The cat wants you to talk really loud so that the loudness is above 50 for about two seconds! If you don't have a microphone, then the cat can't hear you
Instead of voice recognition which is impossible, I used the loudness instead, which I think is a good idea. This is simple to make, I hardly used anything and anytime at all! Feel free to look inside, if you do and you're wondering what I used, I promise, the next word you'll be saying is 'oh' or something like that ;D
