Article: A Comparative Study of Speech and Dialed Input Voice
Interfaces in Rural India
Authors: Neil Patel, Sheetal Agarwal, Nitendra Rajput, Amit Nanavati, Paresh Dave, Tapan S. Parikh
Summary: The authors of this article took it upon themselves to test out two different interfaces for providing agricultural information to remote farmers in India, most of whom were illiterate and had never used a PC before. The two different interfaces that would be used to provide agricultural information to the farmers were both phone systems, but one used speech recognition in order to navigate through a menu, and the other used dial tones. They took a mobile phone and a dialpad to several homes of the farmers who were to evaluate the phone systems, and took measurements of error rates, facial expressions that would indicate frustration, etc, and took a post-use questionnaire in order to gauge user enjoyment of the system.
Shaun's Opinion: The first thing that struck me about this article is how it is very confusing, right from the get go, until you stop and think about what they are saying. The authors provide very little background on the work they are doing, and don't even delve into the meanings of most of the acronyms they use. However, I do applaud their work for trying to find the most cost effective and easiest to use (especially among a less educated user base).
