SpEx: Multi-Scale Time Domain Speaker Extraction Network
Table IX: SDR (dB), SI-SDR(dB) and PESQ in a comparative study of different number of speakers in the mixed speech on WSJ0-2mix-extr and WSJ0-3mix-extr datasets. The duration of the reference speech is random during training. “#speakers” indicates the number of speakers in the mixture. “Dur.” indicates the duration of the reference speech.
['Training', 'Test #speakers', 'Test Dur.', 'SDR', 'SI-SDR', 'PESQ']
This is consistent with the findings in a human’s performance of a subject evaluation where both listening comprehension and auditory attention decrease significantly as the number of simultaneous audio channels increased [stifelman1994cocktail]. It further confirms that the longer duration of the reference speech achieves better performance. Because the longer duration of the reference speech derives better speaker embedding.
