# Speech Separation on WHAM! 2-speaker (test) Source: [Speech Separation on WHAM! 2-speaker (test)]() Collection index: [llms.txt]() Data updated: 2026-03-05T08:24:12.648Z Evaluation of Speech Separation performance on the test split of the WHAM! 2-speaker dataset, measured using metrics like SI-SNRi and SDRi. A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage. | Scope | Recorded value | | --- | --- | | Task | Speech separation | | Dataset (including any stated split) | WHAM! 2-speaker (test) | | Metric | SI-SNRi | | Unit | SCALAR | | Direction | Higher is better | | Results loaded | 18 of 18 | | Coverage | All results currently returned for this benchmark | Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol. ## Metrics - [SI-SNRi](): Higher is better; unit: SCALAR. - [SDRi](): Higher is better; unit: SCALAR. ## Recorded results | Method | SI-SNRi | Result date | Report paper | | --- | --- | --- | --- | | SepReformer (L) + DM | 18.4 | Not recorded | 68fa7a1c1e209131cea813fc | | MossFormer2 + DM | 18.1 | Not recorded | 68fa7a1c1e209131cea813fc | | SepReformer (M) | 17.8 | Not recorded | 68fa7a1c1e209131cea813fc | | PRESS-12 @ 12 (M) + FT | 17.49 | Not recorded | 68fa7a1c1e209131cea813fc | | MossFormer (L) + DM | 17.3 | Not recorded | 68fa7a1c1e209131cea813fc | | SepReformer (S) | 17.3 | Not recorded | 68fa7a1c1e209131cea813fc | | PRESS-4 @ 4 (S) + FT | 17.25 | Not recorded | 68fa7a1c1e209131cea813fc | | PRESS-12 @ 8 (M) + FT | 17.21 | Not recorded | 68fa7a1c1e209131cea813fc | | SepReformer (T) | 17.2 | Not recorded | 68fa7a1c1e209131cea813fc | | PRESS-12 @ 12 (M) | 16.65 | Not recorded | 68fa7a1c1e209131cea813fc | | PRESS-12 @ 8 (M) | 16.57 | Not recorded | 68fa7a1c1e209131cea813fc | | PRESS-4 @ 4 (S) | 16.49 | Not recorded | 68fa7a1c1e209131cea813fc | | PRESS-12 @ 4 (M) + FT | 16.47 | Not recorded | 68fa7a1c1e209131cea813fc | | PRESS-12 @ 4 (M) | 16.43 | Not recorded | 68fa7a1c1e209131cea813fc | | SepFormer + DM | 16.4 | Not recorded | 68fa7a1c1e209131cea813fc | | SepFormer | 14.7 | Not recorded | 68fa7a1c1e209131cea813fc | | DualPathRNN | 13.7 | Not recorded | 68fa7a1c1e209131cea813fc | | Conv-TasNet | 12.7 | Not recorded | 68fa7a1c1e209131cea813fc | ### SepReformer (L) + DM SI-SNRi: 18.4.
