The mapping function of spectral vectors of the source and target speakers is calculated by the Canonical Correlation Analysis (CCA) estimation based on Gaussian mixture models. Since the spectral envelope feature remains a majority of second order statistical information contained in speech after Linear Prediction Coding (LPC) analysis, the CCA method is more suitable for spectral conversion than Minimum Mean Square Error (MMSE) because CCA explicitly considers the variance of each component of the spectral vectors during conversion procedure. Both objective evaluations and subjective listening tests are conducted. The experimental results demonstrate that the proposed scheme can achieve better per- formance than the previous method which uses MMSE estimation criterion.展开更多

The measure reflecting live process of national musical art is a performing practice. Makom is the most example of Uzbek classical musical heritage. The art of singing plays considerable role in culture of Uzbek national music. On the basis of classical singing the following singing directions as ＂Folk singing＂ （yallachilik）, ＂Classical singing＂ （mumtoz yallachilik）, ＂Grand Song＂ （katta ashulachilik） and ＂Art of Makom＂ singing forms were formulated and developed. Greatest representatives of Margilan School of singing.展开更多
