by GLOOM

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 …

Parkinson’s Speech Pauses Track Sentence Complexity and MoCA Scores

by GLOOM

MHD featured image for Parkinson's speech pauses, sentence complexity, MoCA scores, and dysarthria.

A 2026 connected-speech study found that people with Parkinson’s disease produced more silent pauses than older controls while reading aloud: 2.185 vs. 1.595 mean pauses, while long sentences produced 2.676 pauses vs. 1.033 in short sentences.1 Within the Parkinson’s group, MoCA scores correlated with total pause count (rs = −0.502, p = 0.005). Research Highlights …
