Abstract :
We have been investigating a speech processing system for ensuring safety and security, namely, acoustic-based security system. Focusing on indoor security, we have been studying for an advanced security system which can discriminate emergency shout from the other acoustic sound events based on automatic understanding of speech events.In this paper, we present our investigations, and describe fundamental results.
