Ohhh good idea Paul.
Tagging on to what Labby said, in the UK talking newspapers (
http://www.tnf.org.uk/ ) are always looking for volunteers to record audio versions of newspapers and magazines.
I'm sure there must be similar organisations in the US, but it is late, and I'm too tired to find out more, your google-fu is probably as good as mine
The other thing I thought about was audio for Wikipedia and Wikitionary
[url=http://en.wiktionary.org/wik...onary.org/wiki/Help:Audio_pronunciations [/url] and/or http://en.wikipedia.org/wiki/Wikipedia:WikiProject_Spoken_Wikipedia
I'm sure I could think of more things, but it's late, but that might give you some ideas...
