ATVS submission to ALBAYZIN-VL08 will consist of different combinations of a set of acoustic and phonotactic subsystems that our group has developed during the last years. Most of these subsystems have already been evaluated on NIST LRE 07 evaluation. At the time of writing this system description some of the details of our submission are still undefined. Therefore we will briefly describe our systems and the intended combinations to be submitted, but these settings should not be taken as final in any way. As acoustic subsystems we will use a GMM SuperVectors and a GLDS-SVM subsystem, while the phonotactic subsystem will be a PhoneSVM system. We are still deciding the best fusion strategy and the best combination of subsystems at the time of writing. Output scores will be submitted in the form of log-likelihood ratio (logLR) scores in an application independent way. Open-set detection thresholds will be set to the Bayes thresholds in all cases, and the same logLR sets will probably be submitted to the closed- and open-set conditions. 1.
