A fun and simple toy that modifies your voice in 3 different ways, producing surprising vocal effects excellent for pranks or messing with your friends. Modes include Robot, which removes vocal inflection and adds a mechanical quality to your voice; Boy, which deepens and compresses your voice to make you sound like a young boy, and Kid, which knocks the pitch of your voice into a higher register. Just hold down the trigger and speak into the end of the changer to hear your voice like you’ve never heard it before! Makes a great stocking stuffer or party favor.
