I want to do some YouTube videos but stay anonymous. So I'm planning on showing my body (fully dressed for the record) but not my face and I also would like to disguise my voice. Is there a way to alter your voice slightly, either software or hardware, that's not too freaky? I don't want to sound robotic or like something out of an 80's horror flick. I just want a slight alteration to my voice so the boys in the office won't say, "I recognize that bastard!"
