Evaluation of Multilingual Speech Synthesis performance on the test split of the MiniMax-MLS dataset, measured using Naturalness Mean Opinion Score (N-MOS) and Speech Mean Opinion Score (S-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 | Multilingual Speech Synthesis |
| Dataset (including any stated split) | MiniMax-MLS (test) |
| Metric | N-MOS |
| Unit | SCALAR |
| Direction | Higher 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

- [N-MOS](<https://www.sota2.com/research/sota/multilingual-speech-synthesis-on-minimax-mls-test.md?metric=N-MOS>): Higher is better; unit: SCALAR.

- [S-MOS](<https://www.sota2.com/research/sota/multilingual-speech-synthesis-on-minimax-mls-test.md?metric=S-MOS>): Higher is better; unit: SCALAR.
