Evaluation of Partially Fake Speech Localization performance using the Half-Truth (HT) dataset, reporting Equal Error Rate (EER).

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 | Partially Fake Speech Localization |
| Dataset (including any stated split) | Half-Truth (HT) |
| Metric | EER |
| Unit | PERCENT |
| Direction | Lower is better |
| Results loaded | 8 of 8 |
| 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/partially-fake-speech-localization-on-half-truth-ht.md?metric=EER>): Lower is better; unit: PERCENT.
