Abstract: 본 발명은 음성인식기에서 가비지 및 반단어 모델 기반의 거절 기술에 관한 것으로, 특히 비음성을 거절하기 위한 가비지 모델(garbage model), 음소 유사도에 기반하는 반단어 모델(anti-word model) 구성법, 이들을 통합한 거절 네트워크, 거절 네트워크에 대한 고속 재평가를 위한 인접 프레임 간의 유사도에 근거한 프레임 제거법(frame dropping)을 동원하여 인식된 결과를 거절하는 것을 특징으로 한다. 본 발명에 의하면, 종래 음성인식을 위한 발성사전에 등록되어 있지 않은 미등록 어휘나 비문법적 어휘의 입력뿐만 아니라, 등록되지 않은 음향-음성학적 입력 신호의 입력에 대해 효과적인 거절 기능을 수행할 수 있으며 고속의 거절평가가 가능해짐으로써 인식성공률이나 반응시간에서 음성인식기의 성능 향상을 도모할 수 있다.

Abstract: PURPOSE: An utterance verification apparatus based on a word reliability threshold and a method thereof are provided to apply different reliability threshold to each word recognized in a word-based utterance verification system with respect to a voice recognition result. CONSTITUTION: A phoneme segment information extractor(130) extracts phoneme segment information with the analysis of a recognized word. Likelihood value calculators(140,150) calculate an likelihood value for the extracted phoneme and half-phoneme. A threshold calculator(170) calculates a threshold value corresponding to the recognized word. A comparator(190) compares the threshold value with an LLR(Log Likelihood Ratio) calculated by the likelihood value calculator. According to a comparison result, the comparator outputs or secludes a voice recognition result.
