Regularized Within-Class Precision Matrix Based PLDA in Text-Dependent Speaker Verification
In the field of speaker verification, probabilistic linear discriminant analysis (PLDA) is the dominant method for back-end scoring. To estimate the PLDA model, the between-class covariance and within-class precision matrices must be estimated from samples. However, the empirical covariance/precisio...
