The means by which they are generated is a TCL/TK program:

  http://wiki.tcl.tk/21708

The first half of the generator program is a description of the of the
syntax as a sequence of TCL formatted data structures.  The rest of the
program then uses those to generate the graphics.

It should be possible to replace/augment the generator portion with
something that outputs a textual format suitable for screen readers.  If
you are the developer type yourself then it is a simple matter of
programming :-)

Failing that you should be able to get someone else to help who is
familiar with the screen readers and can work with you to get something
helpful.

Failing that you could create sample output yourself and ask here if
anyone can help.
