21. A computer-implemented method of simulating interactive communication between a user and a human subject, comprising: receiving a voice input from the user; matching the voice input to one of a plurality of a stored phonetic clones, the phonetic clones each corresponding to a target speech phrase associated with a stored content sequence file depicting the subject, the number of stored phonetic clones being greater than the number of stored content sequence files, the subject being a human recorded on video, the content sequence including contemporaneously-recorded audio of the human that is played simultaneously with the video of the human, wherein the video of the human includes a contemporaneously-recorded head and mouth of the human, wherein the content clip is free of any superimposed facial features; creating a transition between the content clip and the second content sequence by frame-matching a frame of the stored content sequence, the content sequence including the human subject speaking, with a frame of a second content sequence, the frame-matching being performed with respect to the recorded video of the entire head and facial features of the human subject; and in response to the matching, displaying the stored content sequence file matched to the phonetic clone and the second content sequence in succession.
