I agree with others who posted: you dont have to say anything if you dont want to.
some meetings are spent taking turns reading out of the big book. i found this a good way to get more comfortable with speaking since i was only reading out of the book and didnt have to think of what to say.
some other meetings you will find that a few people take turns reading literature and then everyone takes turns talking about their interpretations of what was read and/or how it relates to them. but then again, you can politiely excuse yourself from speaking when it comes your turn
