My voice to text was not working (I tapped the mic icon on the keyboard, but it would not listen to my voice), but I finally solved the problem. In case others have this issue, here's what I did. I thought it's probably not an app problem, as the issue showed in many apps. It also probably was not a keyboard problem, as I had the issue on 2 keyboard apps.
I noticed sometimes I'd get a popup window that said something like, "Google App has stopped". I don't even use Google App, so why is that showing? Maybe the keyboard uses Google App.
So I did: settings; apps; application manager; Google App; force stop. That didn't seem to do anything, as the button was still active (not grayed out). So from there, then I did: storage; clear cache and manage storage; clear all data. That worked! You don't realize how much you "need" voice input until you lose it. I felt I was back in the Stone Age. But now it works, yea!
