ABSTRACT:
Compensatory values for compensating a reference pattern to match with an utterance environment of an input speech are employed for determining an environmental variation index to be input to a secondary matching controller, which is responsible for magnitudes of the index smaller than a threshold to hold a second matching section inoperative so that a recognition result of a primary matching of a previous compensated reference pattern is output, and for magnitudes of the index larger than the threshold to operate the second matching section to output a recognition result of a second matching based on a current compensated reference pattern to be stored as a subsequent reference pattern.
