AI system can measure heart rhythms using smart SPEAKERS

Amazon's Echo and other smart speakers like the Google Home could be used to monitor the rhythm of a person's heart. Academics created an AI-powered device which monitors regular, and irregular, heartbeats using the same tools found in smart speakers. The prototype, which was built in a lab but could be incorporated into speakers in the future, was found to be almost as good as medical devices in hospitals. The search for heartbeats begins when a person sits within one to two feet of the smart speaker. Then the system plays an inaudible continuous sound, which bounces off the person and then returns to the speaker.
