    CarLab 2025 is a novel data-driven classification framework that improves voice disorder classification by aligning with acoustic relationships.

  • 2

    CarLab 2025 achieved a balanced accuracy of 67.20%, surpassing the best-performing clinical framework's accuracy of 61.03%.

  • 3

    Models trained with structured taxonomies outperformed those with narrow, single-disorder labels in out-of-domain generalisation.

  • 4

    Multi-task learning did not provide advantages over single-task training, while targeted data injection improved binary detection accuracy.

  • 5

    Robust multi-class generalisation requires diverse multi-source training data, highlighting the need for varied recording conditions.
