BACKGROUND The present invention relates generally to signal process ing. More
particularly, it relates to techniques for Suppressing noise in a speech signal, which may be …

We discuss techniques for voice activity detection (VAD) for voice over Internet Protocol
(VoIP). VAD aids in saving the bandwidth requirement of a voice session, thereby increasing …

This paper presents an alternative energy-based algorithm to provide speech/silence
classification. The algorithm is capable to track non-stationary signals and dynamically …

Spectral subtraction is a method for restoration of the power or the magnitude spectrum of a
signal observed in additive noise, through subtraction of an estimate of the average noise …

This paper introduces a new approach for electromyography (EMG) activity monitoring
based on an improved version of the adaptive linear energy detector (ALED), a widely used …

In this study, a voice activity detection technique is designed using features such as short-
term energy, periodicity and spectral flatness. The desired results are obtained by using …

This paper describes a new approach for detecting onset/offset electromyography activity.
The proposed approach is based on energy analysis which has been widely used in Voice …

Voice enabled applications over the Internet are rapidly gaining popularity. Reducing the
total bandwidth requirement can make a non-trivial difference for the subscribers having low …
