Abstrakt

We have introduced a novel approach for language recognition.Three classifiers (linear generative model, SVM and logistic regression)have been tested in the iVector space, and all outperformthe state-of-the-art JFA system. Very simple and fast classifierbased on linear generative model provides excellent performanceover all conditions. The advantage of this classifieris also its scalability: addition of a new language only requiresestimating the mean over the corresponding iVectors. Most ofthe computational load is in the iVector generation. Hence, as anext step, we will try to obtain iVectors from the utterances andthe corresponding sufficient statistics in a more direct way.
