Schematics

VUI

This is a somewhat simplified VUI for the skill and code on the Pi. I simplified aspects due to the fact that there in a game there are so many steps and intents that showing them all will be time consuming but not much more informative. Instead, intents are grouped by category and simplified explanations of the processing is givien.
