The agent accepts Chinese textual input and generates in real time a three-dimensional (3D) talking face that is lip-synchronized to Cantonese synthesized speech. LinLin has a 3D face model that consists of many position coordinates and we have defined 16 static visemes based on this model. 3D face rendering is achieved by a blending technique that computes linear combinations of the static visemes to effect smooth transitions.     Lip-synchronization follows the syllable initial/final durations of the synthesized speech. LinLin can also display blinking, head movements, facial emotions (where “happy” and “worry” are static models with a smile and medially upturned eyebrows respectively), as well as gestures with her hands. LinLin with different facial emotions ("happy" left, "worry" right)     LinLin was selected to represent Chinese University of Hong Kong in the Challenge Cup Competition 2003 – a biennial competition where over two hundred universities across China compete with their science and technology projects. LinLin was awarded Level 2 Prize in this competition. Related Publication: Wang, J. Q., Wong, K. H., Heng, P. A., Meng, H., Wong, T.
