# Speech Naturalness Assessment on CVSS-C Source: [Speech Naturalness Assessment on CVSS-C]() Collection index: [llms.txt]() Data updated: 2026-02-26T06:07:51.668Z Evaluation of speech naturalness using the UTMOS metric on the CVSS-C dataset. 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 Naturalness Assessment | | Dataset (including any stated split) | CVSS-C | | Metric | UTMOS Score | | Unit | SCALAR | | 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 - [UTMOS Score](): Higher is better; unit: SCALAR. ## Recorded results | Method | UTMOS Score | Result date | Report paper | | --- | --- | --- | --- | | Vanilla | 3.74 | Not recorded | 6976f4e6a2b28e761d87c0c7 | | Vanilla | 3.72 | Not recorded | 6976f4e6a2b28e761d87c0c7 | | Vanilla | 3.71 | Not recorded | 6976f4e6a2b28e761d87c0c7 | | Chain of Modality | 3.7 | Not recorded | 6976f4e6a2b28e761d87c0c7 | | Chain of Modality | 3.68 | Not recorded | 6976f4e6a2b28e761d87c0c7 | | Tri-Task Learning | 3.68 | Not recorded | 6976f4e6a2b28e761d87c0c7 | | Chain of Modality | 3.66 | Not recorded | 6976f4e6a2b28e761d87c0c7 | | Tri-Task Learning | 3.66 | Not recorded | 6976f4e6a2b28e761d87c0c7 | | Tri-Task Learning | 3.65 | Not recorded | 6976f4e6a2b28e761d87c0c7 | | S2T+TTS | 3.04 | Not recorded | 6976f4e6a2b28e761d87c0c7 | ### Vanilla UTMOS Score: 3.74.
