Everyone is looking for the killer app that can serve the non-digizen (non digital citizens). There is a lot of hype about smart phones but the practical field level thinkers have realized voice is the better solution. CGNet Swara a citizen journalism project, TCS Innovation Lab’s work on the use of speech for querying railway information1, IITM-RTBI’s Agriculture Information exchange, are a few of many Interactive Voice Response (IVR) enabled solutions that are taking shape in the region. Key reasons for the innovations surrounding IVR are to overcome the problems with key pad entry (pressing W thrice for Y) and traditional English based applications. It doesn’t get easier than pressing a few digits to dial a number and speak your mind or listen to a message.
The P.800 Difficult Percentage (or Difficulty Score) is an International Telecommunications Union Standardization sector recommended method for testing transmission quality in one’s own laboratory. We adopted this method in our feasibility study to enable Freedom Fone for emergency data exchange. The project studied the design challenges for exchanging the Freedom Fone interactive voice data with the Sahana Disaster Management System. This entailed taking situational reports supplied by Sarvodaya Community Emergency Response Team (CERT) members in audible (or speech) forms and transforming them to text.
The usefulness and ease-of-use of interactive voice, with Freedom Fone, for Sarvodaya Community Emergency Response Team (CERT) members to supply incident information was blogged two weeks back. Now the question is “how is all that information put to use in responding to those incidents?”. In here we tell parts of that story. CERT members call one of the four telephone numbers to access Freedom Fone; then press the “reporting” menu item number on their phone keypad to record a “field observation report”.
We conducted controlled-exercises, with Lanka Jathika Sarvodaya Shramadana Sangamaya (Sarvodaya) Hazard Information Hub (HIH) Operators and Community Emergency Response Team (CERT) members. The HIH data center is in Moratuwa. The study using interactive voice, field tested the technology in Colombo, Matara, Nuwara-eliya, and Ratnapura Districts. Figure to the left shows an average ease-of-use of 3.95 and usefulness of 4.
In our current emergency communication research aiming to enable interoperability between Freedom Fone and the Sahana Disaster Management System for disseminating Common Alerting Protocol messages and receiving Situational Reports over voice channels, we came a cross the situation where the 2N UMTS modem license had silently expired. During our silent-test this weekend, in preparation for a drill this week, we noticed that the license had abruptly expired. Unaware of the licensing dependency, the Sarvodaya Hazard Information Hub staff were scratching their heads trying to figure out what had happened. Even though the problem was identified, given that it is the weekend, getting any immediate support from the vendor is questionable. This project: FF4EDXL follows from LIRNEasia’s HazInfo and Biosurveillance research.
Why voice for Sarvodaya’s emergency communication? The experience from the 2011 Foods in Batticaloa and Ampara districts was that Sarvodaya was able to secure aid from various sources by providing the actual ground situation through their web portal. It had images and information of rescue operations, victims, camps, and the devastation. The images and stories came from Sarvodaya head office staff who were deployed to the area. They used cameras, phones, and the internet to relay the ground situation to the Hazard Information Hub (HIH).
