A new app could determine if you may have contracted the coronavirus just by analyzing your voice.
Researchers at Carnegie Mellon University have developed an AI-powered system that analyzes your voice and provides a score on the likelihood it contains signatures of the virus.
The technology picks up breathing patterns and other vital parameters, as the coronavirus greatly affects the lungs.
The team is urging the public, healthy or infected, to share a recording of their voice in order to help improve the algorithm.

The app, called COVID Voice Detector, is still in the early stages and comes with the disclaimer that it is not approved by the FDA or CDC, and ‘it shouldn’t be used as a substitute for a medical test or examination,’ Futurism reported.
The coronavirus (COVID-19) first made headlines in December 2019, when cases began popping up in Wuhan, China.
Within a few weeks it had spread throughout the country and has now infected nearly every part of the world.
As of Tuesday, there are more than 786,000 cases and over 37,000 deaths reported around the globe.
And with the cases continuing to rise, so has the shortage of test kits available, but that is why Carnegie Melon has developed their new app.

Benjamin Striner, a Carnegie Mellon graduate student who worked on the project, said in an interview with Futurism: ‘I’ve seen a lot of competition for the cheapest, fastest diagnosis you can have.
‘And there are some pretty good ones that are actually really cheap and pretty accurate, but nothing’s ever going to be as cheap and as easy as speaking into a phone.
Although the app is still in the development stage, Striner believes it could be vital to healthcare officials once it is released.
It uses a ranking from one to 10 when analyzing the person’s voice – the higher the ranking the more likely the individual has coronavirus.
To use the app, the person would cough several times when prompted and say a few different vowel sounds and recite the alphabet.
And the tool then presents a score in a download progress bar.
The team has gathered recordings from 19 individuals who have tested positive for the virus and those with other viruses in order to train the algorithm to spot coronavirus.
However, as the app says it should not be used as a sole means of diagnoses and Striner noted that they have yet to test the accuracy because they do not ‘have the verified test instance’ they need.
If it comes from a healthy person, we then have examples of what ‘healthy’ sounds like,’ he told Furturism,
‘If it comes from a person who has some known respiratory condition, we then know what that condition sounds like.
‘The system will use all that data as counterexamples, and for disambiguating COVID signatures from those of other confusing conditions.’
DO FACE MASKS MAKE A DIFFERENCE AND WHAT SHOULD YOU WEAR IF YOU CAN’T GET ONE?
Americans are increasingly being spotted wearing face masks in public amid the coronavirus pandemic, as are people are around the globe.
Soon, the Centers for Disease Control and Prevention (CDC) may advise all Americans to cover their faces when they leave the house, the Washington Post reported.
The agency is weighing that recommendation after initially telling Americans that they didn’t need to wear masks and that anything other than a high-grade N95 medical mask would do little to prevent infection any way.
FACE MASKS DO HELP PREVENT INFECTION – BUT THEY’RE NOT ALL CREATED EQUAL
Research on how well various types of masks and face coverings varies but, recently, and in light of the pandemic of COVID-19, experts are increasingly leaning toward the notion that something is better than nothing.
A University of Oxford study published on March 30 concluded that surgical masks are just as effective at preventing respiratory infections as N95 masks for doctors, nurses and other health care workers.
It’s too early for their to be reliable data on how well they prevent infection with COVID-19, but the study found the thinner, cheaper masks do work in flu outbreaks.
The difference between surgical or face masks and N95 masks lies in the size of particles that can – and more importantly, can’t – get though the materials.
N95 respirators are made of thick, tightly woven and molded material that fits tightly over the face and can stop 95 percent of all airborne particles, while surgical masks are thinner, fit more loosely, and more porous.
This makes surgical masks much more comfortable to breathe and work in, but less effective at stopping small particles from entering your mouth and nose.
Droplets of saliva and mucous from coughs and sneezes are very small, and viral particles themselves are particularly tiny – in fact, they’re about 20-times smaller than bacteria.
For this reason, a JAMA study published this month still contended that people without symptoms should not wear surgical masks, because there is not proof the gear will protect them from infection – although they may keep people who are coughing and sneezing from infecting others.
But the Oxford analysis of past studies – which has not yet been peer reviewed – found that surgical masks were worth wearing and didn’t provide statistically less protection than N95 for health care workers around flu patients.
However, any face mask is only as good as other health and hygiene practices. Experts universally agree that there’s simply no replacement for thorough, frequent hand-washing for preventing disease transmission.
Some think the masks may also help to ‘train’ people not to touch their faces, while others argue that the unfamiliar garment will just make people do it more, actually raising infection risks.
If the CDC does instruct Americans to wear masks, it could create a second issue: Hospitals already face shortages of masks and other PPE.
WHAT TO USE TO COVER YOUR FACE IF YOU DON’T HAVE A MASK
So the agency may recommend regular citizens use alternatives like cloth masks or bandanas.
‘Homemade masks theoretically could offer some protection if the materials and fit were optimized, but this is uncertain,’ Dr Jeffrey Duchin, a Seattle health official told the Washington Post.
A 2013 study found that next to a surgical mask, a vacuum cleaner bag provided the best material for a homemade mask.
After a vacuum bag, kitchen towels were fairly protective, but uncomfortable. Masks made of T-shirts were very tolerable, but only worked a third as well as surgical mask. The Cambridge University researchers concluded that homemade masks should only be used ‘as a last resort.’
But as the pandemic has spread to more than 164,000 people worldwide, it might be time to consider last resort options.
