 33+ |
| Safari | Version 14+ |
| Edge | Version 79+ |

> Note: The `SpeechRecognition` API is not supported in Firefox or Internet Explorer. Please check for browser compatibility using the `isSupported` flag provided by the hook.
