How to Implement Text-to-Speech in JavaScript

To implement text-to-speech in JavaScript, you can use the speechSynthesis API provided by the Web Speech API. This API allows you to convert text to speech and play the resulting audio using a speech synthesis engine installed on the user’s device.

Here is an example of using the speechSynthesis API to convert text to speech and play the resulting audio in JavaScript:

// Create a new SpeechSynthesisUtterance instance
const utterance = new SpeechSynthesisUtterance();

// Set the text
utterance.text = "Hello, world!";

// Set the voice to be used for the utterance
utterance.voice = speechSynthesis.getVoices()[0];

// Set the language of the utterance
utterance.lang = 'en-US';

// Play the utterance using the speech synthesis engine
speechSynthesis.speak(utterance);

The speechSynthesis API provided by the Web Speech API allows you to convert text to speech and play the resulting audio using a speech synthesis engine installed on the user’s device.

The speechSynthesis API works by creating a SpeechSynthesisUtterance instance, which represents a piece of text to be spoken. The text to be spoken is set using the text property of the utterance variable, and the voice to be used for the utterance is set using the voice property. The language of the utterance can also be set using the lang property.

Once the utterance has been configured, it can be played using the speak method of the speechSynthesis object. This will cause the speech synthesis engine installed on the user’s device to convert the text to speech and play the resulting audio.

Overall, the speechSynthesis API provided by the Web Speech API allows you to convert text to speech and play the resulting audio using a speech synthesis engine installed on the user’s device. It works by creating a SpeechSynthesisUtterance instance, setting the text, voice, and language properties of the utterance, and then playing the utterance using the speak method of the speechSynthesis object.
