Multiple Sound Source Localization Based on Stochastic Modeling of Spatial Gradient Spectra Autor Ueno, Natsuki, Kameoka, Hirokazu

“… Two source localization methods are proposed: one is the expectation-minimization algorithm for a given number of sources, and the other is the variational Bayesian inference for an unknown number of sources. By numerical experiments, the localization accuracies of the two proposed methods are compared with the baseline method…”

An integrated speech-background model for robust speaker identification Autor Reynolds, D.A., Rose, R.C.

“…-minimization algorithm. Using this formalism, speaker model parameters are estimated in the presence of the background process, and a scoring procedure is implemented for computing the speaker likelihood in the noise corrupted environment. The performance was evaluated using a 16-speaker conversational speech database with both speech babble and white noise background processes.< >…”
