I am having the same problem with the Tap To Speak screen locking up on the screen. It started yesterday, 9/26/15, and is a real PAIN. If I power down and power up the Samsung S4 the screen is okay -- until I use the speech to text option.
I uninstalled the updates to the Google text to speak app only- not the regular Google app - as suggested, and so far no more freezing and no other problems created. Thanks very much for the suggestions!
I spoke too soon. It's happening again. :-(
That's very interesting--I had meant the Google App (which is responsible for the Google Search widget and Google Now, among other things), because it was recently updated. I don't recall the Text-to-Speech app being updated recently. But it's certainly possible that the update to the Google App somehow caused it to interact poorly with the Text-to-Speech engine, contributing to the freezes. It would be interesting, for those of you who are having this issue, to see what happens if you first uninstall the updates to Text-to-Speech. If that doesn't help, then go ahead and uninstall updates to the Google App (and you can probably re-update Text-to-Speech again).
For those of you who have already uninstalled updates to the Google App, try re-updating it, and then uninstalling updates to Google Text-to-Speech.
