Improving speaker discrimination of target speech extraction with time-domain SpeakerBeam
Table 3: SDR [dB] on the CSJ-2mix corpus.
['(1)', 'Mixture', 'FF 0.19', 'MM 0.18', 'FM 0.18', 'avg 0.18']
These results were obtained when using all 937 training speakers for training the models. TD-SpeakerBeam achieved much better performance than FD-SpeakerBeam and TasNet with or without oracle speaker selection. Moreover, SI-loss provided further consistent performance improvement of up to 1 dB.
