A method of simulating movement during speech. The method includes deriving the timing and features of linguistic stress from an audio source (100). On/off characteristics of speech and the rate of speech are also derived from the audio source (200, 300). Stresses are categorized based on the feature of the stresses, the relationship between the stresses, and the on/off characteristics of speech (400). Appropriate gestures are chosen for each stress and are placed relative to the stresses (600). Gestures are modified by the rate of speech. New gestures are introduced and existing gestures are modified based on rules which examine the distribution of gestures in the speech and the on/off characteristics of speech (500, 700). Background movement is generated, consisting of states and rules for choosing states and transitioning between them based on the on/off characteristics of speech and the rate of speech.
