Text To Speech Converter in HTML CSS & JavaScript

Hey friends, today in this blog, you’ll learn how to create a Text To Speech Converter in HTML CSS & JavaScript. In the earlier blog, I have shared how to Build A Dictionary App in JavaScript, and now it’s time to create a Text To Speech Converter Web Application.

Text To Speech (TTS) is a technology that enables your text to be converted into speech sounds. In this project (Text To Speech Converter App), you can convert your text into speech on different voices. A pause and resume option is also available if your text character length is more than 80.


You can watch a demo or full video tutorial of this JavaScript project (Text To Speech Converter App – TTS).

Video Tutorial of Text To Speech Converter in JavaScript

 
In the video, you have seen a demo of the Text To Speech Converter App and knew how I made it using HTML CSS & Vanilla JavaScript. No external JavaScript libraries or APIs are used to make this TTS App and I hope you have liked this project.

If you liked it and want to get source codes of this Text To Speech Converter App then you can copy or download coding files from the bottom of this page. But before you go to download the codes, let’s understand the main JS codes and concepts behind creating this project.


In the JavaScript code, first, I got the user text and call a function textToSpeech() with passing user text as an argument. Inside this function, using the speech synthesis property of the window object, I converted the entered text to speech. Speech Synthesis is a web speech API that controls the speech service.

After this, I got all available voices from the user device using the getVoices() method of Speech Synthesis and insert it into HTML select tag. That’s all and I request you to watch the full video where I have explained each JavaScript line with a written comment so you can understand the codes more easily.

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);
    }
}

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;
