Dictation problems

Since the latest install, (or at least I believe it‘s since the latest 116.1.2, as they did two in quick succession) …. dictation has been a nightmare! First, it keeps putting punctuation in, but it’s in the wrong places, so I have to backtrack to keep undoing the capital letters and taking out the .’s and commas and secondly it’s just not as accurate as it used to be (way way, worse), anybody found a fix for this?!
