Opera browser uses voice commands. Now I’ll have to actually test it to see how well it works. The Vocal Joystick would work on all software that uses a mouse device. I thought something like Dragon Naturally Speaking can command more than the voice recognition software?

University of Washington researchers are developing a new “Vocal Joystick” interface to make software more accessible for people who don’t have use of their hands or arms. The software converts simple vowel sounds and other intonations into cursor movement. The louder the sound, the faster the cursor moves. Saying “K-Ch” represents a mouse click and release….

“A lot of people ask: ‘Why don’t you just use speech recognition?'” (electrical engineering professor Jeffrey) Bilmes said. “It would be very slow to move a cursor using discrete commands like ‘move right’ or ‘go faster.’ The voice, however, is able to do continuous commands quickly and easily.” Early tests suggest that an experienced user of Vocal Joystick would have as much control as someone using a handheld device…

“The tool’s latest developments will be presented this month in Tempe, Ariz. at the Assets Conference on Computers and Accessibility.

Vocal Joystick detects sounds 100 times a second and instantaneously turns that sound into movement on the screen….

Versions of Vocal Joystick exist for browsing the Web, drawing on a screen, controlling a cursor and playing a video game. A version also exists for operating a robotic arm, and Bilmes believes the technology could be used to control an electronic wheelchair.” […] http://uwnews.org/article.asp?articleID=37134
