Evaluation of Speech Deepfake Detection performance on the SDD-Eval-50 Challenging dataset, reporting EER and Accuracy.

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 Deepfake Detection |
| Dataset (including any stated split) | SDD-Eval-50 Challenging |
| Metric | EER |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 6 of 6 |
| 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

- [EER](<https://www.sota2.com/research/sota/speech-deepfake-detection-on-sdd-eval-50-challenging.md?metric=EER>): Lower is better; unit: SCALAR.

- [Accuracy](<https://www.sota2.com/research/sota/speech-deepfake-detection-on-sdd-eval-50-challenging.md?metric=Accuracy>): Higher is better; unit: PERCENT.
