디지탈 신호 프로세서(4) 주변에 어드레스 디코더(5), 버퍼(6), 음성데이타롬(7), 프로그램롬(8) 및 D/A변환기(3)를 구비시켜서 음성데이타롬(7)에 에너지, 피치 선형 예측 부호화 계수를 저장한후 키보드(11)및 퍼스널 컴퓨터(10), 인터페이스부(9)를 통해 한글문자 데이타가 디지탈 신호 프로세서(4)에 입력될때 디지탈 신호프로세서(4)는 음성분석시 잔차신호 분석에 의해 얻어낸 임펄스와 노이즈 비례에 의해 프로그램롬(8)에 저장된 신호를 읽어온후 이를 다시 음성데이타롬(7)에 저장된 해당 데이타를 뽑아 음성합성시 임펄스에 노이즈를 첨가시켜 합성한후 D/A 변환기(3)와 증폭기(2)및 스피커(1)로 음원을 출력시키는 것을 특징으로 하는 잡음 첨가에 의한 자연음 합성기.In the vicinity of the digital signal processor 4, an address decoder 5, a buffer 6, a voice data ROM 7, a program ROM 8, and a D / A converter 3 are provided to provide energy to the voice data ROM 7. When the Hangul character data is input to the digital signal processor 4 through the keyboard 11, the personal computer 10, and the interface unit 9 after storing the pitch linear prediction coding coefficients, the digital signal processor 4 performs the voice analysis. After reading the signal stored in the program ROM (8) based on the impulse and noise proportion obtained by the residual signal analysis, and extracting the corresponding data stored in the voice data ROM (7) again and adding noise to the impulse during speech synthesis and synthesizing D A natural sound synthesizer by adding noise, characterized by outputting a sound source to / A converter (3), amplifier (2) and speaker (1). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
