Text - to - speech


I am really enjoying using Scrivener (windows XP) after years of
using Final Draft.

One thing I cant work out how to do is Text - to -speech. Is it
possible in the windows version? I have seen that it seems to work
on the Mac version.

At the moment I am outputting to word Docs and using Text to speech there
but wonder if this can be done within Scrivener??

Any help would be great,

cheers, Nick
