AN APP that can detect Covid in your voice has been ­developed by researchers.

The AI-powered tech is easier to use and more accurate than lateral flow tests, it is claimed.

Researchers have developed an app that can detect Covid in your voice in less than a minute, and claim it is more accurate than lateral flow tests

The myCOPD app asks users to cough, breathe deeply then read a short sentence three times.

In tests, it correctly identified positive cases 89 per cent of the time and negative cases 83 per cent in less than a minute.

Researcher Wafaa Aljbawi, from the University of Maastricht, in the Netherlands, said: “The tests can be provided at no cost and are simple to interpret.

“They could be used at the entry points for large gatherings, enabling rapid screening.”

She said lateral flow tests missed 44 out of 100 positive cases, while the app would miss just 11.

But the app may wrongly diagnose 17 in 100 non-infected people, compared with one in 100 for lateral flow.

Covid usually affects the upper respiratory tract and vocal cords, leading to changes in a person’s voice.

The app uses data from Cambridge University, which collected 893 audio samples from 4,352 participants including 308 Covid patients.

The study used a voice analysis technique, Mel Spectrogram.

To distinguish Covid patient voices from non-sufferers, the team built an artificial intelligence system based on neural networks which mimic how the human brain operates.
