Tell that to the Authors Guild:

okay, thanks.
however, to clarify, i am sure that don knuth
would have no problem with someone using an
editor with voice output on the texbook file.
his specific prohibition is against typesetting
it.  however, the file does have this (more
% The file is distributed only for people to see its examples of TeX input,
% not for use in the preparation of books like The TeXbook.
% Permission for any other use of this file must be obtained in writing

i will inquire whether a "blanket" authorization
can be made for the case of blind users; i know
that permission has been granted in the past.

note to paul stanley:
victor eijkhout's book, "tex by topic", is
available from ctan in latex form.  there are
several files, located in
http://www.ctan.org/tex-archive/info/texbytopic/
although this really goes into the guts of tex,
is not in any way introductory, and doesn't
explain math usage, it might still be of
interest.  start by looking for "preface";
the book starts with a copy of the gnu license,
which isn't of \emph{tex} interest.
