And is it purely 'saying' - verbal - or also writing? I couldn't believe that if it related also to writing, since it is usually significantly more lexically dense (ratio of content words to structural words). This, of course, is one of the distinguishing differences between the two (speaking and writing), and one big thing that children need to learn when figuring out how to 'write' - don't write as you speak!

Hmm, sorry, did I go off topic??
