Smartphone app listens for heart failure danger signs
NCT ID NCT07443969
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a smartphone app that listens to your voice to catch early signs of heart failure getting worse. 123 people who were in the hospital for heart failure will record their voice daily for 6 months. The app looks for voice changes that might signal a problem, but doctors won't see those results during the study—they'll be analyzed later to see if the app works.
