Evaluation of Speech-to-Speech Translation performance on the LRS3-T Es-En subset, measured using metrics like BLEU and 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 | Speech(A)-To-Speech(AV) Translation |
| Dataset (including any stated split) | LRS3-T Es-En |
| Metric | BLEU |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 10 of 10 |
| 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

- [BLEU](<https://www.sota2.com/research/sota/speech-to-speech-translation-on-lrs3-t-es-en.md?metric=BLEU>): Higher is better; unit: PERCENT.

- [MOS](<https://www.sota2.com/research/sota/speech-to-speech-translation-on-lrs3-t-es-en.md?metric=MOS>): Higher is better; unit: SCALAR.
