Patent number: 5567162Abstract: In a karaoke system capable of scoring a singing of singer on an accompaniment thereof, when a voice signal of the singer is inputted, an energy detector generates a first basic frequency signal with respect to a voice signal section and inputs the first basic frequency signal to a comparator. And then, an audio signal in the voice signal section is inputted to the comparator as a second basic frequency signal. The comparator compares the first and second basic frequency signals with each other and calculates a difference value therebetween, and then inputs it to a microprocessor. The microprocessor outputs a signal for scoring the singing of the singer on the basis of the difference value.Type: GrantFiled: November 4, 1994Date of Patent: October 22, 1996Assignee: Daewoo Electronics Co., Ltd.Inventor: Chan Soo Park
