Researchers at the Massachusetts Institute of Technology (MIT) have detected almost unnoticeable changes in the voices of people with coronavirus but without symptoms.
When the coronavirus circulates in the body, and even if no symptoms appear, there are biological clues in the voice, concludes a team of researchers from the Lincoln laboratory of the Massachusetts Institute of Technology (MIT) led by Thomas Quatieri.
In fact, scientists have analyzed the coordination between the “vocal subsystems responsible for respiration, phonation and articulation” and the neurological manifestations of the disease.
And when the respiratory voices are damaged by the virus, the variety of sounds produced is reduced, explains the study published in the IEEE, a specialized journal of the Institute of Electrical and Electronics Engineers. These biological indices result from disturbances caused by the infection arising from the movement of the muscles via the respiratory, laryngeal and articulatory systems.
The Lincoln laboratory is studying the changes in voice caused by amyotrophic sclerosis and Parkinson’s disease. In context of the epidemic, Thomas Quatieri and his team focused on the interviews of five celebrities tested positive for coronavirus, but asymptomatic.
Although the research is only in the initial phase, the first results open the way to a more detailed study of vocal changes. Work that can also be promising in the use of mobile applications to screen people with the disease, especially those without symptoms.
An experiment is underway, in particular to integrate voice screening from Covid-19 to the VoiceUp application originally developed to study the link between voice and depression, says MedicalXpress.
