Symbols in Alerting

dream-flash-flood

I had a dream once – I was walking along a river in China and then an audible alarm emitting from my mobile phone got my attention. When I looked at the screen, surprisingly, a symbol with a red border showing rising water and a human figure running uphill towards shelter, was displaying. Later I […]

Summary of the VoiceICT4D project outcomes

VoiceICT4D project page LIRNEasia, through a stakeholder forum, advocated the Sri Lanka Disaster Management Center (DMC) to move towards a multi-agency situational-awareness platform by creating a register of alerting authorities and then sharing it’s call center and Interactive Voice Response (IVR) system resources for emergency communication. The “Do you Hear Me” video, communicating the need […]

FCC suspends Text-To-Speech for Emergency Alerting

Our findings from the recently concluded Interactive Voice-enabled alerting and situational reporting pilot revealed that Speech-To-Text and Text-To-Speech were impossible to apply with audio over low quality transmission networks (listen to this audio to get a sense how bad it can be). One could sample at much higher frequencies then that produces an extremely large […]

Emulating Speech-To-Text Reliability with ITU Difficulty Scores

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 […]

Crowd sourcing emergency information with Interactive Voice

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 […]

Interactive Voice is Useful and Easy-to-use in managing Crises

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 […]

Noisy interactive voice data cumbersome for extracting categorical information

We recently conducted a training and an exercise with Sarvodaya Community Emergency Response Team (CERT) members in Colombo, Matara, Nuwara-eliya, and Ratnpura Districts. This was an action of the feasibility study to enable Freedom Fone with voice-based emergency data exchange (FF4EDXL). The training involved exposing them to the Freedom Fone interactive voice response system. The […]

License dependencies a hindrance to emergency communication systems

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 […]

Voice for alerting and response

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 […]
