Augmenting Dysarthric Speech Severity Assessment with MOS Supervision

arXiv:2606.18645v1 Announce Type: cross Abstract: Dysarthria is a speech disorder marked by reduced intelligibility and communicative effectiveness. Automatic utterance-level assessment of dysarthric speech can support scalable speech monitoring and therapy-related analysis. Yet training such systems is bottlenecked by the scarcity of clinically annotated dysarthric speech. This work proposes to augment dysarthric speech assessment using data from speech synthesis evaluations, specifically human-annotated utterances with Mean Opinion Score (MOS) labels from the QualiSpeech corpus. Experiments

Why this matters
Why now

The scarcity of annotated clinical speech data is driving innovation in AI training methods, leveraging existing resources like speech synthesis evaluations.

Why it’s important

This development could democratize access to advanced speech assessment tools for dysarthria, improving patient monitoring and therapy outcomes through scalable AI.

What changes

AI systems for dysarthric speech assessment can now be more effectively trained and deployed, potentially reducing reliance on extensive clinical annotations.
