The slides that go with my Assistive Technology Demo as given to WordCamp Bristol on 13th May 2017. I demo Dragon NaturallySpeaking - voice recognition software, and NVDA - a screen reader. The slides introduce the demo - and contain a few of the common commands for each of the two pieces of software demoed.
