Beautiful Code is a collection of essays on software design, with all proceeds going to Amnesty International. It includes a chapter on the use of Lisp advice to speech-enable Emacs --- AKA Emacspeak. I'll eventually publish an HTML version of my article on the emacspeak Web site. In the meantime, I highly recommend the complete book --- which if you need an accessible version can probably be obtained from organizations like BookShare.
