What Is Text To Speech Converter In The First Place? (Core Basics)

Text To Speech (TTS) is a technology that empowers your text to be converted into speech verbal sounds.

In this project (Text To Speech Converter), you can convert your text into speech with different voices and accents powered by native output methods for every type of device.

A pause and resume button that is embedded into the core of your text is above the minimum requirement of ~125 words/characters.

About The Text To Speech Converter Project (Understanding Basics)

In the JavaScript code, originally, I got the user text and call a function textToSpeech() with parsing the user input text as an argument.

Inside this function, leveraging the speech synthesis property of the window object, I converted the user input text to speech.

Speech Synthesis is defined as a web speech API that moderates the speech service using native speech verbal’s available on the base device.
After this, I got all the available verbal voices from the user device using the getVoices() scheme of Speech Synthesis and insert it into the attributed HTML select tag.

That’s all and I request you to continue reading to get more knowledge depth on what the code is actually performing.

Finally, create a JavaScript file with a filename of script.js and paste the following code in your JavaScript file. Save It, you have to create a file with .js extension at last.

const textarea = document.querySelector("textarea"),
voiceList = document.querySelector("select"), // Selection
speechBtn = document.querySelector("button");

let synth = speechSynthesis,
isSpeaking = true;

voices();

function voices(){
    for(let voice of synth.getVoices()){
        let selected = voice.name === "Google US English" ? "selected" : "";
        let option = `<option value="${voice.name}" ${selected}>${voice.name} (${voice.lang})</option>`;
        voiceList.insertAdjacentHTML("beforeend", option); // Getting Verbal's 
    }
}

synth.addEventListener("voiceschanged", voices);

function textToSpeech(text){
    let utterance = new SpeechSynthesisUtterance(text);
    for(let voice of synth.getVoices()){
        if(voice.name === voiceList.value){
            utterance.voice = voice;
        }
    }
    synth.speak(utterance);
}

speechBtn.addEventListener("click", e =>{
    e.preventDefault();
    if(textarea.value !== ""){
        if(!synth.speaking){
            textToSpeech(textarea.value);
        }
        if(textarea.value.length > 80){
            setInterval(()=>{
                if(!synth.speaking && !isSpeaking){
                    isSpeaking = true;
                    speechBtn.innerText = "Convert To Speech"; //Execute
                }else{
                }
            }, 500);
            if(isSpeaking){
                synth.resume();
                isSpeaking = false;
                speechBtn.innerText = "Pause Speech"; //Pause
