Evaluation of Speaker Diarization performance on the CALLHOME corpus subset characterized by an 11.8% overlap ratio, typically measured using Diarization Error Rate (DER).

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 | Speaker Diarization |
| Dataset (including any stated split) | CALLHOME overlap ratio 11.8% |
| Metric | DER |
| 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

- [DER](<https://www.sota2.com/research/sota/speaker-diarization-on-callhome-overlap-ratio-11-8-percent.md?metric=DER>): Lower is better; unit: PERCENT.
