BUT system description: NIST SRE 2008

BUT submitted three systems to NIST SRE 2008 evaluations, only to the short2-short3 condition. The primary system is a fusion of three sub-systems: 2 based on MFCC and factor analysis and one making use of SVM scoring of CMLLR and MLLR matrices of an ASR system. The first contrastive systems differs only in callibration and the second contrastive system is a simplified version of the primary one (no ASR use).
