WWTW: the world wide telecom web
TLDR
WWTW is a network of interconnected voice sites that are voice driven applications created by users and hosted in the network that has the potential to enable the underprivileged population to become a part of the next generation converged networked world.Abstract:
The World Wide Web (WWW) enabled quick and easy information dissemination and brought about fundamental changes to various aspects of our lives. However, a very large number of people, mostly in developing regions, are still untouched by this revolution. Compared to PCs, the primary access mechanism to WWW, mobile phones have made a phenomenal penetration into this population segment. Low cost of ownership, the simple user interface consisting of a small keyboard, limited menu and voice-based access contribute to the success of mobile phones with the less literate. However, apart from basic voice communication, these people are not being able to exploit the benefits of information and services available to WWW users.In this paper, we present the World Wide Telecom Web (WWTW) --- our vision of a voice-driven ecosystem parallel to that of the WWW. WWTW is a network of interconnected voice sites that are voice driven applications created by users and hosted in the network. It has the potential to enable the underprivileged population to become a part of the next generation converged networked world. We present a whole gamut of existing technology enablers for our vision as well as present research directions and open challenges that need to be solved to not only realize a WWTW but also to enable the two Webs to cross leverage each other.read more
