Abstract: This paper briefly describes the dot-scoring speaker recognition system developed by the Software Technology Working Group (http://gtts.ehu.es) at the University of the Basque Country (EHU), for the NIST 2010 Speaker Recognition Evaluation. The system does eigenchannel compensation in the sufficient statistics space and scoring is performed by a simple dot product. An optimized Matlab implementation of of the eigenchannels estimation, the channel compensation and the normalized mean vector computation is provided.
