This paper illustrates speech enhancement techniques for multi-speaker distant-talk speech recognition, where a conversation scene analysis is adopted as a test scenario. Our speech enhancement techniques include dereverberation, speech separation, and noise suppression. Because some of our techniques employ both the spatial information of speech sources and the speech spectrum information, their output signals become suitable for the input of a speech recognizer. We report the latest speech enhancement techniques and their speech recognition performance in a real conversation. Moreover, the effect of deep learning in multi-speaker speech recognition is also discussed. |
