Voice search for development

Abstract

In light of the serious problems with both illiteracy and information access in the developing world, there is a widespread belief that speech technology can play a significant role in improving the quality of life of developing-world citizens. The authors review the main reasons why this impact has not occurred to date, and propose that voice-search systems may be a useful tool in delivering on the original promise. The challenges that must be addressed to realize this vision are analyzed, and initial experimental results in developing voice search for two languages of South Africa (Zulu and Afrikaans) are summarized.
