This paper describes STBU 2006 speaker recognition system, whichperformed well in the NIST 2006 speaker recognition evaluation. STBU isconsortium of 4 partners: Spescom DataVoice (South Africa), TNO(Netherlands), BUT (Czech Republic) and University of Stellenbosch(South Africa). The primary system is a combination of three main kindsof systems: (1) GMM, with short-time MFCC or PLP features, (2) GMM-SVM,using GMM mean supervectors as input and (3) MLLR-SVM, using MLLRspeaker adaptation coefficients derived from English LVCSR system. Inthis paper, we describe these sub-systems and present results for eachsystem alone and in combination on the NIST Speaker RecognitionEvaluation (SRE) 2006 development and evaluation data sets.
