I had this same issue after updating my iPhone 7plus to the iOS 13.2.2 After doing the update right before leaving for work at 5am I noticed a bit of trouble using voice text. After getting home I was trying to answer a call from my father and couldn’t hear a thing however my speaker was working to play videos. I done a rest network setting and them had zero signal to do anything I then done it again and everything works fine. My daughter keeps telling me not to do these updates that Apple places glitches in them so we have no choice but to purchase a new phone. After today’s event I believe every word she said.
