In this
paper, we present a principled SVM based speaker verification system. A general
approach to compute two sequences of frames is developed that enables the use
of any kernel at the frame level. An extension of this approach using the Max
operator is then proposed. The new system is compared to state-of-the-art GMM
and other SVM based systems found in the literature on the Polyvar database.
The new system outperforms, most of the time, the other systems, statistically
significantly.
