Talk-to-text has been intermittently not working for a months. When you hit the microphone button it might hear one word and then stops typing. You have to hit the button again and continue talking. This occurs on messenger and text app when I use talk to text. Tried Samsung talk to text and it was broken in a different way (duplicate words etc) so I came back to Google. I got a new phone and still have the same problem. Ironically, it is working perfectly as I write this. S22 Ultra & S21 Ultra
