AI model can detect coronavirus from the sound of a cough - but humans can't

Scientists have created an artificial intelligence model that can detect if someone has coronavirus - purely from the sound of their cough. The AI algorithm, built in the US, correctly identified patients who were infected even if they had no other symptoms. Researchers say humans are unable to hear the vital difference in the sound of someone with a cough who is asymptomatic. They say this is because Covid-19 changes the way you produce sound, even if there are no symptoms. The model, developed by the Massachusetts Institute of Technology (MIT), was 98.5% successful in detecting people who had officially tested positive for Covid-19.
