Well I couldn't find one myself, but wondered if you had tried the Read Aloud feature of Edge browser or other? I know it's not at all the same but some of the voices are getting a little better I guess.
Here is one copy you could try... just highlight text, right click and select "read aloud". http://www.ccel.org/bible/kjv/preface/pref1.htm It'll work on PDF's too if you already have one downloaded you want to hear.
In the mean time I'll keep my ear out too. I checked on sermon audio.com but didn't find one, and on libravox.org but didn't find one there either. I'm replying so I can get an alert if someone else knows. (but seriously I need a dictionary when I read that so any audio would be too much for me)
