Ultra Voice Changer
This application will help you change your voice beyond recognition.
First you must record the desired voice message, and then you can apply several types of effects. The program includes more than 10 kinds of different filters, among them the voice of an alien, cyborg, robot, and others. Once you get the desired modified record of your voice, you can save it, listen to, set as a ringtone or send it by e-mail.
