The site I came across is http://www.odiogo.com/ and it says it converts text to speech on blogs. I have yet to try this but thought it looked interesting. I think it could be useful for making blog entries more user friendly for all of our students. I have a blogging assignment coming up soon and will try it out and post a followup but thought I would put it up here as well.
