# Speech-to-Speech Translation (en2fra) on CVSS-C Source: [Speech-to-Speech Translation (en2fra) on CVSS-C]() Collection index: [llms.txt]() Data updated: 2026-02-26T05:37:01.843Z Evaluation of Speech-to-Speech Translation performance for the English-to-French direction on the CVSS-C dataset, reporting BLEU scores. 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-to-Speech Translation (en2fra) | | Dataset (including any stated split) | CVSS-C | | 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](): Higher is better; unit: PERCENT. ## Recorded results | Method | BLEU | Result date | Report paper | | --- | --- | --- | --- | | S2T+TTS | 28.27 | Not recorded | 6976f4e6a2b28e761d87c0c7 | | Chain of Modality | 25.12 | Not recorded | 6976f4e6a2b28e761d87c0c7 | | Chain of Modality | 25.04 | Not recorded | 6976f4e6a2b28e761d87c0c7 | | Chain of Modality | 24.2 | Not recorded | 6976f4e6a2b28e761d87c0c7 | | Tri-Task Learning | 20.96 | Not recorded | 6976f4e6a2b28e761d87c0c7 | | Tri-Task Learning | 20.71 | Not recorded | 6976f4e6a2b28e761d87c0c7 | | Vanilla | 19.33 | Not recorded | 6976f4e6a2b28e761d87c0c7 | | Tri-Task Learning | 18.68 | Not recorded | 6976f4e6a2b28e761d87c0c7 | | Vanilla | 17.93 | Not recorded | 6976f4e6a2b28e761d87c0c7 | | Vanilla | 14.65 | Not recorded | 6976f4e6a2b28e761d87c0c7 | ### S2T+TTS BLEU: 28.27.
