MorphVOX Pro is a program that can change your voice when you´re talking through your PC´s microphone when you´re using your favorite Instant Messenger, or when you´re playing with an online game. MorphVOXTM Pro will change your voice, making you sound like different persons or even animals, just for fun. You can also record your distorted voice in a sound file, to use it later as a sound effect or even a ringtone.

The program comes, by default, with six voice packs. Using them, you can make your voice sound like that of a child, a dog, a demon, a woman, a robot or a man. The program modifies the pitch and timbre of your voice through predefined parameters, which you can change at will, creating new voice effects.
