Almost imperceptible changes have been detected by a team of researchers from the Lincoln laboratory in Massachusetts Institute of Technology (WITH) in the voices of people with covid-19 but who have no symptoms. These people are said to be asymptomatic.
Lincoln laboratory studies changes in voice caused by sclerosis amyotrophic and Parkinson’s disease. The researchers’ study was published in the IEEE, a specialized journal of the Institute of Electrical and Electronics Engineers.
Led by Thomas Quatieri, the team analyzed, in the context of the epidemic, the coordination between the “vocal subsystems responsible for respiration, phonation and articulation” and the neurological manifestations of the disease.
Scientists have noticed that the variety of sounds produced is reduced when the airways are damaged by the virus. These biological indices result from disturbances caused by the infection born from the movement of muscles via the respiratory systems, laryngeal and articulatory, reports Sputnik.
Especially in in this case, they focused more on interviews with five celebrities who tested positive for coronavirus, but who were asymptomatic.
The research is only in the initial phase. The first results, however, pave the way for a more detailed study of voice changes, work that could prove promising in the use of mobile applications to screen people with the disease, especially asymptomatic ones.
A To this effect, MedicalXpress indicates that an experiment is underway to integrate voice screening for Covid-19 into the VoiceUp application initially developed to study the link between voice and depression.
