developers of Voice Candy pitch is as doing for microphones what
Photobooth does for webcams. It is a clever little app that can change the sound of your voice using a variety of
effects (including the popular Vader. I imagine lot of people saying, 'iMac, I am your father.'). But it doesn't stop
there! You can also set up voice reminders.
All of this for $12.95 (there is a 15 day demo).
