| Abstract(in English) | This paper describes a method for reducing sudden noise using a static and dynamic speech feature model. We have propoesed a method for reducing these noises using static feature model after the noisy frame is detected and what noise overlapped is classfied. But, the previous method has a problem that the noise reduction is not peroformed if the frame is not determined as noisy one although the frame has a noise. In this paper, we propose a noise reduction method using a dynamic feature model and last frame data in order to deal with such noisy frames. In our experiments, the proposed method achieved better performance for recognition of utterances overlapped by sudden noises than the previous method. |
