This paper introduces the system fusion of Thu-EE for the NIST 2012 Speaker Recognition Evaluation (SRE12). In our approach, mean Z-norm, pseudo post probability T-norm and bi-criterion optimization are used. These methods mainly concern the changes of evaluation rules and limitation of our development data, which are the new problems for SRE12. Through post evaluation of SRE12 core test, the effectiveness of our approach is validated.
