Text-to-Speech Converter Project: A Practical Tutorial with JavaScript

https://fsiblog.io/
, we will walk you through creating a simple and functional Text-to-Speech (TTS) converter using HTML, CSS, and JavaScript. By the end of this project, you'll have a working TTS application that can read aloud text input by the user. This project is perfect for beginners looking to explore JavaScript's capabilities and practical use cases.

What is Text-to-Speech (TTS)?

Text-to-Speech (TTS) is a technology that converts written text into spoken words. It is commonly used in accessibility tools, educational software, and virtual assistants. In web development, JavaScript provides powerful tools like the Web Speech API to implement TTS functionality.

Tools and Technologies Required

HTML: For creating the structure of the application.

CSS: For styling the interface.

JavaScript: To implement the TTS functionality using the Web Speech API.

Step 1: Setting Up the Project

Create a new folder for your project and add three files:

index.html

style.css

script.js

1. HTML Structure

The index.html file will define the structure of the application.

Text-to-Speech Converter

<textarea id="text" placeholder="Enter text here..."></textarea> <button id="speak">Speak</button>

2. CSS Styling

The style.css file will style the application to make it visually appealing.

body {
font-family: Arial, sans-serif;
background-color: #f4f4f9;
margin: 0;
display: flex;
justify-content: center;
align-items: center;
height: 100vh;
}

.container {
text-align: center;
background: white;
padding: 20px;
border-radius: 10px;
box-shadow: 0 4px 10px rgba(0, 0, 0, 0.1);
max-width: 400px;
width: 100%;
}

h1 {
color: #333;
margin-bottom: 20px;
}

textarea {
width: 100%;
height: 100px;
padding: 10px;
font-size: 16px;
border: 1px solid #ccc;
border-radius: 5px;
margin-bottom: 10px;
}

button {
background-color: #007bff;
color: white;
border: none;
padding: 10px 20px;
font-size: 16px;
border-radius: 5px;
cursor: pointer;
transition: background-color 0.3s;
}

button:hover {
background-color: #0056b3;
}

3. JavaScript Functionality

The script.js file will handle the TTS functionality using the Web Speech API.

// Select DOM elements
const textArea = document.getElementById('text');
const speakButton = document.getElementById('speak');

// Function to speak the text
function speakText() {
const text = textArea.value;
if (!text.trim()) {
alert('Please enter some text to speak!');
return;
}

const utterance = new SpeechSynthesisUtterance(text);
window.speechSynthesis.speak(utterance);
}

// Add event listener to the button
speakButton.addEventListener('click', speakText);

Step 2: Testing Your Application

Open the index.html file in your browser.

Enter some text in the textarea.

Click the Speak button to hear the text read aloud.

How It Works

The Web Speech API provides the SpeechSynthesis interface to convert text into speech.

The SpeechSynthesisUtterance object represents the text to be spoken.

The speak method of SpeechSynthesis reads the text aloud.

Enhancements and Customization

To make the project more advanced, you can:

Add Voice Options: Allow users to choose different voices.

Adjust Speed and Pitch: Add controls for speech rate and pitch.

Save Input: Enable saving and loading of frequently used text.

Mobile-Friendly Design: Ensure the layout is responsive for mobile devices.

Conclusion

Congratulations! You have successfully built a Text-to-Speech converter using HTML, CSS, and JavaScript. This project demonstrates the power of the Web Speech API and provides a foundation for creating more advanced accessibility tools. Experiment with additional features and enhance the functionality to make it even more engaging!

Happy coding!
