This DIY Digital Voice Changer Kit lets you mask the sound of your voice by playing with the pitch and vibrato of your speech. Just speak into the built-in microphone, adjust the pitch control, and you can sound like anything from a hostage taker to a mouse on speed.
The kit is just $12.95, but does require assembly, so you need to be electronically inclined. You’ll also need to connect either an external speaker or amplifier to hear your modified vocal stylings.
