Hello World

It's as easy as adding one javascript file to your document and defining the commands you want.

<script src="//"></script>
if (annyang) {
  // Let's define a command.
  const commands = {
    'hello': () => { alert('Hello world!'); }

  // Add our commands to annyang

  // Start listening.

Adding a GUI

You can easily add a GUI for the user to interact with Speech Recognition using Speech KITT.

Speech KITT makes it easy to add a graphical interface for the user to start or stop Speech Recognition and see its current status. KITT also provides clear visual hints to the user on how to interact with your site using their voice, providing instructions and sample commands.

Speech KITT is fully customizable and comes with many different themes, and instructions on how to create your own designs.
