New Background Modeling for Speaker Verification

Dat Tran

University of Canberra, Australia

A new background speaker modelling method is presented in this paper for text-independent speaker verification using Gaussian mixture models. This method does not require speech databases of other speakers to build background speaker models. A background model can be built directly from the same claimed speaker's database and has a smaller number of Gaussian mixtures compared to the claimed speaker model. Experiments performed on the YOHO database showed a better result for speaker verification using the 64- mixture claimed speaker model and 16-mixture background model compared to current background model set methods using five closest background models.
