Claims (1)
- SAMDF를 이용한 기본 주파수와 제1포만트의 비율 측정방법에 있어서, 음성신호를 대수의 진폭 스펙트럼으로 변환한 다음에 최대의 스펙트럼을 이루는 위치를 결정하여 스펙트럼 상에서 제1포만트를 구하는 제1과정과, 상기 제1과정에서 구해진 스펙트럼을 SAMDF 함수에 가하여 SAMDF 함수에 통과된 스펙트럼 중에서 첫 봉우리에서 시작하여 최소의 골을 이루는 주파수 지연값을 기본 주파수로 정하는 제2과정 상기 제1포만트 대 기본 주파수의 비율을 측정하는 제3과정을 포함하는 것을 특징으로 하는 SAMDF를 이용한 기본 주파수와 제1포만트의 비율 측정방법.
