The first way is by checking our operating system and version on. We can perform this check in one of two ways. Since this API isn’t compatible with all browsers, we'll need to check for compatibility. To create our JavaScript Text-to-Speech application, we are going to utilize JavaScript's built-in Web Speech API. If everything went ok, you should be left with something like this: Our App Step 2 - Checking Browser Compatibility Make sure to save the file and refresh your browser, you should now see a little window popping up with the text "It works!". To add an alert to our code, we add the line of code below to our script.js file. Since we imported the script.js file to our index.html file above, we can test its functionality by simply sending an alert. Now that we have finished the index.html file, we can move on to creating the script.js JavaScript file. This tells our application the name of the JavaScript file that stores the functionality for the application. At the bottom of the element, we import our script.js file. This tells our application to style itself according to the contents of style.css. ![]() Inside of the element, which contains metadata for our HTML file, we import style.css. Remember, the input and the button have no functionality yet - we'll add that in later using JavaScript. We finally wrap all of these objects inside of a. We add an element which acts as a title for the application, an field in which we will enter the text we want spoken, and a which we will use to submit this input text. The HTML file index.html defines our application's structure which we will add functionality to with the JavaScript file. ![]() We'll also use a CSS file called style.css to add some margins and to center things, but it’s entirely up to you if you want to include this styling file. Step 1 - Setting Up The Appįirst, we set up a very basic application using a simple HTML file called index.html and a JavaScript file called script.js. You can also view a live version of the app here. In this tutorial, we will learn how to build a very simple JavaScript Text-to-Speech application using JavaScript's built-in Web Speech API.įor your convenience, we have provided the code for this tutorial application ready for you to fork and play around with over at Replit, or ready for you to clone from Github. When building an app, you may want to implement a Text-to-Speech feature for accessibility, convenience, or some other reason.
