Chris,
You may like to point them in the direction of a rockboxed iriver H1xx.
Rockbox has voiced menus (ie an audio file is played back whenever a menu is selected, or it is audibly spelt),
however unfortunately the recording screen has not yet been voiced. There are however only a few options on that screen so they *may* be able to feel it out (I manage to do it for stealth recording anyways)
I've just confirmed with the Rockbox developers that it is possible for them to voice the recording screen in future, however it will interrupt monitoring (I wouldn't imagine this would be a big deal). So hopefully the developers will look at that sooner rather than later.
If you'd like to give them a nudge, you may like to put in a feature request for it here:

edit; oh, and it transfers via USB.
