Just found the solution that worked for me having tried all the others suggested here, which had no effect except one.
I went to Settings -->Accessibility, scrolled down to the Services Category (as suggested by others) and turned off what I think is an addon app, 360 Battery Saver & Phone..
It seems to be a gliche/bug in the JellyBean OS and it could be any one of various addon apps that you could have installed ( in my case the 360 Battery Saver) that are causing the problem. To find the add on causing the problem was a case of time consuming trial and error. However once you find the app you added and remove it, it is well worth the effort to get rid of that very irritating and frustrating voice announcing of every page!
Good Luck!
N.B. Be warned! I tried Turning it off by going to "Accessibility" then "Hearing" and then "Turn off all sounds". At first this appears to work but then you realise it really does turn off 'ALL' sounds and you can't hear your phone ringing or notification messages etc.
