Using a TTS API with JavaScript enhances web application user experiences. The Web Speech API, supported by Chrome and Firefox, offers speech synthesis and recognition capabilities. This tutorial covers integrating a TTS API, converting text to speech, customizing settings, and utilizing available voices.

Using a text-to-speech (TTS) API with JavaScript can greatly enhance the user experience of web applications. The Web Speech API, supported by modern browsers like Chrome and Firefox, provides a powerful set of tools for speech synthesis and speech recognition. In this tutorial, we will explore how to integrate a TTS API into your JavaScript code, convert text to speech, customize speech settings, and utilize available voices.

Getting started with JavaScript and Text to Speech

To get started, you'll need a basic understanding of HTML, CSS, and JavaScript. Begin by creating an HTML file and linking your JavaScript file using the script src tag. In your JavaScript file, initialize the speech synthesis object and set up an event listener for when the voices are ready. const synth = window.speechSynthesis; // Wait for voices to be loaded synth.onvoiceschanged = () => { const voices = synth.getVoices(); // Do something with the available voices }; Once the voices are loaded, you can access them using the synth.getVoices() method. This will return a list of available voices that you can use for speech synthesis. You can loop through the voices using forEach and display them in your HTML. const voiceSelect = document.getElementById('voice-select'); voices.forEach((voice) => { const option = document.createElement('option'); option.textContent = ${voice.name} (${voice.lang}); option.setAttribute('value', voice.lang); voiceSelect.appendChild(option); }); Next, you can create a function to synthesize speech from the selected voice. This function takes the text input from a textarea element and uses the selected voice to generate speech. const speak = () => { const text = document.getElementById('text-input').value; const voice = voices[voiceSelect.selectedIndex]; const utterance = new SpeechSynthesisUtterance(text); utterance.voice = voice; synth.speak(utterance); }; Add an event listener to the button or form submit to trigger the speak function. const button = document.getElementById('speak-button'); button.addEventListener('click', speak); With these few lines of code, you can convert text to speech in real-time. Customize the speech rate, pitch, and volume by setting properties on the SpeechSynthesisUtterance object. utterance.rate = 0.8; utterance.pitch = 1; utterance.volume = 1; As you continue to explore the Web Speech API, you'll find additional features for speech recognition and controlling speech synthesis events. Remember to consult the official documentation for more details and attributions.
