Driving me nuts. Siri & Voice-to-Text Dictation not working for iOS search, Note App, Messages App, and all other apps that use the microphone button to record dictation. Microphone hardware works fine for recording videos and facetime, so not the hardware. I uninstalled and reinstalled keyboard languages (English US, UK, German), toggle Siri on/off, reboored, reset the network, reset all... did all the recommended methods, but nothing worked to fix this on my iphone XR. Went to the Apple Store in Boston -- they said it could be the VPN, so I uninstalled all VPN settings -- still did not work. Siri & Dictation work fine on my ipad pro still, so has to be the iOS 16.0.x updates that screwed it up. Cannot do anything except wait for an iOS update to hopefully fix this. Bummer about doing the complete phone reset is that I've lost all the WiFi passwords for all the places previously registered in my phone.
