How can PHP and JavaScript work together to enhance speech output features on a website?

To enhance speech output features on a website, PHP can be used to generate dynamic content and JavaScript can be used to interact with the browser's speech synthesis API to read out the content. By combining these two technologies, users can have a more interactive and accessible experience on the website.

<?php
echo '<button onclick="speak()">Click me to hear speech output!</button>';
echo '<p id="textToSpeak">This is the text that will be read out loud.</p>';
?>
