On a new 2021 Macbook, with macOS Monterey 12.0, I used Dictation frequently.
A few days ago Dictation just stopped working completely. The microphone overlay pops up but there is not movement in response to sound and no words are generated.
I thought it might be a microphone input issue but checking the Sound settings, the microphone is selected and working great.
I have turned it on and off as suggested by this question and answer. However doing the on off restart dance has not fixed the issue for me.
Also found this AskDifferent question where Dictation stops working intermittently. However for me restarting has not fixed the issue.
I opened the Console app and did see an error when I tried using Dictation. Don't know if that is helpful or not, I don't know what I am looking for.
How can I fix Dictation so it works again?
