Necessities for Math-Access Tools with Speech

Some new points that should be required in assistive tools for print disabled people to access math/science with speech output are discussed. The manner of “aloud reading” should be switched to the appropriate one according to the characteristics of a reader’s disability; blind users need a different manner than dyslexic users. Furthermore, the ambiguity of math expressions requires assistive tools to offer a method to assign an appropriate reading flexibly to those expressions according to context. In our accessible math-document editor, those features are really implemented. Combining it with our math OCR software, one can easily convert a math/scientific document in print or PDF into accessible e-books in DAISY or EPUB.
