- W2344781296 abstract "Voice Activity Detection (VAD) Systems have various standards. One of the famous and practical standards is ITU- U G.729B. In G.729B, VAD decision, compare with other standards and new methods, has poor performance for voice frames especially in low Signal-to-Noise Ratios (SNRs). However, since this standard has good properties that we try to modify its low performance in adverse environments. One point that we focus on this standard is trying to have minimum changes. Therefore we use some new methods without major modification on basic structure. In this methodology we use some parameters in the first part and connect it to the main block. We compare the proposed method, using objective parameters, with basic version of G.729B standard and ETSI AMR option 1 and 2. This comparison study in various types of noises like Gaussian, Vehicle and Babble noise." @default.
