Title: Towards an information ecosystem for animal disease surveillance using voice services Authors: Sharma Grover, A; Van Huyssteen, G; Calteaux, K Abstract: In this paper we introduce a solution for disease surveillance and monitoring in the primary animal health care (PAHC) domain that uses inbound voice-based services and voice- and text-based outbound services for connecting rural veterinarians and livestock owners with a PAHC service provider. We describe our findings from the ongoing pilots, where we found that it is crucial to close the loop between data collection and information dissemination.

Title: The relationship between automatic assessment of oral proficiency and other indicators of first year students' linguistic abilities Authors: De Wet, F; Niesler, T; Van der Walt, C Abstract: Academic literacy proficiency is key to the success of a student at university. Currently, the large-scale assessment of language proficiency, particularly at higher education levels, is dominated by reading and writing tests because listening and speaking skills are thought to be too difficult to evaluate. The application of automatic speech recognition (ASR) techniques in the automatic assessment of these skills is one of the ways in which the logistical challenges associated with testing listening and oral proficiency can be addressed.

Title: Audio pacemaker : Walking, talking indigenous knowledge Authors: Bidwell, NJ; Winschiers-Theophilus, H Abstract: There are mismatches between indigenous knowledge (IK) and the media, representations and abstractions used to gather and depict IK in an increasing number of projects in Africa. We describe new studies that continue our efforts to digitally extend local IK pedagogy in healing with plants in Namibia. We used two novel, technological tools to explore narrative construction and provoke reflection by IK holders and researchers on their interactions with technology. Our tools and methods sought to reduce emphasizing vision and elicit ‘ongoing’ qualities in making and sharing knowledge. Our analyses show the importance of activity, kinetic relationships and rhythms in walking and talking in knowledge practices. Thus, we advocate mixing modalities in gathering and depicting IK, increasing focus on oral and multi-sensory interfaces and walking in design processes. We also present a design concept that supports links between talking and walking. Description: Copyright: 2012 ACM. This is an ABSTRACT ONLY
