The document discusses using machine learning techniques to generate human VR characters with artificial intelligence. It outlines the key components needed which include 3D face models, dialog, speech generation, and face animation matching the dialog. Generative models can be used to generate speech, images like cats and buildings, and even human faces from photos. Techniques for capturing high quality 3D face models, animating faces to match speech, and animating full body movement are presented. The goal is to put all the techniques together to generate interactive virtual human characters using AI.
