Improving Voice Recognition for People with Speech Disabilities

A new study shows that automatic speech recognition (ASR) systems trained on speech from people with Parkinson’s disease are 30% more accurate in transcribing similar speech patterns. Researchers collected over 151 hours of recordings from participants with varying degrees of dysarthria, a speech disorder common in Parkinson’s patients, and used the data to train ASR systems.

Reduced Brain Response to Visual Cues Linked to Psychosis in Parkinson’s

People with Parkinson's disease (PD) who experience visual hallucinations have reduced brain responses to unexpected visual changes, a marker known as visual mismatch negativity (vMMN). Using EEG, researchers compared brain activity in PD patients with and without hallucinations and discovered that those with hallucinations showed weaker vMMN signals.
