Abstract :
In this paper, we propose a novel and practical single channel dereverberation scheme, which utilizes surround retinex model in frequency domain. A dereverberation filter is derived by the proposed method for suppressing the environmental reflections. The proposed algorithm can achieve effective dereverberation with a more reasonable computational complexity than conventional methods. Experimental results also reveal an improvement in automatic speech recognition (ASR) performance even in severely reverberation environments.
