While considerable work has been done to characterize the detrimental effects of channel variability on automatic speaker verification (ASV) performance, little attention has been paid to the effects of room reverberation. This paper investigates the effects of room acoustics on the performance of two far-field ASV systems: GMM-UBM (Gaussian mixture model(More)
It is known that channel variability compromises automatic speaker recognition accuracy. However, little attention has been given so far to the detrimental effects encountered under reverberant environments. In this paper, we focus on the issue of automatic speaker verification (ASV) under several levels of room reverberation. Alternative auditory inspired(More)
