Incorporating Speech Synthesis in the Development of a Mobile Platform for e-learning.

Abstract

This presentation and accompanying demonstration focuses on the development of a mobile platform for e-learning purposes with enhanced text-to-speech capabilities. It reports on an international consortium project entitled Mobile E-learning for Africa (MELFA), which includes a reading and literacy training component, particularly focusing on an African language, isiXhosa. The high penetration rate of mobile phones within the African continent has created new opportunities for delivering various kinds of information, including e-learning material to communities that have not had appropriate infrastructures. Aspects of the mobile platform development are described paying attention to basic functionalities of the user interface, as well as to the underlying web technologies involved. Some of the main features of the literacy training module are described, such as grapheme-sound correspondence, syllabification-sound relationships, varying tempo of presentation. A particular point is made for using HMM (HTS) synthesis in this case, as it seems to be very appropriate for less resourced languages.
