Abstract

This work studies the usage of the (currently state-of-the-art) Deep Neural Networks (DNN) i-vector/PLDA-based speaker recognition systems in multi-language (especially non-English) conditions. On the ``Language Pack'' of the PRISM set, we evaluate the systems' performance using NIST's standard metrics. We study the use of multi-lingual DNN in place of the original English DNN on these multi-language conditions. We show that not only the gain from using DNNs vanishes, but also the DNN-based systems tend to produce de-calibrated scores under the studied conditions. This work gives suggestions for directions of future research rather than any particular solutions.
