Abstract

본 발명은 잡음환경에서 원활한 연속음성인식을 수행하기 위하여 호출명령어를 선정하고 잡음을 포함한 묵음구간과 호출명령어로 구성된 최소의 인식네트워크를 토큰으로 구성하여 입력된 음성에 대해 실시간 음성인식을 계속적으로 수행하고 이에 대한 신뢰도를 연속적으로 분석하여 연이어 들어오는 발화자의 음성을 인식하는 잡음환경에 매우 강인한 연속음성인식 시스템에 관한 것이다. 본 발명에 따른 실시간 호출명령어인식을 이용한 음성구간검출 및 연속음성인식 시스템은, 발화자가 호출명령어를 발화하면, 호출명령어를 인식한 후 신뢰도를 측정하여 상기 호출명령어를 인식하는 순간 상기 호출명령어에 연이어 발화되는 음성구간을 연속음성인식엔진에 인가함으로써 발화자의 음성을 인식하는 것을 특징으로 하여 이루어진다.
