Google is reportedly working on a built-in snore and cough detection feature for Android devices, as part of the Google Health Sensing team’s ongoing Sleep Audio Collection study.
Google says, "You must be a Full Time Googler with an Android phone to participate in this study. Environmental conditions required for this study are to have no more than one adult sleeper in the same room who does not work for a competitor company."
The company's Health Sensing team is actively working on sensing algorithms and capabilities to provide users meaningful insights into their sleep.
The "nocturnal cough and score monitoring" will likely record users' snores and coughs during their sleep via the Android devices' microphones. It's still unclear if the feature will be Pixel exclusive or will be rolled out to all Android devices. We're also not sure if the feature will have to work with a smartwatch (probably the Pixel Watch) or if it can work independently.
