Training-Free Cross-Lingual Dysarthria Severity Assessment via Phonological Subspace Analysis in Self-Supervised Speech Representations

Researchers have developed a training-free method to assess dysarthria severity using phonological subspace analysis in self-supervised speech representations, enabling scalable cross-lingual evaluation without requiring labeled pathological data. This technique measures degradation in phonological features from healthy control speech, providing significant correlations with clinical severity across multiple languages and conditions, thus offering a valuable tool for clinicians and researchers lacking specialized training datasets.
