Description and analysis of the Brno276 system for LRE2011
This paper contains a description of data, systems and fusions developed by the joint team of Brno University of Technol- ogy (BUT), Politecnico di Torino (PoliTo) and AGNITIO for the NIST 2011 Language Recognition Evaluation. The primary submission was a fusion of one acoustic and three phonotactic systems, with extensive use of sub-space projections for both approaches. The results are analysed from the view-point of the new NIST measure involving the N = 24 worst language pairs. Some of the results are compared to the MIT-LL submission. As in our previous work, we conclude that having lots of carefully processed data is as important as having good algorithms.
