BEIJING, Nov. 28 (Xinhuanet) -- A software that allows a computer to listen like a human to detect anger with a high level of accuracy has been developed by Sound Intelligence.
The software is Sigard Sound Intelligence, and when combined with closed circuit TV systems it can quickly notify security personnel about loud, angry people in public transportation, outdoor public spaces, nightclubs and bars.
Sigard uses a single analysis computer to accept sensor input from several locations. When the software detects a verbally aggressive human voice, the camera at that location is activated, alerting the security guard to a potential problem.
The software imitates the way humans hear sound, splitting sound into different frequencies with varying amounts of energy. Just as a person can immediately detect anger and aggression in the midst of background noise, Sound Intelligence software "listens" for the same parameters that humans use in detecting aggressive speech.
This system is already in place in a few locations in the Netherlands. Police in the UK are also considering installing the system.
