2.3.8.2 Get Voice Response (#X)

The Get Voice Response command (#X) is a copy of the Get Key Response (#R) command. It pauses Cogsys until the subject makes a voice response into a microphone. Normally, there are three voice responses which are recognized: "bes", "bo", and "space". "bes" is the "yes" equivalent, and this returns the "/" key. "bo" is the "no" equivalent, and this returns the "z" key. "space" returns the "space" key. Then, like #R, #X writes the key pressed and the reaction time in milliseconds to output, followed by a newline. It updates Cogsys variables 7 and 5 with the key and time, respectively.

Currently, the Get Voice Response command is in parallel with the keyboard. Pressing "/" on the keyboard is equivalent to saying "bes". For this reason, it is possible to break out of #X when the "@" key is entered.
