| Abstract(in English) | This paper introduces example-based speech enhancement, which is a promising single-channel approach to cope with highly nonstationary noise. First, the basic framework of the example-based speech enhancement is outlined. Next, the example search, which is a main process of the approach, is explained and its problems, i.e. the speed and accuracy, are described. Then, we propose solutions to these problems, i.e. an acceleration method using a structured example model and an accuracy improvement method using Deep Neural Network (DNN)-based bottleneck features. We confirm the effectiveness of the proposed methods experimentally. |
