1. A method for automatically animating lip synchronization and facial expression of three-dimensional characters comprising:

  • obtaining a first set of rules that define output morph weight set stream as a function of phoneme sequence and time of said phoneme sequence;

    obtaining a timed data file of phonemes having a plurality of sub-sequences;

    generating an intermediate stream of output morph weight sets and a plurality of transition parameters between two adjacent morph weight sets by evaluating said plurality of sub-sequences against said first set of rules;

    generating a final stream of output morph weight sets at a desired frame rate from said intermediate stream of output morph weight sets and said plurality of transition parameters; and

    applying said final stream of output morph weight sets to a sequence of animated characters to produce lip synchronization and facial expression control of said animated characters.
