Subjective evaluation of Role-Play Text-to-Speech synthesis quality using Mean Opinion Score (MOS).

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 | Role-Play Text-to-Speech |
| Dataset (including any stated split) | Role-Play TTS Curated Evaluation Set (Subjective) |
| Metric | MOS |
| Unit | SCALAR |
| 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

- [MOS](<https://www.sota2.com/research/sota/role-play-text-to-speech-on-role-play-tts-curated-evaluation-set-subjective.md?metric=MOS>): Higher is better; unit: SCALAR.
