Evaluation of Speech Enhancement performance on the development split of the CHiME-3 simulated challenge dataset, typically measured using metrics such as SDR and PESQ.

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 sim (dev) |
| Metric | SDR |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 3 of 3 |
| 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

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

- [ΔPESQ](<https://www.sota2.com/research/sota/speech-enhancement-on-chime-3-sim-dev.md?metric=%CE%94PESQ>): Higher is better; unit: SCALAR.
