An anonymous reader writes: Ever wondered what Siri would look like? Now she may have the possibility of receiving a face to go with her voice. New research conducted at Cambridge Research Lab and the University of Cambridge's Department of Engineering has resulted in Zoe: a digital, talking head that can express a range of human emotions on demand. The virtual face can display emotions such as happiness, anger and fear, and can even suit its voice to any feeling that the user wants it to simulate. Creepily life-like, the face is based on actress Zoe Lister, best known for her role in the Channel 4 series, Hollyoaks.
