| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this paper, we present a feature enhancement method that uses neural networks (NNs) to map the reverberant feature in a log-melspectral domain to its corresponding anechoic feature. The mapping is done by cascade NNs trained using Cascade2 algorithm with an implementation of segment-based normalization. Experiments using speaker identification (SID) and speech recognition (ASR) systems were conducted to evaluate the method. The experiments of SID system was conducted by using real noisy reverberant datasets, while CENSREC-4 evaluation framework was used as the evaluation for the ASR system. Using limited stereo data consisting of simultaneously recorded clean speech and reverberant speech, the proposed method could remarkably improve the performance of both systems. | |
