In speech production, epochs are glottal closure instants where significant energy is released from the lungs. Extracting an epoch accurately is important in speech synthesis, analysis, and pitch oriented studies. The time-varying characteristics of the source and the system, and channel attenuation…
We develop an unbiased estimate of mean-squared error (MSE), where the observations are assumed to be drawn from a Gaussian mixture (GM) distribution. Stein's unbiased risk estimate (SURE) is an unbiased estimate of the MSE, and was originally proposed for independent and identically distributed (i.…
We address the problem of extending the bandwidth of speech signals, which is of importance to enhance the quality and intelligibility of the telephone speech. The low-pass filtering effect of the telephone communication channels eliminate the high-frequency components of the speech signal, and it i…
