Siri doesn’t understand my punctuation.

Siri auto-dictation won't insert a period in message. It spells it out. Other punctuation works fine.

If I use auto-dictation to speak directly to Siri, a period will be inserted appropriately. In any other format, Siri spells out the word rather then inserting a period.

I saw in a post from a couple of years ago to make sure Language is set to English and Region to United States. I’ve done that and still have the problem.

didn't have this problem until 13. I even bout a new phone - same issue.
