2. Authoring math documents with speech output

  ChattyInfty is an accessible editor for math documents with speech output, 
usable by visually disabled people. Math expressions can be easily input and 
edited using only keyboard, with simultaneous speech output of symbols and 
math structure with key operations.

This software was developed by adding speech output interface to 
"InftyEditor", which interface uses Microsoft speech API. Most of 
InftyEditor functions  e.g. conversion of the edited results into LaTeX, PDF, 
MathML, etc., can be also used in ChattyInfty.  The default file format of 
ChattyInfty is identical with that of InftyEditor (iml). 

Math expressions ranging from secondary education to university level, or 
more-high level ones used by mathematicians, can be easily read and written 
by using ChattyInfty.


3. Combination with Math OCR

In addition, if you installed a math OCR software, InftyReader Version 2.8.0 
or newer, released from <http://www.sciaccess.net/InftyReader/>, you could 
import a recognition result of a scanned image directly into the environment 
of ChattyInfty, which image is taken from a scientific document including 
math  expressions. Thus, combining 
   Scanner + InftyReader + ChattyInfty,
blind people can read directly printed scientific documents including math 
for themselves.
