If a person has learning difficulties due to developmental disabilities or other reasons, learning may be facilitated by using tablets or other devices to add phonetic cues above kanji characters, to use text-to-speech, and/or to enlarge the image of materials. In the“ Survey and Research on Efficient Production Methods for Audio Teaching/Learning Materials” of the Ministry of Education, Culture, Sports, Science and Technology-Japan, six organizations have been entrusted with the project and are providing the teaching materials to children. One of such organizations is Hiroshima University. We used to call the teaching material “e-Pat” until 2021. It came with functions of viewing pages as they read the textbooks (original mode) and reading aloud on the text-only screen (reflow mode). To aim for efficient production and effective dissemination of the e-Pat, the users’ school officials and parents/guardians were given questionnaires on the method of providing the material, how well users learned using the material, and additional functions desired for such materials. The e-Pat was most frequently used during classroom lessons, especially in normal classes. Many also felt the e-Pat application process (applied by schools) to be easy. Many also felt that the e-Pat helped them read sentences and Kanji characters. Many also requested to add text-to-speech functions and phonetic cues above Kanji characters in the original mode. Improved text-to-speech materials according to the needs of users are desired.
