text to speech in javascript

To enable text-to-speech in JavaScript, you can make use of the Web Speech API. Here's an example code snippet:

index.tsx
// create a new instance of the SpeechSynthesisUtterance object
const msg = new SpeechSynthesisUtterance();

// set the text that you want to convert to speech
msg.text = "Hello, World!";

// use the speech synthesis API to speak the text
window.speechSynthesis.speak(msg);

In this example, we're creating a new instance of the SpeechSynthesisUtterance object, setting the text to be spoken to "Hello, World!" and then using the window.speechSynthesis.speak function to actually speak the text.

You can customize the speech by setting various properties on the msg object, such as the voice, pitch, and rate of speech. For example, to change the voice to a British accent, you could use the following code:

index.tsx
msg.voiceURI = 'Google UK English Female';
msg.lang = 'en-GB';

Overall, the Web Speech API provides a simple way to add text-to-speech functionality to your JavaScript applications.
