This paper presents BUT system submitted to NIST 2008 SRE. It includes two subsystems based on Joint Factor Analysis (JFA) GMM/UBM and one based on SVM-GMM. The systems were developed on NIST SRE 2006 data, and the results are presented on NIST SRE 2008 evaluation data. We concentrate on the influence of side information in the calibration.
