Why does Dictation stop immediately on my MacBook Air?
Dad's MacBook Air (2019/Sonoma 14.7.1) is giving him fits. He's essentially dependent on dictation, having lost a lot of dexterity in one hand. Since maybe a week or two back, when he double-presses fn to trigger dictation, he gets the start tone immediately followed by the end tone. I've tried switching off Bluetooth without success. Any ideas?
