G4 - A Multilingual Virtual Performer
Virtual performers have been heavily used in computer games, TV programmes
and movie production. However, lip synchronization is still a tedious
and difficult task. Animators have to spend hours and hours of time to
fine tune the parameters in order to achieve realistic effect. We developed
a system that allows us to easily model virtual characters with realistic
and natural talking and singing abilities. It provides natural human-computer
interface. The system offers a real-time text-to-speech synthesis. Lip
shape parameters are generated and fed to the rendering engine for facial
animation in real-time. Since the system is based on International Phonetic
Alphabet (IPA) standard, it supports multi-language including Cantonese,
Mandarin, Japanese, and English. Hence it can be easily configured for
both local and foreign markets. Besides realistic rendering, it also
allows stylish rendering such as comic-style rendering. All these processing
are done on an ordinary PC. With this system, animators can easily produce
lip-synchronized character facial animation. There are a lot of applications
including character modeling in computer games, TV and movies, computer-assisted
education and even the latest virtual idol.
