Coughvid Diagnostic Test


École Polytechnique Fédérale de Lausanne is developing an diagnostic test app called “Coughvid” that would listen to people cough and use AI to determine whether they sound like a COVID-19 patient. The app is aimed to help reduce the number of people going to doctors demanding for a test when they don’t exhibit the symptoms and to understand where the virus is spreading.


  • According to WHO, COVID-19 patients exhibt a dry cough — a chirping intake of breath at the end — that differed from typical wet cough people experience with the common cold or allergies.
  • AI technology is used to distinguish between different kinds of coughs the same way doctors listen to patients’ cough.
  • Volunteers can upload their cough recordings to the project’s website.
  • Users are kept anonymous, but they are asked for permission to save their location.
  • The app also has instructions on how to properly and safely test your coughing using a phone.


  • Although the app has been reported to have a 70% accuracy rate, it’s AI is still in the process of learning from more data sets as more people try it out.
  • More than 15,000 audio samples of people coughing have been gathered, 1,000 of which came from people who reported being diagnosed with COVID-19.
  • Once completed, the Coughvid app could be used as a tool to recommend whether users should seek out a coronavirus test or further treatment.
