Abstract
본 발명의 워드 스포팅 시스템에서의 음성인식방법은, 등록단어와 유사하게 발음되는 음성에 대한 별도의 유사음소모델을 만들어서 그 자체를 필라로 이용하거나 상기 등록단어와 같은 음소순서로 병합하여 유사단어모델로 이용함으로써 등록단어와 비슷한 음성이 발음되어도 등록단어와 구분하여 오인식으로 인한 검출결과를 줄임으로써 워드 스포팅이 응용되는 승차권발매기, 자동판매기, 항공기 예약 서비스, 은행 서비스 등과 같이 특정 등록단어만을 인식하여도 무방한 자동음성인식장치에 적용하는 경우 매우 유용하게 인식성능을 향상시킬 수 있다.In the word spotting system of the present invention, a similar phonetic model for a voice that is pronounced similarly to a registered word may be used as a pillar or merged into a phoneme sequence such as the registered word. Even if a voice similar to a registered word is pronounced, it can be distinguished from the registered word to reduce the detection result due to a misrecognition. When applied to any automatic speech recognition device can be very useful to improve the recognition performance.
