The Voice-Stick: A Voice Controlled Sega Joystick

Children, and adults, who have speechor hearing disabilities are often given exercises by speech therapists that involve making a lot of, frankly boring, repetitive noises.The patient may also feel a bit silly while uttering these noises to a blank wall.How much better it would be if one could combine both therapy and pleasure by using these noises to control an exciting and interactive video game.One could do one's speech exercises, and relieve ones stress.by shouting at Sonic The Hedgehog or Super Mario!The purpose of this project was to design a voice controlled device that could replace the joystick of a standard.and therefore readily available.game machine.This would allow both a cost effective implementation, and access to a wide variety of games to practice one's voice on.The paper will describe the results of this project.It will focus particularly on the problems associated with interfacing speech parameter extraction circuitry with the interface protocols of the game machine.
