본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제4도는 본 발명의 차분계수에 의한 피치검출 논리블럭도.4 is a pitch detection logic block diagram according to the difference coefficient of the present invention.

Claims (1)

유성음/무성음 판정기(9)와 클리핑 회로부(10) 및 마이크로 프로세서(6)가 구비된 음성합성인식시스템에 있어서, 상기 유성음/무성음 판정기(9)와 클리핑회로부(10)를 통해 분석 및 클리핑된 신호에 대해 하나의 분석구간(1프레임)에서 연속하는 세개의 데이터(혹은 그 이상)의 차분계수를 검출하여 극대값을 결정한 후 계속해서 +10 샘플까지의 검출을 시도하여 가장 큰 피치값을 제1극대값으로 결정하고 이후 인간의 최소 피치인 30샘플떨어진 이후의 데이터에 대해 제2극대값, 제3극대값을 결정하여 피치를 검출하는 것을 특징으로 하는 음성 합성인식시스템에서의 차분계수 부호변환을 이용한 피치검출법.In the speech synthesis recognition system equipped with the voiced / unvoiced determiner 9, the clipping circuit unit 10, and the microprocessor 6, the voiced / unvoiced voice determiner 9 and the clipping circuit unit 10 analyze and clip it. The maximum difference value is determined by detecting the difference coefficient of three consecutive data (or more) in one analysis section (1 frame) and then trying to detect up to +10 samples. Pitch using difference coefficient code conversion in speech synthesis recognition system, characterized in that the first maximum value is determined and the second maximum value and the third maximum value are determined for the data after 30 samples, which are the minimum pitch of human, are detected. Detection method. ※ 참고사항 : 최초출원 내용에 의하여 공개되는 것임.※ Note: This is to be disclosed by the original application.
