A LaTeX to Braille Conversion Tool for Creating Accessible Schoolbooks in Austria

Using NLG for speech synthesis of mathematical sentences

“…Since Braille is not a universal standard, different converters have been developed. The most widespread include conversion from LaTeX to Japanese Braille (Hara et al, 2000), to Nemeth code mostly used in English speaking countries (Papasalouros and Tsolomitis, 2015), to Marburg code mostly used in German speaking countries (Murillo-Morales et al, 2016) and from MathML to Spanish, French and Italian Braille codes (Soiffer, 2016). Nonetheless, Braille cannot support all the notations that can be expressed through LaTeX or presentation MathML (e.g., category theory, computational logic) and it has not a mechanism to introduce new notations hence the converters have a number of limitations.…”
