Originální abstrakt

In this work we revisit discriminative training of the i-vector extractorcomponent in the standard speaker verification (SV) system. Themotivation of our research lies in the robustness and stability of thislarge generative model, which we want to preserve, and focus itspower towards any intended SV task. We show that after generativeinitialization of the i-vector extractor, we can further refine itwith discriminative training and obtain i-vectors that lead to betterperformance on various benchmarks representing different acousticdomains.
