Abstrakt

The paper presents the current state of the ongoing project “Automatic Reading of Educational Texts for Vision Impaired Students” (ARET). The project aims at an innovation and enhancement of schooling of vision impaired students and also at a facilitation of their self education. The project is solved at the University of West Bohemia (UWB), Department of Cybernetics, in cooperation with The Primary School and the Kindergarten for the vision impaired in Pilsen. Within the project, a specially designed system for automatic reading of educational texts for vision impaired students is developed. Teachers use the system for a preparation, management and administration of educational texts. In order to facilitate the maintenance of the final system, client-server architecture was chosen. The system is based on the Symfony PHP framework. The educational texts are available to students via system's front-end; they are read aloud by means of computer speech synthesis (more specifically, using a text-to-speech engine developed at the UWB). The access to the system is highly configurable; different rights for editors, students and others can be easily set up. With respect to both the purposes of the ongoing project and the main partner (the primary school), the educational texts concentrate on Mathematics and Physics (ISCED 2 level). Hence, the presence of mathematical and physical formulas has to be dealt with, both in the phase of a creation of educational texts and in the phase of automatic reading of the texts. Automatic processing of the formulas, including a transcription of symbolic notations to corresponding word forms and automatic reading of such texts, presents a challenge to the current text-tospeech technology. Despite the current focus on primary-school subjects, the system is capable of reading any texts, including more advanced texts like tertiary level of mathematics, etc.
