چکیده
This paper briefly describes the language recognition system developed by the Sofware Technology Working Group (http://gtts.ehu.es) at the University of the Basque Country in collaboration with IKERLAN Technological Research Center, and submitted to the NIST 2009 Language Recognition Evaluation. The system consists of a hierarchical fusion of individual subsystems: two acoustic GLDS-SVM systems using 19 MFCC and 7-2-3-7 SDC-MFCC, two acoustic GMM-SVM systems using 19 MFCC and 7-2-3-7 SDC-MFCC, and eleven Phone-SVM systems based in 10 phonetic decoders plus a decoderpairs phoneme co-occurrence system. Application independent well-calibrated log-likelihood-ratio scores and Bayes thresholds are used for decision making.1
