Comparison of voice activity detection algorithms for wireless personal communications systems
Khaled El-Maleh, P. Kabal · 2002
Voice activity detection (VAD) algorithms have become an integral part of many of the standardized wireless cellular and personal communications systems (PCS). We present a comparative study of the performance of three proposed VAD algorithms under various acoustical background noise conditions. We also propose new ideas to enhance the performance of a VAD algorithm in wireless PCS speech applications.
