Researchers have developed an artificial intelligence-based system that can listen to your cough and indicate whether you have COVID-19.

With the new Coughvid app, developed by five researchers at EPFL’s Embedded Systems Laboratory, you can record your cough on a smartphone and find out whether you might have COVID-19. So how can a smartphone app detect the new coronavirus? “According to the World Health Organization, 67.7% of people who have the virus present with a dry cough – producing no mucus – as opposed to the wet cough typical of a cold or allergy,” says David Atienza, a professor at EPFL’s School of Engineering who is also the head of the laboratory.

Free and anonymous

Once the app is available, users will simply need to install it and record their cough – the results will appear immediately. “We wanted to develop a reliable, easy-to-use system that could be deployed for large-scale testing,” says Atienza. “It’s an alternative to conventional tests.” In addition to being easy to use, the app has the advantage of being non-invasive, free and anonymous. “The app targets to reach a 70% accuracy rate when enough data from a broad spectrum of patients is collected and used for testing,” he adds. “That said, people who think they may have the disease should still go see their doctor. Coughvid is not a substitute for a medical exam.”

Using artificial intelligence to help patients

Coughvid uses artificial intelligence to distinguish between different types of coughs based on their sound. “The idea is not new. Doctors already listen to their patients’ coughs to diagnose whooping cough, asthma and pneumonia,” says Atienza.

To develop their system, the team is collecting as much data as possible to train the app to distinguish between the coughs of people with COVID-19, healthy people, and people with other kinds of respiratory ailments. COVID-19 patients who would like to contribute to the development work can record their cough at https://coughvid.epfl.ch/ or on the Coughvid mobile app.
