Turned on voice accessiblity feature now can't log into phone

I turned on the voice accessibility feature. I didn't like it because of the delay. I want to turn it off but couldn't get back to Settings so I rebooted the phone. Now it thinks I'm using the voice accessibility feature and it won't accept my passcode. When I type my passcode nothing happens. After several attempts I once was able to enter the code with the voice feature reading it back to me but it wouldn't log in. It's like it doesn't register that I'm entering it. The system says I need to use my passcode to change the setting. No kidding. How can I fix this if I can't get in? I've looked up hard reboot but all material just brings it back to the same place. I think I need a total refresh but I don't know how force that without accessing the phone. Ideas?

thank you
