Table 2: Most recurrent features among the top 50 sets, summed for all 56 speakers. Occ. is the number of occurrences over the 50 main speakers. identified. Similarly, specificity or \"class 2 recall\" details how many samples of the validation set belonging to the all class were correctly identified using the following formulas:
