Abstract
Voice activity detection (VAD) algorithms have becomean integral part of many of the recently standardizedwireless cellular and Personal CommunicationsSystems (PCS). In this paper, we present a comparativestudy of the performance of three recently proposedVAD algorithms under various acoustical backgroundnoise conditions. We also propose new ideas toenhance the performance of a VAD algorithm in wirelessPCS speech applications.1. INTRODUCTIONConversational speech is a sequence of...Keywords
