I don't want to appear contradictory, but I strongly disagree with the statement that MathML is not suitable for speech. A proof of this is already available in MathPlayer. MathPlayer is a free download for displaying MathML in IE. In version 2.0, which was released a few months ago, Design Science included a demonstration of MathML-to-speech technology. Design Science worked with major screen reader vendors so that recent releases of JAWS, Window-Eyes, and HAL all work seamlessly with MathPlayer to read MathML -- both presentation and content MathML. For those not using a screen reader, there is a "Speak Expression" right button menu item that can be used to speak the MathML. We are working with other vendors to incorporate synchronized speech/highlighting into high-end magnifiers that use speech and learning disability tools. This work was funded in part by a grant from the NSF, and we fully understand that the speech output can and should be improved from the what is part of MathPlayer 2.0. We also understand that navigation of large expressions and generation of various braille math codes such as Nemeth code are important and we are working on these aspects of the project. For more information, see http://www.dessci.com/en/reference/accessibility/ and http://www.dessci.com/en/products/mathplayer/tech/accessibility.htm I recommend downloading MathPlayer from http://www.dessci.com/en/products/mathplayer/ before reading the later URL as it contains MathML. If you have any questions or suggestions for improvement after trying out MathPlayer, please feel free to contact me.
