Will Fast corona tests and also the far more complex PCR tests – which often mean you have to wait days for the results – soon become superfluous? Yes, at least to a certain extent. That is according to a research team headed by Prof. Dr. Bj\u00f6rn Schuller at the University of Augsburg<\/a> in Germany. They are developing an app with which infection with the SARS-CoV-2-Virus can be identified by speech. “The app could provide real-time data on the movements and transmission patterns of people infected with corona,” Schuller is quoted by the German news service dpa<\/a>.

<\/strong>The scientist is a specialist in artificial intelligence and has been researching a speech recognition app since March. One that can determine whether a person is infected with the coronavirus on the basis of speech patterns. The researchers started out by using voice recordings from the Chinese city of Wuhan. However, since the virus is now widely spread in Germany, they are now using voice recordings from Germany to train the AI.<\/p>\n\n\n\n

Also in Italy scientists are working on a similar method. Over the past few months, Giovanni Saggio, professor at the Department of Electronic Technology at the University of Tor Vergata in Rome, Italy, has developed a corona voice test. Patients from a number of Italian hospitals, including the Pavia Polyclinic (which treated Italy\u2019s first corona patient in February), were asked to speak two short, set texts and cough three times. The recording was then processed by\u00a0VoiceWise<\/a>, a Tor Vergata university start-up that uses artificial intelligence to detect the coronavirus (and many other diseases) via voices.<\/p>\n\n\n\n

In Austria test subjects record a text with their cell phones which contains a considerable number of vowels. These recordings are then compared by using deep neural networks with voice recordings of people with and without a corona infection. According to Schuller, computers can be trained with machine learning to recognize patterns and several thousand characteristics in the human voice that indicate feelings and illnesses. “Language is the new blood here. We use it for analysis, but we also urgently need donations so that we can improve our systems for everyone,” he explains.<\/p>\n\n\n\n
