SpEx: Multi-Scale Time Domain Speaker Extraction Network
Table VI: SDR (dB) of extracted speech when we evaluate the same SpEx system on varying duration of reference speech of target speaker at [0, 1)dB, [1, 3)dB, [3, 5]dB.
['MethodsSNR(dB)', '[0, 1)', '[1, 3)', '[3, 5]']
Without surprise, test data of higher SNR performs better than that of lower SNR. We also observe that the proposed SpEx network achieves 52.9%, 39.6% and 30.4% relative SDR improvement over the best baseline system, SBF-MTSAL-Concat, for [0, 1)dB, [1, 3)dB and [3, 5]dB SNR group respectively. Since the SNR of the simulated database is limited from 0dB to 5dB, in the future work, we will investigate various SNR ranges, i.e., from -10dB to 20dB.
