| Abstract(in English) | We proposed RSF and DRA as the noise robust methods. The RSF is a technique for applying the filter to the spectrum twice. This technique has the feature of speech enhancement, reduction of convolutive noise and a part of additive noise. However, the RSF method removes a part of the speech. Therefore, the recognition rates are deteriorated in clean environment. We propose the RSF based on the estimated SNR. The estimated SNR calculate each frame and frequency. As a result of the isolated word recognition experiments, the recognition rates are improved in high SNR and clean environments. |
