I am unable to use Mac dictation; the microphone is recognised and, at times, does write some words. The words are 'tamb', 'tamb', 'tamb', or the names of random people. The dictation has nothing to do with what I dictated. I can use online dictation, such as Google Dictate, but the Mac dictation does not work.

I have also downloaded MacWhisper and other apps that use the Whisper engine, but it seems anything that uses the native Mac dictation service will not work, but online is fine.

I have tried every fix I can think of, but without success. Does anyone have any ideas? Other than the fixation, the OpenCore patch breathed new life into an old Mac.

Thanks to the OpenCore team for good work.
