Evaluation of models assessing the naturalness of dysarthric speech using the SAP (Speech Accessibility Project) dataset, measured by Mean Squared Error (MSE), Linear Correlation Coefficient (LCC), and Spearman's Rank Correlation Coefficient (SRCC).

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 | Dysarthric Speech Naturalness Assessment |
| Dataset (including any stated split) | SAP (Speech Accessibility Project) |
| Metric | MSE |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 25 of 25 |
| 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

- [MSE](<https://www.sota2.com/research/sota/dysarthric-speech-naturalness-assessment-on-sap-speech-accessibility-project.md?metric=MSE>): Lower is better; unit: SCALAR.

- [LCC](<https://www.sota2.com/research/sota/dysarthric-speech-naturalness-assessment-on-sap-speech-accessibility-project.md?metric=LCC>): Higher is better; unit: SCALAR.

- [SRCC](<https://www.sota2.com/research/sota/dysarthric-speech-naturalness-assessment-on-sap-speech-accessibility-project.md?metric=SRCC>): Higher is better; unit: SCALAR.
