Robust Endpoint Detection

Part of the Signals and Communication Technology book series (SCT)

Abstract

Often the first step in speech signal processing is the use of endpoint detection to separate speech and silence signals for further processing. This topic has been studied for several decades; however, as wireless communications and VoIP phones are becoming more and more popular, more background and system noises are affecting communication channels, which poses a challenge to the existing algorithms; therefore new and robust algorithms are needed.
