It appears I am the only one in the world who has encountered this problem, or according to Google that is! My iPad5 occasionally changes over to "VoiceOver" under Accessibility options for no reason whatsoever or none that I can see anyway! I doubt there is a hot key for this that I am hitting it accidentally and no way do I go to this setting to trigger it off! So why does it do this? It is a pretty rare occurrence, about once or twice a month at most but once it goes to this mode it is extremely difficult to deactivate as the swipe functions no longer work all that well. You can use any combination of fingers but as the Accessibility prompt is "below" the screen size (out of sight) you can't just tap on it to cure the problem. The only way I have found to get out of this mess is to make never ending up-swipes with from one to ten fingers until eventually you crack it and the Accessibility prompt does come into view whereafter it is no problem to strangle the brutes neck! I have Googled the world for an answer but have not as yet found anybody who has had the same issue - velly intellesting no?
