Dysarthria Speech Biomarker Tracked Severity Across 5 Languages

MHD featured image for dysarthria speech biomarkers, phonological subspace collapse, and cross-language severity tracking.

A 2026 medRxiv preprint found that a training-free speech biomarker tracked dysarthria severity across 890 speakers, 10 corpora, and 5 full-pipeline languages, with all 5 consonant d-prime features showing random-effects correlations with clinical severity (rho = −0.50 to −0.56; all p < 2e−4). Research Highlights Speech-severity signal was broad: Muller et al. evaluated 890 speakers …
