A user made software modification that allows almost complete use of Canon cameras through voice control.
“It allows nearly complete control of the software by voice. Everything from focus and shooting to aperture, shutter, ev, and white balance. It even lets you open Live View and Zoom and access the up/down/left/right buttons on the zoom screen all by voice.”
