Can AI listen to heart patients? stanford puts voice tool to the test
NCT ID NCT07217366
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether an AI-powered speech-to-text tool can accurately capture health information from heart failure patients. Researchers at Stanford will enroll 100 adults with heart failure to see if the tool's summaries match expert reviews. The goal is to improve communication between patients and their healthcare team.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Artificial intelligence speech-to-text tool
- What this could lead to
- If successful, this could make it easier for heart failure patients to share health updates with their care team using just their voice.
- What could go wrong
- This is a small pilot study (100 people) testing accuracy and usability, not a treatment. The tool may not work well for everyone or in real-world settings.
