Zebble makes it easy to listen to the user's voice to recognize the spoken words and use them for any kind of processing in your app.
void Listener(string heardWords)
// TODO: Use the words as you please.
// The provided string may contain a single word; or a number of them.
// For example, you can use a class-level StringBuilder class, add all heard words to it, and show the concatenated result on the screen.
Note: It's a good practice to Stop the listener in your module's Dispose() method.
