This gizmo reminds me of a cassette recorder, CD player or "old fashioned" record player/victrola. I added three momentary
pushbuttons. If you push the first button while a tune is playing or the default (programmed, if you
will) voice is speaking, the sound speeds up. The result? Noises resembling mice squeaking or some other rodents
"speaking" in their own respective fashions. The second button produces a buzzing sound and the third alters the voice
in such a way as to lower its pitch. Thus the default woman's voice begins to resemble that of a man.
