Evaluation of Speech Enhancement performance on the CHiME-3 dataset, measured using objective quality metrics including PESQ, eSTOI, ovrl, sig, and bak.

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) | CHiME-3 |
| Metric | PESQ |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 4 of 4 |
| 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-chime-3.md?metric=PESQ>): Higher is better; unit: SCALAR.

- [eSTOI](<https://www.sota2.com/research/sota/speech-enhancement-on-chime-3.md?metric=eSTOI>): Higher is better; unit: SCALAR.

- [Overall Quality (ovrl)](<https://www.sota2.com/research/sota/speech-enhancement-on-chime-3.md?metric=Overall%20Quality%20(ovrl)>): Higher is better; unit: SCALAR.

- [Signal Quality (sig)](<https://www.sota2.com/research/sota/speech-enhancement-on-chime-3.md?metric=Signal%20Quality%20(sig)>): Higher is better; unit: SCALAR.

- [Background Quality (bak)](<https://www.sota2.com/research/sota/speech-enhancement-on-chime-3.md?metric=Background%20Quality%20(bak)>): Higher is better; unit: SCALAR.
