This AI-powered app detects COVID-19 using just your voice with 80% accuracy

Detecting COVID-19 is not easy, because the symptoms it causes vary greatly from one person to the next. If you have some symptoms such as a sore throat, fever, cough, or loss of smell or taste, you’ll know that you need to get yourself checked.

That’s why companies like Vocalis are developing solutions to pre-screen people using simple technologies such as voice and mobile apps to predict if someone has COVID-19.

What problem is it solving?
Screening folks for coronavirus or any other disease is difficult unless you go to a test center in person. So Vocalis has developed an AI that identifies voice characteristics of patients having various diseases without needing to visit a hospital or stressing their local healthcare systems.

Plus, screening methods such as temperature guns can’t detect asymptotic patients. Vocalis’ solution could help in those situations.

Where’s the AI?
Vocalis collects a lot of data related to a person’s voice. It has developed a technology that identifies characteristics of a potential disease based on the analysis of voice collected from a person.

The firm’s algorithm extracts 512 features from a voice sample and makes an image — a spectrogram — with which it can diagnose possible diseases.

When the company aims to help detect a specific disease, it first holds clinical trials to recognize what kind of voice recordings it would need to collect to identify it, and what signatures in the audio it will need to pinpoint.

For instance, to detect COVID-19 the AI needs to identify characteristics of symptoms such as fever, headache, and shortness of breath.
