If a natural Santa voice is impossible, it's possible to purchase "AV Voice Changer Software Diamond" from Nickvoice.com. Software users change the timbre, pitch and sound quality of their voices to create a Santa-like character. Outfit7 offers an app called “Talking Santa,” with which players speak into the microphone of a device and Santa repeats in his voice. “Talking Santa” enables players to send personalized Christmas cards and have Santa deliver each holiday message.
