In this paper we propose a sub-band energy based end-ofutterance algorithm that is capable of detecting the time instant when the user has stopped speaking. The proposed algorithm finds the time instant at which many enough sub-band spectral energy trajectories fall and stay for a pre-defined fixed time below adaptive thresholds, i.e. a non-speech period is detected after the end of the utterance. With the proposed algorithm a practical speech recognition system can give timely feedback for thedoi:10.1109/icassp.2001.940814 dblp:conf/icassp/HariharanHL01 fatcat:3qwzekdrdfdh7e4fuepp6i2wly
