Claim 17:
18. A system for producing an avatar video, a method comprising the steps of:
an image processing model for receiving a reference image of a person's face and for extracting a plurality of characteristic features representative of a facial model XO of the person's face, the characteristic features defining a facial pose dependent on a person speaking;
a speech processing module for extracting a target phrase to be rendered over a predetermined time period during the avatar video and for providing a plurality of time intervals t within the predetermined time period;
the speech processing module configured to generate, for each of said plurality of time intervals t, speech features from the target phrase, to provide a sequence of speech features; and
an avatar rendering module for generating, using the plurality of characteristic features and sequence of speech features, a sequence of facial models Xt for each of said time intervals t, wherein the sequence of facial models Xt is generated using a recursive model.
