Voxal Voice Changer is a very interesting and powerful human voice changing program for Windows and Mac platforms, developed by NCH Software from Australia. It allows users to change their voice in real time, and provides a variety of sound effects, such as: robot, girl, boy, alien, atmosphere, echo, etc.

In addition to face, we are also able to identify an acquaintance or stranger by his/her voice. Put in a different way, in environment not talking with each other face to face, we can cheat or joke with our friends through voice imitation.
