Vocal Joystick

University of Washington researchers have developed a software known as "Vocal Joystick" for controlling the mouse using your voice. Saying "ooo" Takes the cursor down, while saying "ahh" moves it to the upper right. They've specifically developed this to help disabled people. The Vocal Joystick software will need only a PC microphone to work. Several applications have been tested using the software, including video games and robotic arm operation.
