About :

In a fraction of a second, the brain forms an opinion about a person. Facial expressions and voice determine the first impression. Artificial intelligence is also learning to interpret human emotions. Looking at a new face or the timbre of an unfamiliar voice are big challenges for our brain. In less than half a second we decide who we trust, who we like, and how intelligent we think a person is. All of this relies on the incredible power of our brain. We learn to read facial expressions as babies, and as we grow up, we continue to analyse the emotions of those around us and try to see what their faces hide. The voice plays a crucial role in all of this: speed, syntax, intonation, phonetics… All of these factors reveal what a person is feeling. But we are not the only experts who can decipher human emotions: artificial intelligence is also learning to identify faces and voices. A photo or a spoken sentence is often enough to reveal information about someone’s identity, health, emotions, and even personality. The internet is a huge and ever-growing database of faces and voices. Artificial intelligence can now detect from the timbre of our voice whether we suffer from Parkinson's, depression or even Covid-19. How does our brain work and what can artificial intelligence do? International experts give their insight into the latest scientific findings. #dwdocumentary #documentary #artificialintelligence #science ـــــ DW Documentary brings you information beyond the headlines.
