App does COVID testing by hearing your voice

Since the start of the COVID-19 epidemic, PCR tests have burdened everyone who wanted to confirm their infection with the virus. PRC test has a high price, and their results usually take between 4 to 6 hours.
To solve this problem, researchers have discovered a new artificial intelligence application that can know your infection with the virus through your voice, more accurately than a home self-test for COVID-19.
“myCOPD,” asks users to cough and breathe deeply and then read a short sentence three times to test if they carry the COVID-19 virus.
The tests also correctly identified 89 percent positive cases and 83 percent negative issues in less than a minute, according to The Sun. But the app could misdiagnose 17 out of every 100 uninfected people, compared to one in 100 for self-test.
The app uses data from the University of Cambridge, which collected 893 voice samples from 4,352 participants, including 308 COVID-19 patients.
The study also used voice analysis technology, Mel Spectrogram, to distinguish the voices of Covid patients from those who were not infected. The team built an artificial intelligence system based on neural networks that simulate how the human brain works.
It is noteworthy that the Coronavirus usually affects the upper respiratory tract and vocal cords, which leads to changes in a person’s voice.
