AP18-OLR Challenge: Three Tasks and Their Baselines
Table 2: Cavg and EER results on 1 second and full-length conditions

Short-utterance LID The first task identifies short-duration utterances. AP17-OLR-test contains three subset sets with different durations (1 second, 3 second and regular length). Besides the performance of the baseline systems on the 1 second condition, we also report the performance on the regular length for reference. From the results, we find that short-duration utterances are hard to recognize for both the i-vector system and the DNN systems, while DNN systems show more robustness.
