Abstract

본 발명은 차량 주행중 차량에 설치된 셀룰러 폰의 음성다이얼링에 관한 것으로서, 특히 국어의 음운 형태상 오인식이 빈번한 숫자음 인식을 보완하여 인식율을 향상시킬 수 있는 핸드프리 음성 다이얼링 시스템의 음성인식 방법에 관한 것이다.The present invention relates to a voice dialing of a cellular phone installed in a vehicle while driving a vehicle, and more particularly, to a voice recognition method of a hand-free voice dialing system that can improve recognition rate by supplementing frequent digit recognition of a phonological form of Korean language. .

본 발명은 핸드프리 음성 다이얼링 시스템을 구현할 때 국어의 음운 형태상 숫자음 인식에 있어 두음절 단위가 단어보다 떨어질 수 밖에 없는 문제점을 고려하여 입력음성 인식 알고리즘 변경으로 첫번째 인식단어가 오인식일 경우에는 2차 후보단어를 선택하게 함으로써 화자 독립음성인식 기술을 배경으로 하는 음성다이얼링 시스탬에서의 음성인식율을 현저히 향상시킬 수 있게 된다.The present invention considers the problem that two syllable units must be lower than words in the recognition of digits in Korean phonological form when implementing a hand-free voice dialing system. By selecting the second candidate word, the speech recognition rate in the speech dialing system based on the speaker independent speech recognition technology can be significantly improved.

Claims (1)

핸드 프리 음성 다이얼링 시스템의 음성인식 방법에 있어서, 핸드프리 마이크를 통하여 입력되는 음성신호를 다지털화하여 끝점을 검출한 후 음성의 특정신호를 추출하는 제 1 단계, 이 제 1 단계에서 추출한 후 특정신호와 미리 저장된 기준음성 특징신호들의 유사도를 계산하여 단어인식군에서 가장 가까운 단어를 1차 인식단어로 선택하고, 두 번째 가까운 단어를 2차 인식단어로 선택하는 제 2 단계 및, 숫자음 입력 확인 안내음 송출시 1차 인식단어를 출력하여 오인식일 경우 2차 인식단어를 출력하여 확인 받는 제 3 단계를 포함하는 것을 특징으로 하는 핸드프리 음성 다이얼링 시스템의 음성인식 방법.In a voice recognition method of a hand-free voice dialing system, a first step of extracting a specific signal of a voice after detecting an end point by digitalizing a voice signal input through a hand-free microphone, and then extracting the specific signal after the first step And a second step of selecting the closest word in the word recognition group as the first recognition word and calculating the second closest word as the second recognition word by calculating the similarity of the pre-stored reference voice feature signals. And a third step of outputting the first recognition word at the time of sound transmission and outputting the second recognition word to confirm the second recognition word. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
