Researchers at MIT have used machine learning to create software capable of detecting whether a person has caught COVID-19 by analyzing their cough, a development that could eventually result in an iPhone app for daily checks.

A paper from the team published in the IEEE Journal of Engineering in Medicine and Biology claims an AI model was created that could tell the difference between asymptomatic people and those who are healthy, via analysis of recordings of forced coughs. The model is claimed to be accurate 98.5% of the time when listening to recordings of people confirmed to have had COVID-19, as well as 100 percent of asymptomatic cough recordings.

The team collected more than 70,000 recordings via a website where the public could record a series of coughs via their smartphone or other devices, [...] Combining the 2,500 confirmed samples with another 2,500 randomly selected from the data set, the AI model was trained, then tested.

It is suggested by the team that such cough analysis could be implemented into smart speakers and digital assistants to perform daily assessments.

IEEE: COVID-19 Artificial Intelligence Diagnosis using only Cough Recordings

AI techniques can produce a free, non-invasive, real-time, any-time, instantly distributable, large-scale COVID-19 asymptomatic screening tool to augment current approaches in containing the spread of COVID-19. Practical use cases could be for daily screening of students, workers, and public as schools, jobs, and transport reopen, or for pool testing to quic...
