In a distant-talking environment, reverberation drastically degrades speech recognition performance. In previous work, we proposed a blind dereverberation method based on power spectral subtraction (SS) using a multi-channel least mean square (LMS) algorithm. Instead of power SS, we proposed a dereverberation method based on generalized SS and evaluated it by a large-vocabulary continuous speech recognition task. In this paper, we evaluate our proposed method in simulated and real noisy reverberant environments and show that our proposed method is effective in a real noisy reverberant environment. |
