How do you punctuate using Siri?

Hey there, and welcome to Apple Support Communities, TxGringo!

I see you have questions about using punctuation with Siri, and I’d be happy to help.  Using Siri for punctuation is the same as using punctuation with Dictation.  You can read more about the process under “Use punctuation and formatting” at: Use Dictation on your iPhone, iPad, or iPod touch - Apple Support

Specifically, you'd want to verbalize the punctuation while speaking. So you'd want to end the sentence by saying "period" or add a comma by saying "comma".

I hope that helps, and thanks for using Apple Support Communities. Take care!
