Jordi Luque,

L2F and TALP


In this talk, we are going to show results concerning the work we have performed last months at the L2F Laboratory. The talk will complement previous presentations showing speaker verification results reported on a subset of the NIST SRE 2008 evaluation. Such experiments are the core of the development of the Speaker Verification system will be submit to the incoming NIST SRE 2010 evaluation.

The performance of several systems, previously explained, will be compared. Among them: The classical GMM-UBM approach, the Gaussian Super Vectors technique, a GMM-UBM provided with the Joint Factor Analysis compensation technique and a newly developed system based on a Speaker Dependent Transformation Network applied to a phone classifier based on MLP. In addition, some clues about score normalization techniques will be presented.
