Abstract

본 발명은 음성신호 가변재생시 배경음 합성방법 및 그 장치에 관한 것으로서, 기록매체에 기록되어 있는 합성신호(음성신호+배경음)를 변속 재생할 때 배경음의 전압레벨이 급격히 감소하여 신호특성을 상실하는 경우에도 별도의 외부 배경음을 이용하여 항상 깨끗한 음질을 청취할 수 있도록 하기 위하여, 가변재생모드가 선택되면, 음성신호 변속처리부를 제어하여 합성신호 변속재생모드를 수행하는 제1과정; 상기 제1과정에 의해 변속재생된 합성신호와 외부에서 인가된 별도의 외부 배경음을 합성하여 출력하는 제2과정을 수행하도록 하였다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of synthesizing a background sound and a device thereof for variable reproduction of a voice signal. In the case of shifting and reproducing a synthesized signal (voice signal + background sound) recorded on a recording medium, when the voltage level of the background sound is rapidly decreased, signal characteristics are lost. In order to always listen to the clean sound quality using a separate external background sound, if the variable playback mode is selected, the first step of performing a synthesized signal shift playback mode by controlling the voice signal shift processor; The second process of synthesizing and synthesizing the synthesized signal shifted and reproduced by the first process with a separate external background sound applied from the outside is performed.

또한, 음성신호 변속처리부에서 출력된 변속 합성신호와 외부에서 인가된 외부 배경음을 하성하여 출력하는 합성기; 및 상기 음성신호 변속처리부에 제어신호를 출력하여 외부에서 인가된 합성신호의 변속동작을 제어하도록 한 마이크로 컴퓨터를 구비하였다.In addition, a synthesizer for lowering and outputting the shift synthesis signal output from the voice signal shift processor and an external background sound applied from the outside; And a microcomputer configured to output a control signal to the voice signal shift processor to control a shift operation of the synthesized signal applied from the outside.
