This letter presents a new voice activity detection (VAD) method using a uniformly most powerful (UMP) test to improve the performance of Sohn's et al.'s VAD. The UMP test is employed to derive a redefined decision rule based on the likelihood ratio test (LRT). The proposed method provides the decision rule by comparing the magnitude of the noisy speech(More)
This paper presents a new voice activity detection (VAD) method using the Gaussian distribution and a uniformly most powerful (UMP) test. The UMP test is employed to derive the new decision rule based on likelihood ratio test (LRT). This method requires the Rayleigh distribution for the magnitude of the noisy spectral component and the adaptive threshold(More)
