University of the Basque Country + Ikerlan System for NIST 2008 Speaker Recognition Evaluation

This paper describes the speaker recognition system EHUIKER developed in the GTTS group of the University of the Basque Country in collaboration with IKERLAN Technological Research Center. The EHUIKER system submitted to the NIST 2008 Speaker Recognition Evaluationis is based on the standard Universal Background ModelGaussian Mixture Modeling (UBM-GMM) approach. In order to compensate for environment and/or channel mismatch, noise reduction and channel compensation techniques are applied to speech signals. 1
