Originální abstrakt

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