How Microsoft's new model turns audio into a realistic talking head
Researchers can turn any picture into a portrait that can speak
Picture this (heh): you have a favorite photo of a loved one, and with a simple voice recording, you could magically bring that picture to life and have a lifelike conversation. Sound like science fiction? Thanks to a new AI system from Microsoft Research, it's now reality.
The paper, published today, shows how AI can animate a still portrait into a realistic 3D talking avatar, complete with authentic facial expressions, lip syncing, and head movements that match a given audio clip. The implications are profound - and yes, a little mind-bending!
