Summary

This study looked at whether speech features—like how people sound and what they say—can help detect or predict confusion caused by liver disease (hepatic encephalopathy). Researchers recorded speech tasks from 251 participants with cirrhosis and tracked their thinking skills and confusion episodes over time. The goal is to find a simple, non-invasive way to monitor brain health in people with liver problems.
