Introduction

Voice-controlled applications are becoming increasingly popular, and integrating speech recognition can add a new dimension to user interactions. In this tutorial, we’ll explore how to use the react-speech-recognition module to seamlessly integrate speech recognition into a Next.js application. This module provides a simple yet powerful way to capture and process speech input in React-based projects.

Prerequisites

Before diving into the implementation, make sure you have Node.js and npm installed on your machine.

# Install Node.js and npm

Setting Up a Next.js Project

If you haven’t created a Next.js project yet, you can do so using the following commands:

# Create a new Next.js project
npx create-next-app my-speech-recognition-app
cd my-speech-recognition-app

Installing react-speech-recognition

Now, install the react-speech-recognition module using npm:

# Install react-speech-recognition
npm install react-speech-recognition

Implementing Speech Recognition in Next.js

Create a new component that will handle the speech recognition functionality. Let’s name it SpeechRecognition.js:

// components/SpeechRecognition.js
import React from 'react';
import SpeechRecognition, { useSpeechRecognition } from 'react-speech-recognition';

const SpeechRecognitionComponent = () => {
  const { transcript, listening, resetTranscript } = useSpeechRecognition();

  const startListeningHandler = () => {
    SpeechRecognition.startListening();
  };

  const stopListeningHandler = () => {
    SpeechRecognition.stopListening();
  };

  return (
    

      
Speech Recognition
      
{transcript}
      
        Start Listening
      
      
        Stop Listening
      
      Reset Transcript
    
  );
};

export default SpeechRecognitionComponent;

Now, use this component in your main page:

// pages/index.js
import Head from 'next/head';
import SpeechRecognitionComponent from '../components/SpeechRecognition';

const Home = () => {
  return (
    

      
        
        
      

      

        
Next.js Speech Recognition
        
      
    
  );
};

export default Home;

Testing the Application

Run your Next.js application and open it in your browser:

npm run dev

Visit http://localhost:3000 in your browser. You should see the main page with the Speech Recognition component. Click “Start Listening” to enable speech recognition and test it by speaking into your microphone.

You’ve successfully integrated speech recognition into a Next.js application using the react-speech-recognition module. This opens up new possibilities for creating interactive and accessible user interfaces that respond to voice commands.
