Infectious diseases affect the tone and the voice volume of the person, as the inflammation in the respiratory system affects the intensity of exhalation of air and muscle. According to this principle, it is possible to identify hidden emerging coronavirus, according to scientists from the Massachusetts Institute of technology.
They conducted a computer analysis and compared the recorded voices of people infected COVID-19, but not yet having experienced symptoms with their interview when they were healthy. It turned out that the virus provokes an increase in muscle tension and impedes their movement, ultimately decreasing the diversity of audio signals and there are “vocal” biomarkers that indicate coronavirus infection, extracts from the report of the doctors brought the portal the Telegraph.
