Voice Activity Detector is a branch of signal processing science and is one of the most important areas of audio signal processors that are used in many telecommunication and audio systems such as speech recognition, speech compression, noise estimation and removal in speech enhancement system, wireless communication systems, and many other communication systems. We combine a number of relatively new methods for speech recognition in this paper. The experiments performed on clean and noisy data (with moderate noise) show that the proposed method reduces the EER error rate to the best of the other methods examined in this paper by about 85.3%.
