| Abstract(in English) | In this paper, we show some properties of iterative Wiener filter for speech enhancement with SNR (Signal-to-Noise Ratio) changed by increasing the number of iterations. The iterative spectrum subtraction, which is one of the typical techniques of speech enhancement, is used for comparison. Additionally, we make a comparison in the case of changing the estimation method of the power spectrum, and in the case of using different iterative methods in iterative Wiener filter. We evaluated the accuracy in SNR for each iteration. It was found that the iterative Wiener filter provides the best performance at an early stage of the iterations. This means that it is not necessary to continue to increase the number of iterations. On the other hand, it was found that in order to obtain a high SNR in the iterative spectral subtraction method, it is necessary to continue to increase the number of iterations compared with the iterative Wiener filter. However, it is difficult to determine the appropriate number of iterations. We showed theoretically the difference obtaind in SNR for iterative Wiener filter and iterative spectral subtraction method. |
