| Abstract(in English) | We previously proposed a Mel-Wiener filter to enhance Mel-LPC spectra in presence of additive noise. The proposed filter was estimated based on minimization of sum of the square error on the linear frequency scale and then efficiently implemented in the autocorrelation domain without denoising input speech. In this paper the autoregressive (AR) model of noise is used to detect noise. The performance of the filter is evaluated on AURORA-2J (CENSREC-I) database. With the proposed Wiener filter the word accuracy is improved by about 58% relative to the baseline. |
