ABSTRACT:
An automatic speech recognizer only responsive to acoustic speech utterances is activated only in response to acoustic energy having a spectrum associated with the speech utterances and at least one facial characteristic associated with the speech utterances. In one embodiment, a speaker must be looking directly into a video camera and the voices and facial characteristics of plural speakers must be matched to enable activation of the automatic speech recognizer.
