Description

Implementation details of (i)-(iii) can be found in [1].

The fourth function (gmm2sv.m) is to concatenate the means (i.e. centers) of GMM. The concatenated mean of adapted GMM is known as GMM supervector (GSV) and it is used in GMM-SVM based speaker recognition system. Details of GMM-SVM based speaker recognition system can be found in [2].

These codes require Netlab toolbox.
