Voice activity detection (VAD) is a vital process in voice communication systems to avoid unnecessary coding and transmission of noise. Most of the existing VAD algorithms continue to suffer high false alarm rates and low sensitivity when the signal-

Real-time Voice Activity Detector Using Gammatone Filter and Modified Long-Term Signal Variability

Autor: Cheah Heng Tan, L Vengadasalam, Thean Hai Ooi, Wei Qing Ong, Alan W. C. Tan

Publikováno v: Proceedings of the International Conference on Imaging, Signal Processing and Communication.

In this paper, a real-time robust voice activity detector (VAD) is proposed. The proposed VAD adopts the gammatone filter and modify the existing long-term signal variability (LTSV) measure, i.e. known as GMLTSV in short. The proposed VAD is an impro
