Russ,I don't think there is any "software" that you could download for the Ipod nano.
The Ipod nano has a checkbox where you can enable speech. Of course, after connecting the Ipod to your computer and being on Itunes, you can search for that accessing the menus. That wasn't a great explanation but it's a starting point.
