Patel, Neil, Klemmer, Scott R. and Parikh, Tapan S. (2011): An asymmetric communications platform for knowledge sharing with low-end mobile phones. In: Proceedings of the 2011 ACM Symposium on User Interface Software and Technology 2011. pp. 87-88.

We present Awaaz.De ("give voice"), a social platform for communities to access and share knowledge using low-end mobile phones. Awaaz.De features a configurable mobile voice application organized into asynchronous voice mes-sage boards. For poor, remote and marginal communities, the voice-touchtone interface addresses the constraints of low literacy, language diversity, and affordability of only basic mobile devices. Voice content also presents a low barrier to content authoring, encouraging otherwise disconnected communities to actively participate in knowledge exchange. Awaaz.De includes a web-based administration interface for Internet-connected community managers to moderate, annotate, categorize, route, and narrow-cast voice messages. In this paper we describe the platform's design, implementation, and future directions.

Patel, Neil, Chittamuru, Deepti, Jain, Anupam, Dave, Paresh and Parikh, Tapan S. (2010): Avaaj Otalo: a field study of an interactive voice forum for small farmers in rural India. In: Proceedings of ACM CHI 2010 Conference on Human Factors in Computing Systems 2010. pp. 733-742.

In this paper we present the results of a field study of Avaaj Otalo (literally, "voice stoop"), an interactive voice application for small-scale farmers in Gujarat, India. Through usage data and interviews, we describe how 51 farmers used the system over a seven month pilot deployment. The most popular feature of Avaaj Otalo was a forum for asking questions and browsing others' questions and responses on a range of agricultural topics. The forum developed into a lively social space with the emergence of norms, persistent moderation, and a desire for both structured interaction with institutionally sanctioned authorities and open discussion with peers. For all 51 users this was the first experience participating in an online community of any sort. In terms of usability, simple menu-based navigation was readily learned, with users preferring numeric input over speech. We conclude by discussing implications of our findings for designing voice-based social media serving rural communities in India and elsewhere.

Patel, Neil (2010): Designing and evaluating voice-based virtual communities. In: Proceedings of ACM CHI 2010 Conference on Human Factors in Computing Systems 2010. pp. 2963-2966.

Voice-based virtual communities offer new possibilities for information dissemination and sharing for billions of users who lack access to Internet-connected PCs. As interaction is only through voice, these systems are subject to different design constraints than web-based social software. Through lab experiments and fieldwork, we have identified three key design challenges for voice-based virtual communities: supporting threaded conversations; indexing and searching content; and managing identity. We discuss each of these issues and propose approaches to address them. We also present plans to evaluate the impact of voice-based virtual communities on knowledge access and sharing in rural India.

Patel, Neil, Agarwal, Sheetal, Rajput, Nitendra, Nanavati, Amit, Dave, Paresh and Parikh, Tapan S. (2009): A comparative study of speech and dialed input voice interfaces in rural India. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 51-54.

In this paper we present a study comparing speech and dialed input voice user interfaces for farmers in Gujarat, India. We ran a controlled, between-subjects experiment with 45 participants. We found that the task completion rates were significantly higher with dialed input, particularly for subjects under age 30 and those with less than an eighth grade education. Additionally, participants using dialed input demonstrated a significantly greater performance improvement from the first to final task, and reported less difficulty providing input to the system.
