You can use Windows Voice Access with SpeedCast. You can perform basic commands with your voice. In addition, SpeedCast now has audible feedback when tap-testing. You will now hear audible sounds for a good hit, a bad hit, a double hit, along with too hard or too soft hits. You do not have to be in view of the computer screen to see if you made a good hit. This will be especially helpful in a larger machine where the computer cannot be positioned within view.
