在诸如免提电话和语音控制系统的各种语音处理应用中，需要去混响，特别是当应用在中等或高度混响环境中记录的信号时。在本文中，我们比较了一些经典的和最近开发的多麦克风去混响算法，并通过两个性能指标和语音识别系统验证不同的算法设置。据发现，一些经典的解决方案获得了适度的信号增强。另一方面，更先进的基于子空间的去混响技术，尽管它们的高计算负载，却不能增强信号。
Dereverberation is required in various speech processing applications such as handsfree telephony and voice-controlled systems, especially when signals are applied that are recorded in a moderately or highly reverberant environment. In this paper, we compare a number of classical and more recently developed multimicrophone dereverberation algorithms, and validate the different algorithmic settings by means of two performance indices and a speech recognition system. It is found that some of the classical solutions obtain a moderate signal enhancement. More advanced subspace-based dereverberation techniques, on the other hand, fail to enhance the signals despite their high-computational load.
