@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:

npm install @intentface/react-speech-recognition

Usage

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

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.

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+
