Same. iOS 17.1.2 on iPhone 14 Pro. Siri just stops talking in the middle of reading texts as well as in the middle of reading back what I dictated to it when I ask it to read back to me what I said. I turned off press side button for Siri as well, because that was getting activated at random times since the update. It’s bad! I can’t use voice to text when I am traveling at all now, and there is no way I am going to touch my phone to try to send texts when I am on the road, as that is illegal in most states. It degrades the usefulness of this expensive device.
