Evaluation of Lipreading performance on the GRID dataset, specifically focusing on the subset involving overlapped speakers, measured using Character Error Rate (CER) and Word Error Rate (WER).

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 | Lipreading |
| Dataset (including any stated split) | GRID (overlapped speakers) |
| Metric | CER |
| Unit | PERCENT |
| Direction | Lower 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

- [CER](<https://www.sota2.com/research/sota/lipreading-on-grid-overlapped-speakers.md?metric=CER>): Lower is better; unit: PERCENT.

- [WER](<https://www.sota2.com/research/sota/lipreading-on-grid-overlapped-speakers.md?metric=WER>): Lower is better; unit: PERCENT.
