They would like to know if there is a facility to make the output of a LaTeX file understandable by the visually impaired? The text part doesn’t seem to be a problem; it’s the graphics and similar structures that present difficulty. Is there anything available?

Actually, the text part can be improved by using CMAP and other nifty things to ensure that a^2 + b^2 = c^2 comes out as something more intelligible than a two plus b two equals c two. See ``tagged pdf'', e.g., : http://tex.stackexchange.com/questions/579/how-to-create-tagged-pdf

For graphics, there are similar options: http://tex.stackexchange.com/questions/75102/need-alt-text-for-images-in-pdf-for-screen-readers

This answer also suggests pdfcomment: http://tex.stackexchange.com/questions/19279/latex-accessibility and this may also help: http://tex.stackexchange.com/questions/32609/latex-to-braille

Looking back through the archives there's been some discussion of voice recognition, &c. in the past, e.g., Karl Berry's response:
