Abstract

PURPOSE: To prevent the rejection of correct recognition results under low-noise conditions by automatically setting a rejection criterion depending upon an ambient noise state.
CONSTITUTION: This unit consists of recognition processing part 20 for the recognition of input voices, noise measurement part 40 for the measurement of the power level of circumferential noises, and rejection processing part 50 processing the rejection of recogniton results from recognition processing part 20 on the basis of the rejection criterion controlled by the power level of circumferential noises. As a result, the rejection criterion is set automatically at its optimum depending upon the state of ambient noises and it is made possible to attain the definite rejection of error recognition under high-noise conditions and the reduction of rejecting correct recognition results under low-noise conditions.
