Changing how VO reads punctuation in iOS

I want voiceover to read more punctuation than it does by default, so I know when there are quotes and things, but I find the way it reads things when set to "all punctuation" virtually unlistenable. Firstly, it doesn't pause at the end of a sentence; it says "period" and then carries on in the same breath, as it were. Secondly, it does pause at commas, but doesn't say the word comma as you'd expect. Having a pause at the commas but no pause at the end of a sentence completely destroys the flow of the text. Third, it reads out all the apostrophes in the middle of words, so "don't" becomes "don apostrophe t", for example. Finally, there are two types of brackets that voiceover calls "left bracket" and "right bracket", leaving no way of distinguishing between the two.

I thought I try using the pronunciation editor to solve these problems. Changing the pronunciation of one of the types of brackets didn't work at all. I finally managed to get it to pause at the ends of sentences in all punctuation mode by changing the word period to period, with a comma after it. I couldn't do anything about the apostrophe issue. I tried things like changing won't to wont, with no apostrophe, and even tried changing the pronunciation of phrases like "won apostrophe t", but neither approach had any effect. Does anyone know of any other ways to get more control over how voiceover reads punctuation in iOS?
