Welcome to Android Central! Does it freeze up for a while, or does it just pause for a bit? Does the rest of the screen register touches?

Try booting into Safe Mode, which prevents 3rd party apps from starting up initially. If that behavior goes away, then something you installed might be causing the problem. Start opening your apps one by one, and check the typing after each app start, to see if the problem recurs.
