iPad 2 Air and iOS 9.3

I installed iOS 9.3 two days ago on my iPad 2 air. I now have a problem when using either the on screen keyboard or a Blue tooth keyboard. I use Alex as my Voice for Voice Over. When I type I have Alex speaking when I type letters and numbers. When I use punctuation or space bar the voice changes to Daniel. Plus randomly while ping I hear 'Tn equals spell BTN equals normal'. Or this is what it sounds like.Anyone had similar problems or any ideas to fix it? I have rung Apple and they suggested Resetting to Factory Settings which didn't make a scrap of difference.
