The AI is very accurate in the first tests. After the team trained their model on tens of thousands of cough samples and dialogues, the technology recognized 98.5 percent of coughs from people with confirmed COVID-19 cases. It also identified 100 percent of the people who were ostensibly asymptomatic.
There are clear limits. The technology is not intended to diagnose symptomatic people, as they may have other conditions that produce similar behavior. And while it’s quite capable, you don’t want to use this for a final verdict on whether or not you’re infected.
However, this is not a theoretical exercise. Scientists are developing an “easy to use” application that could be used as a virus screening tool. You may just have to cough into your phone every day to determine if it is safe for you to go out. The researchers even suggest that this could end pandemics if the tool were always listening in the background, although that’s a big “yes” when it would likely raise privacy concerns.
