Abstract
본 발명은 음성인식 시스템의 중심이 인식장치에 관한 것으로서, 이는 필러모델로 적용어휘 집합을 대상으로 한 필러모델을 간단하게 모델링하여 중심어와 비슷한 음성구간이 발음되어 발생되는 오류알람의 비를 줄이고 간단한 비교연산만을 수행하여 중심어를 인식하도록 하고, 아울러 사용자가 중심어 포함여부에 관계없이 다양한 형태로 음성을 입력하여도 만일 중심어가 존재하면 그 중심어만을 스포팅해서 인식하도록 한 것이다. 이와 같은 본 발명은 입력 음성신호를 양자화하여 음성을 대표하는 특징벡터를 추출하는 음성특징 추출과정과, 상기 추출된 음성 특징벡터열을 데이타 베이스화된 중심어모델의 중심어와 이에 대응하는 필러보델의 비중심어를 이용하여 중심어 누적 확율값과 이에 대응되는 비중심어의 확율값을 추출하는 중심어 추출과정과, 상기 추출된 중심어의 확율값과 비중심어 확율값의 비를 연산하여 중심어를 판정하는 중심어를 판정하는 중심어판단과정으로 이루어짐으로서 달성된다.The present invention relates to a recognition apparatus centered on a speech recognition system, which simply models a filler model for a set of applied vocabulary as a filler model, thereby reducing the ratio of error alarms generated by sounding similar to the central word. Only the comparison operation is performed to recognize the central word, and even if the user inputs the voice in various forms regardless of whether the central word is included, if the central word exists, only the central word is recognized. As described above, the present invention provides a speech feature extraction process for quantizing an input speech signal and extracting feature vectors representing speech, and a center word of the extracted central feature vector string based on a database based on a central word model and a non-centered word of pillarbodel A core word extraction process of extracting a central word cumulative probability value and a corresponding non-central word probability value using the method, and calculating a ratio of the probability value and the non-central word probability value of the extracted central word to determine the central word for determining the central word. This is accomplished by making a judgment process.
