Abstract

본 발명은 씨디(CD) 또는 비디오-씨디(video-CD)의 음성신호와 마이크의 음성신호를 합성하는 노래방 기능이 있는 기기의 음성신호 합성장치에 관한 것이다. 종래의 노래방 기능이 있는 기기의 음성신호 합성장치를 사용하여 노래를 부를 경우에는 노래하는 사람의 목소리의 크기가 반주음의 크기보다 작을 경우에는 노래하는 사람의 목소리가 반주음에 묻혀서 노래소리가 잘 들리지 않으며, 또한 목소리를 크게하면 변환된 음성신호에서 찌그러짐이 발생함으로써 음질이 고르지 못한 문제점이 있었다. 따라서, 본 발명에는 사용자가 노래를 할 때 사람 목소리 성분이 많은 주파수 대역을 밴드패스하는 한편, 재생되는 씨디 또는 비디오-씨디의 원음에서 상기 사람 목소리 성분이 많은 주파수 대역을 리젝션 시킨후에 반주음 신호와 사람 목소리 신호를 합성함으로써, 노래하는 사람 목소리가 반주음에 묻히지 않고 재생되어 사용자가 노래를 부를 때 반주음과 반주음에 섞인 자신의 목소리를 분명하게 들을 수 있게 하였다.The present invention relates to a voice signal synthesizing apparatus of a device having a karaoke function for synthesizing a voice signal of a CD or a video-CD and a voice signal of a microphone. When singing using a voice signal synthesizing apparatus of a device with a conventional karaoke function, when the volume of the singer's voice is smaller than the accompaniment sound, the singer's voice is buried in the accompaniment sound, so There was a problem that the sound quality was uneven because the sound was not heard and the voice was louder, so that distortion occurred in the converted voice signal. Therefore, in the present invention, when the user sings, the bandpasses a frequency band containing many human voice components, while accommodating the accompaniment signal after rejecting a frequency band containing many human voice components from the original CD or video-CD. By synthesizing the vocal and human voice signals, the singer's voice is played back without being buried in the accompaniment so that the user can clearly hear his / her voice mixed with the accompaniment and accompaniment when singing.
