[Blindmath] accessible online math resources

Hi Everyone,

I just wanted to add my own perspective to Ken's comments.  I find that
having a reader (preferably one with at least some mathematical
sophistication) record math to be a fairly decent way to have math
presented.  This is what I do in order to get access to the scholarly
articles I am working on.  After a while, you kind of get into it, and
you can understand a lot from the context and the reader's tone of
voice.  This helps a great deal, in the same way that you can
distinguish, "I read the newspaper every day," (present tense) from, "I
read the newspaper last night," (past tense) -- even though "read" is
spelled the same in both phrases.  You can fairly well tell what is
going on without hearing all of the nuances needed to precisely convey
technical information -- for example subscripts versus superscripts.

On the other hand, I can see the value of using Braille, so that you can
read an equation in it's entirety, without just having a single
character at a time read to you.  For example, I imagine that trying to
learn how to solve "8x+7=12x-3" is probably easier using Braille,
although I can't say for sure.

Anyway, I would like to see a solution so that mathematics printed in
standard formats (such as PDF documents generated by LaTeX) without the
author having originally done some special extra things (that they
probably will never do...)  I do not find MathML to be particularly
useful for complicated expressions, and certainly not for large
documents.  Has anyone on the list ever used or heard of Emacsspeak
and/or AsTeR?  They seem very narrowly oriented, but at least a
reasonable step in the right direction.

Best,

Paul
