...The result of the BUT fused system (row 11) was obtained by fusing phonotactic and acoustic systems [108], where the phonotactic system is very similar to our system (same phone recognizers) except they used phone lattice and antimodel technique....

...Following [Matejka et al., 2006], they further discriminatively train the dialect GMMs with the Maximum Mutual Information (MMI) criterion, where the objective function is the posterior probability of correctly classifying all training utterances, using the extended Baum-Welch algorithm [Povey, 2004]....

...We use these posterior probabilities to represent the detection scores used in plotting DET curves, similar to [Matejka et al., 2006]; where D is the set of dialects of interest, p(Or|λDx) represents the likelihood of Or given the model λDx of dialect Dx, and τr normalizes duration differences across trials....
