A few times now I've recorded the normal and emergency checks for a type I'm converting onto as audio files and burnt them to a CD for playing in the car on trips, but it would work just as well for any personal listening device.
I found it a great way to hammer the rote-learnt stuff into my head, and I imagine it would apply to anything you wanted to learn in that way.
You could record stuff on pretty much any computer using its built in mic these days, I'd imagine, or use a more elaborate set up if you want to get your John Laws golden tonsils sound going...
