Not a bad little animation, but the sound a weak point. There are a couple of ways that you can prevent that audio spiking that occurs when you spit your "p" sounds into the mic:
1) hold a piece of thin cloth or even a post-it note up between your mouth and the microphone when you've got trouble consonants like "p". If you do it correctly, you can prevent the rush of air that crashes the mic without losing the annunciation.
2) turn down the audio-input a little, and then fiddle with the output level to get it as loud as you can before going in to the red. This will prevent input spiking so that you don't get that crackling distortion.
I thought it was cute.
