Directly Modeling of Correlation Matrices for GMM in Speaker Identification


In this paper, we present a new framework to model full covariance matrices of Gaussian components. In this framework, directly modeling the full correlation matrix instead of the full covariance matrix is our purpose, as the correlation matrix is the direct description of the correlation of inter-feature elements. In order to model full correlation… (More)
