Evaluation of Speech Enhancement performance on the test split of the LRS2 dataset augmented with VGGSound noises, measured using metrics like PESQ, CSIG, CBAK, COVL, and STOI.

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 Enhancement |
| Dataset (including any stated split) | LRS2 mixed with VGGSound noises (test) |
| Metric | PESQ |
| 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

- [PESQ](<https://www.sota2.com/research/sota/speech-enhancement-on-lrs2-mixed-with-vggsound-noises-test.md?metric=PESQ>): Higher is better; unit: SCALAR.

- [CSIG](<https://www.sota2.com/research/sota/speech-enhancement-on-lrs2-mixed-with-vggsound-noises-test.md?metric=CSIG>): Higher is better; unit: SCALAR.

- [CBAK](<https://www.sota2.com/research/sota/speech-enhancement-on-lrs2-mixed-with-vggsound-noises-test.md?metric=CBAK>): Higher is better; unit: SCALAR.

- [COVL](<https://www.sota2.com/research/sota/speech-enhancement-on-lrs2-mixed-with-vggsound-noises-test.md?metric=COVL>): Higher is better; unit: SCALAR.

- [STOI](<https://www.sota2.com/research/sota/speech-enhancement-on-lrs2-mixed-with-vggsound-noises-test.md?metric=STOI>): Higher is better; unit: SCALAR.
