I haven't had a chance to follow up on those links, but just wanted to mention that..

Festival may be able to provide the alternative audio file[1], or with a library of audio files that spell out letters (such as from asterisk[2]), one could join files to produce the alternate audio.

Thanks, Torben. As i could read about it festival works with MBROLA system and the voices database that project already has. It sounds very interesting.

Here in Brazil one of our federal universities - Universidade Federal do Rio de Janeiro - is developing a software called SINAL - Sistema Interativo de Navegação no Linux (Linux Interactive Navigation System) to enable web accessibility to users who are blind. SINAL is going to use MBROLA as far as i know.
