The system, dubbed CDCVA (COVID-19 Detection by Cough and Voice Analysis), can detect the presence of COVID-19 through voice and cough
A Luxembourg research group is about to launch a system to detect COVID-19 through the voice and cough, which will allow a better remote diagnosis and will reduce the risks of contagion through physical contact between doctors and patients.
The project, baptized as CDCVA (COVID-19 Detection by Cough and Voice Analysis), proposes an “innovative approach”, based on the artificial intelligence, to detect the virus based on the voice and cough patterns of the affected people, explains Muhannad Ismael, head of the initiative, in an interview.
“Respiratory conditions, such as dry cough, sore throat and dyspnea caused by COVID-19 they can make the voices of patients different, creating identifiable voice signatures, which can be recognized using our system, “he says.
It’s not the first time that a similar initiative is being carried out.
The university of Cambridge and Carnegie Mellon have developed an application and a platform, respectively, to collect data and create algorithms of Artificial intelligence that allow to automatically detect if a person suffers from COVID-19 from the way you cough or speak.
However, explains the expert, all the initiatives so far serve to collect data but there is no application available to detect the COVID-19 from the voice and the cough.
“Our idea is inspires advanced research (…) For sound analysis, how to automatically recognize people affected by a cold by the acoustics of their voice or distinguish between dry, wet cough“, Add.
To develop the system, a large number of voice records and cough recordings have to be collected, which are then processed through a series of methods, in order to eliminate the noises and identify the noise. cough and voice patterns.
“The ability to successfully identify COVID-19 patients from their voices is highly dependent on collecting a large dataset containing voices and coughs from patients with COVID-19“.
You also have to take records of healthy people and of individuals who may suffer from other respiratory conditions.
The pandemic of COVID-19 It is having a huge impact on healthcare systems around the world, collapsing hospitals and generating a significant number of infections among healthcare professionals.
To diagnose the coronavirus RNA tests (diagnostic), immunological tests and rapid tests are currently used mainly.
“However, these methods require a physical consultation, which increases the risk of infection for staff and patients and consumes many resources of the health systems, ”explains Muhannad Ismael.
The system in which this works group of researchers However, it is not intended to replace the other types of tests, but rather to be complementary, providing “a preliminary auxiliary evaluation of the state of health” of broad population groups, without endangering health professionals.
The same expert indicates that “it could be used as a assistance tool for making clinical decisions for the selection of candidates who will have priority in standard laboratory tests, when the number of tests is limited and must be used infrequently ”.
In addition, it could help, for example, emergency services to manage the volume of calls to identify critical cases that require rapid intervention.
The platform that will collect the data and will be released in september, will be accessible in eight languages (English, French, German, Luxembourgish, Spanish, Russian, Serbian and Arabic) to reach the largest number of participants from all over the world.
In addition to voice data, you will gather information on age, gender, country, smoking habits, symptoms, comorbidities (eg asthma, allergies, chronic obstructive pulmonary disease, etc.) and COVID-19 testing status.
The information will be anonymous, to protect the Privacy and prevent the participants from being identified.
Although at the moment the project is in Test phase and its mode of use has not yet been considered in detail, the objective is to help in the efforts to combat the pandemic of COVID-19 globally and that different countries can use it, explains Muhannad Ismael.
In the initiative, funded by the Luxembourg National Research FundResearchers from the Luxembourg Institute of Science and Technology and the University of Luxembourg participate, with the support of the country’s Institute of Health.
