Speech Activity Detection (SAD) is an essential component for a variety of speech processing applications. It has been observed that performances of various speech based tasks are very much dependent on the efficiency of the SAD. In this paper, the authors have systematically reviewed some popular SAD techniques and their applications in speaker recognition. Speaker verification system using different SAD technique is experimentally evaluated on NIST speech corpora using Gaussian Mixture Model-Universal Background Model (GMM-UBM) based classifier for clean and noisy conditions. It has been found that two Gaussian modeling based SAD is comparatively better than other SAD techniques for different types of noises.
