作者探索了语音去混响技术，其原理是恢复原始(无回声)语音的包络调制。根据他们以前在用于加性降噪应用的这类处理方面的经验，他们将数据设计的滤波器组技术应用于混响语音。将他们的结果与其他工作相比较，讨论了这种方法的有效性和局限性。
The authors explore speech dereverberation techniques whose principle is the recovery of the envelope modulations of the original (anechoic) speech. Based on their previous experience with such kind of processing for additive noise reduction applications, they apply a data designed filter-bank technique to the reverberant speech. Comparing their results with other works they discuss the effectiveness and limitations of this type of approaches.
