I actually do have one of those little toy voice changers. 2 problems with them: One, the quality of the output is poor, and then being transmited over the phone makes it almost unintelligable. The 2nd problem with it is that when I talk loud enough for it’s mic to work properly, the phone can also pick up my voice.
So, i figured if I could use the modem in my laptop, not only would an audio app sound better, but it would also hide my real voice. It’s hard to prank your friend when they can still hear you over the changer.
