Evaluation of speaker similarity performance for voice cloning tasks using the Full-Duplex-Bench dataset, measured by SSIM.

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 | Voice Cloning Speaker Similarity |
| Dataset (including any stated split) | Full-Duplex-Bench |
| Metric | SSIM |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 5 of 5 |
| 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

- [SSIM](<https://www.sota2.com/research/sota/voice-cloning-speaker-similarity-on-full-duplex-bench.md?metric=SSIM>): Higher is better; unit: PERCENT.
