1. A robotic system for reproducing a person's facial expression and speech comprising: a robotic head comprising a speaker, a plurality of face actuators, and a computing engine connected to said speaker and said face actuators, said computing engine driving said face actuators based on a sequence of sets of control parameters while delivering speech from said speaker based on a speech segment; and at least one of a camera and a microphone for capturing a person's performance over a period of time to produce at least one of a recorded video and a recorded speech, wherein said sequence of sets of control parameters is generated from said recorded video, and said speech segment is generated from said recorded speech; wherein each of said sets of control parameters includes a time stamp and a control parameter corresponding to each of said face actuators; and said computing engine drives said face actuators at appropriate time specified by the time stamps of said sets of control parameters so that said face actuators are activated according to the corresponding control parameters to reproduce said person's facial expression.
