“…Responding to extralinguistic and meta-communicative phenomena, such as the mutual tuning of people's voices and bodies even when they talk using phones and cannot see one another [26], may enhance interactions. For instance, it might improve the efficacy of Interactive Voice Response (IVR), which is currently inferior to interacting with a live operator [31]. Recognising embodied social risks and emotions [18] can also guide decisions on interaction modes; for instance, while at ease using IVR to access football updates, users preferred to input to phone keypads in accessing information about HIV [27].…”

“…Cell-phones offer many new opportunities to people in technology-sparse regions but they may also amplify gaps between oral and literate users and this has motivated recent efforts to develop asynchronous voice platforms for rural settings where literacy is lowest. Such efforts include interactive voice applications and services for cell-phones to record and access content produced locally, or by authorities or NGOs [19,27,31,39] or participate in citizen journalism or online social networks [25,29]. However, there are few empirical studies [29] and design tends to be oriented by theory that contrasts the mental functions of oral and literate people, not by practices in social situations.…”

Abstract. Designing for oral users in economically poor places has intensified efforts to develop platforms for asynchronous voice. Often these aim to assist users in rural areas where literacy is lowest, but there are few empirical studies and design tends to be oriented by theory that contrasts the mental functions of oral and literate users, rather than by local practices in social situations. We describe designing an Audio Repository (AR) based on practices, priorities and phone-use in rural Africa. The AR enables users to record, store and share voice files on a shared tablet and via their own cell-phones. We deployed the AR for 10 months in rural Africa and illiterate elders, who have few ways to use free or low-cost phone services, used it to record meetings. Use of, and interactions with, the AR informed the design of a new prototype. They also sensitized us to qualities of collective sense-making that can inspire new interactions but that guidelines for oral users overlook; such as the fusion of meaning and sound and the tuning of speech and bodily movement. Thus, we claim that situating design in local ways of saying enriches the potential for asynchronous voice.Keywords: Oral users, Rural Africa, Asynchronous voice, Social media. IntroductionMost of the world's 800 million illiterate adults live in economically poor regions; in fact, interpolating Worldbank indicators, in Africa fewer people can read and write than there are cell-phone subscriptions [23]. Cell-phones offer many new opportunities to people in technology-sparse regions but they may also amplify gaps between oral and literate users and this has motivated recent efforts to develop asynchronous voice platforms for rural settings where literacy is lowest. Such efforts include interactive voice applications and services for cell-phones to record and access content produced locally, or by authorities or NGOs [19,27,31,39] or participate in citizen journalism or online social networks [25,29]. However, there are few empirical studies [29] and design tends to be oriented by theory that contrasts the mental functions of oral and literate people, not by practices in social situations. In this paper we describe a system we deployed in rural South Africa to enable users to record, store and share voice files for free. We aim to show that situating design in local ways of saying can inspire new interactions for asynchronous voice; thus, we start by claiming that theory currently orienting design for oral users omits factors that can prompt ideation.

“…Use of local language might turn out to be one of the primary requirement for designing phones in India. Researchers have also found that in developing nations like India, error rates in health care scenario while collecting through mobile phones is highest (4.5%) through electronic forms and lowest (0.45%) when the information is collected through voice [14]. Such studies initiate interesting discussion on voice vs text as medium for communication in Indian context.…”

Mobile phones have emerged as truly pervasive and affordable Information and Communication Technology (ICT) platform in the last decade. Large penetration of cellular networks and availability of advanced hardware platforms have inspired multiple innovative research opportunities in mobile computing domain. However, most of the research challenges have focused on typical scenarios existing in the developed economies. Using the healthcare as an application for mobile computing, we present research challenges and novelties in mobile computing domain that take account for differences between developing such as India and developed economies based on commonly available mobile platforms, communication cost, differences in user behavior and acceptable societal norms, among others. With localization being a critical component of various mobile systems, we present early results for the application of GPS-less localization that highlight the corresponding differences in Indian context.

“…15 On the other hand, the corresponding system in Afghanistan (M-Paisa) found that a voice-operated system was necessary. There is some evidence that voicebased data collection systems may result in greater accuracy (Patnaik 2009), clearly an important factor where critical data, for example on health care, is being collected.…”

Debates as to the potential role of new Information and Communication Technologies (ICTs) in monitoring the wellbeing of vulnerable groups is often bedevilled by the failure of two principal actors – social researchers and technical experts – to address the other's concerns or even to use language that is comprehensible to the other side. The aim here is to unpick some of the technical language relevant in this context and provide a brief introductory guide to some aspects of the current, rapidly changing and highly diverse ICT environment.
