Well, clearly until I found the resistor that controlled the speed and pitch of each sound, cut it, and replaced it with a dial.
So, now, it says in a deep barcitone, stretched over about three seconds, DUOUBLEYEEEWWWW.
This works for all letters, except the letter "R". For some reason, while I can get all the letters to chirp quick-like by turning the dial to the right, "R" is the oddball, and it won't play unless there's a fairly high amount of resistance. So it'll go low and slow, but not quick and high.
Only R. Weird.
