11. A method for use in synthesizing audio-visual content in a video image processor, said method comprising the steps of: receiving audio-visual input signals that represent a speaker who is speaking; extracting (i) audio features of the speaker's speech and (ii) visual features of the speaker's face from the audio-input signals; creating audiovisual input vectors from (i) the extracted audio features and (ii) the extracted visual features, wherein each audiovisual input vector comprises a hybrid logical unit that exhibits properties of both (a) the phonemes and (b) the visemes; creating audiovisual configurations from the audiovisual input vectors, wherein the audiovisual configurations comprise speaking face movement components in an audiovisual space; and performing a semantic association procedure on the audiovisual input vectors to obtain an association between phonemes that represent the speaker's speech and visemes that represent the speaker's face for each audiovisual input vector.
12. The method as claimed in claim 11 , further comprising: analyzing an input audio signal of a speaker's speech, wherein analyzing includes: extracting audio features of the speaker's speech from the input audio signal; finding corresponding video representations for the extracted audio features using a semantic association procedure; and matching the corresponding video representations with the audiovisual configurations.
