This video game gives your thumbs a rest while stretching those vocal chords. The pair of microphones seen above control the video game on the LCD display. Saying “Biu” will launch a projectile while “ahh” adjusts the flight path. The system was developed by [Tian Gao] as a final project for his ECE 4760 course at Cornell University.
The inputs are common computer microphones connected to some processing circuitry which he built on a piece of protoboard. This consists of some RC filtering and an LM358 opamp to get the signal ready for use with the ATmega1284. There is only one ADC on that chip so [Tian] alternates sampling from the microphones by using the multiplexer built into the chip. The video signal itself is an NTSC composite signal. To facilitate a reasonable frame rate he uses graphics that are packed in multiples of 8-bits. All in all this allows him to create a 160×200 pixel display.
All of this makes the game sound a little dry, but we dare you to listen to the video clip after the break without cracking a smile.
Why couldn’t Nintendo do this with the Wii? Think of the possibilities….FPS’s where you have to say ‘pew pew pew’ to fire the guns….Mariokart where you control the throttle by making race car noises….
That reminds me of a speech therapy game I used back in the day. The therapist would pick two sounds, then the game would be to steer a canoe down a river using one sound to go left and the other to go right. That was back in ’96.
They had this with the NES, though it didn’t work so well ;P
FIRE! FIRE! FIRE!

There was a side scrolling iPhone game a number of months ago that used the same kind of instructions. It was called PAH!
Brings to mind TV-POWWW that I used to watch on KTVU Channel 2 back in the olden days: http://en.wikipedia.org/wiki/TV_Powww
