AI-powered app analyzes the user's voice to determine if they are infected with the coronavirus

Americans are increasingly being spotted wearing face masks in public amid the coronavirus pandemic, as are people are around the globe. Soon, the Centers for Disease Control and Prevention (CDC) may advise all Americans to cover their faces when they leave the house, the Washington Post reported. The agency is weighing that recommendation after initially telling Americans that they didn't need to wear masks and that anything other than a high-grade N95 medical mask would do little to prevent infection any way. Research on how well various types of masks and face coverings varies but, recently, and in light of the pandemic of COVID-19, experts are increasingly leaning toward the notion that something is better than nothing. A University of Oxford study published on March 30 concluded that surgical masks are just as effective at preventing respiratory infections as N95 masks for doctors, nurses and other health care workers.
