Claims (4)

  1. 무음을 포함하는 음운간의 과도부를 검출하는 수단을 가지며, 이 검출된 과도부의 음성을 소정길이 추출하여 파라미터로 변환하고 이 파라미터를 인식 기본 단위로 하도록한 음성인식방법.
  2. 제1항에서, 상기 과도부를 검출하는 수단은 입력 음성신호를 인간의 청각 특성에 응하여 같게 중첩하여 음향 파라미터를 추출하는 수단과, 이 음향 파라미터의 레벨에 대하여 정규화를 행하는 수단을 가지며, 이 정규화된 음향파라미터를 복수 프레임에 걸쳐 감시하고, 상기 음향파라미터의 피크를 검출하도록한 음성과도점 검출방법을 특징으로 하는 음성인식방법.
  3. 무음을 포함하는 음운간의 과도부를 검출하는 음성과도점 검출기와, 이 음성과도점 검출기로부터의 신호에 의하여 상기 과도부의 음성을 소정길이 추출하여 파라미터로 변환하는 변환기와, 이 변환기로부터의 파라미터를 인식 기본 단위로 하는 인식기로 이루어진 음성인식장치.
  4. 제3항에서, 상기 음성과도점 검출기는 입력음성 신호를 인간의 청각 특성에 응하여 같게 중첩하여 음향파라미터를 추출하는 음성 파라미터 추출기와, 이 음성 파라미터 추출기로부터의 음향 파라미터의 레벨에 대하여 정규화를 행하는 레벨정규화기와, 이 정규화된 음향파라미터를 복수 프레임에 걸쳐 감시하고 상기 음향파라미터의 피크를 검출하는 피크검출기로 이루어진 것을 특징으로 하는 음성인식장치.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
