The spoken web application framework: user generated content and service creation through low-end mobiles.
ABSTRACT While the word 'accessibility' seems to require a new definition in the context of making Web available in developing regions, we propose to expand the definition of 'Web' itself in the same context. The prevalent definition of Web as a system of interlinked textual documents available on the Internet and accessed through a web browser, needs to be modified to include new types of hyperlinked content and new access mechanisms. Spoken Web is emerging as an alternate web for the underprivileged by breaking barriers of illiteracy, affordability and local languages. It is envisioned as being complementary to the existing Web and navigable entirely through a voice based interface using an ordinary telephone. In this paper, we present Spoken Web Application Framework (SWAF) -- a framework for enabling creation of sites in Spoken Web through a simple voice interaction over an ordinary phone call. This unique novelty of SWAF provides an extremely simplified service creation ability using voice interaction rather than through programming by IT experts thus enabling a new software development paradigm. It is meant to be a platform for making the power of Web technologies become accessible to the next billion IT users of the world. We present the architecture, design and implementation of the SWAF framework.

ABSTRACT: The development of user interfaces (UIs) is one of the most time-consuming aspects in software development. In this context, the lack of proper reuse mechanisms for UIs is increasingly becoming manifest, especially as software development is more and more moving toward composite applications. In this paper we propose a framework for the integration of stand-alone modules or applications, where integration occurs at the presentation layer. Hence, the final goal is to reduce the effort required for UI development by maximizing reuse. The design of the framework is inspired by lessons learned from application integration, appropriately modified to account for the specificity of the UI integration problem. We provide an abstract component model to specify characteristics and behaviors of presentation components and propose an event-based composition model to specify the composition logic. Components and composition are described by means of a simple XML-based language, which is interpreted by a runtime middleware for the execution of the resulting composite application. A proof-of-concept prototype allows us to show that the proposed component model can also easily be applied to existing presentation components, built with different languages and/or component technologies.01/2007;
Conference Proceeding: Voicepedia: towards speech-based access to unstructured information.[show abstract] [hide abstract]
ABSTRACT: Currently there are no dialog systems that enable purely voice-based access to the unstructured information on websites such as Wikipedia. Such systems could be revolutionary for non-literate users in the developing world. To investigate interface issues in such a system, we developed VoicePedia, a telephone-based dialog system for searching and browsing Wikipedia. In this paper, we present the system, as well as a user study comparing the use of VoicePedia to SmartPedia, a Smartphone GUI-based alternative. Keyword entry through the voice interface was significantly faster, while search result navigation, and page browsing were significantly slower. Although users preferred the GUI-based interface, task success rates between both systems were comparable - a promising result for regions where Smartphones and data plans are not viable.

ABSTRACT: The power of the Web revolution came with making every-one a publisher, rather than just a consumer of information. However, as the prevailing interfaces to the Web require a high degree of literacy and full-fledged computer access, much of the world's population lacks the skills or resources needed to create online content. In this work, we aim to lower the barrier to sharing local information via an Audio Wiki: a repository of spoken content that can be accessed and modified via a low-cost telephone. Because content is in purely audio form (from entry to playback), the system is accessible to the illiterate and naturally supports any local language. By enabling poor and illiterate users to create lo-cal stores of information, we envision broad applications in agriculture, health, government, and entrepreneurship.
