"Sonic Vox, for iPhone, by SMule.

"Instant change. Instant fun.
Tired of your same old voice? Seeking a little vocal variety? Get into character with Smule's Sonic Vox, the real-time voice shifter.
With Sonic Vox you can alter your voice with a swipe of your finger. Want to cross over to the Dark Side? Slide your finger to the left. Now say it. You know you want to. "Luke, I am your…"
Or maybe you are feeling conflicted about having lost a "preciousssss" ring? Move your finger back and forth horizontally and go ahead, rant on.
Transform your voice even more. Simply swipe your finger up and down and hear what happens… happens… happens…
Sonic Vox is easy to use. You can test it out by talking in your phone. It's even better with headphones. It is most effective, however, if you plug your iPhone into speakers and use your phone like a real microphone.
Adventurous? Connect your iPhone (speaker-out) to your MacBook (mic-in). Switch the system preference to Line-In. Launch Sonic Vox. Launch Skype. Make that call.
We hope you enjoy Sonic Vox. Try other entertaining apps from Smule, including the acclaimed Sonic Lighter and Sonic Boom.
Sonic Vox requires an iPhone or iPod Touch 2nd Generation with Mic."
