Those people who still answer the phone may know that feelings: As soon as I hear a voice I think about what the other person looks like. There is Google, yes, but some people actually manage to hide their appearance online. Anyone who feels addressed, may like to contact me and teach me this art.
Anyway, researchers at MIT have developed an Artificial Intelligence that listens to a voice and then creates a face to it. That works pretty easy. The MITs took millions of Youtube videos as training material, so the AI was able to calculate a connection between voice and face.
Assuming that everyone is on Youtube today, the AI has plenty of opportunities to cheat. It just looks for the real face to every voice. But that’s just my bad assumption. I would like to have the software.
