Passing PHP variable to Javascript not working

I'm trying to pass a php variable to javascript, but it doesn't seem to be working. I know that it works with just the javascript, just that it doesn't work when I'm trying to pass it with PHP. What am I doing wrong?

<?php

$sayIt = "Hello";

echo "
<script type = 'text/javascript'>

var msg = new SpeechSynthesisUtterance($sayIt);
window.speechSynthesis.speak(msg);

</script>
";

?>

It doesn't work because the PHP will interpret the code like this:

<script type = 'text/javascript'>

var msg = new SpeechSynthesisUtterance(Hello);
window.speechSynthesis.speak(msg);

</script>

Then JavaScript will consider the Hello as a variable, which may not defined in JavaScript, you may should write it like this:

echo "<script type = 'text/javascript'>

var msg = new SpeechSynthesisUtterance(\"$sayIt\");

window.speechSynthesis.speak(msg);

";

Then it will be interpreted to this:

<script type = 'text/javascript'>

var msg = new SpeechSynthesisUtterance("Hello");
window.speechSynthesis.speak(msg);

</script>

Hope it will help you!
