I think that this method is probably quite accurate. Whenever I'm writing a fic, whether it is speech or just description, I always read it aloud to myself to make sure it sounds right and that I have the correct punctuation in the right places - like imagining someone is reading the story to you.Eccentric One wrote:
I have to agree. Although my reasoning for it may be a bit non-grammatical. I was originally trained in theatre as an actor. Punctuation was the big, bold-faced clue as to how the author wanted the lines to be pronounced. Commas were a short breath. Periods a break in the thought. Ellipsis and hypens were "pregnant pauses." Semi-colons were treated the same as a sentence-ending period.
Punctuation marks in a script, to an actor, indicate the phrasing the author indended the lines to be delivered with. While that may or may not be grammatically correct, it does apply (to some degree) to fan fiction. Punctuation gives us the feeling of how the words should sound when spoken.

One thing that I think people can miss is that if someone is addressing somebody else, you always need to put a comma (a pause)before saying their name - for example:
"Is it raining, Max?" where the person is asking Max if it is raining.
If there was no comma, it would read "It is raining Max?" and the person would be then asking if Max himself was raining (as in raining cats and dogs).
Anyway, that's just something I've noticed
