Conventionally, a karaoke system usually has a built-in duet song for two people singing the
same song in addition to a solo song as their performance music data, and is provided with two
microphones corresponding thereto .
Further, the speaker system in the karaoke system is composed of at least two speakers in stereo
correspondence.
[0004]
In such a karaoke system, either one of the two microphones is used by the singer when singing
a solo song or when singing a duet song, or two microphones are used simultaneously even if
both microphones are used simultaneously. The singing voice is output from the speaker of.
Regarding the speaker output only, for example, even if singing voice is input from one
microphone as in Patent Document 1, the same singing voice is output from two speakers, and
the singing voice is input from both of the two microphones. Even in the same case, the same
singing voice is output from two speakers.

[0006]
However, in the speaker output mode in the above-described karaoke system, in particular, when
singing a duet song, two people are actually separated by left and right and in direct listening,
they are separate left and right singing. Nevertheless, there is a problem that the singing voice is
heard from the centers of the two speakers in an overlapping state, so that the sense of reality
and the three-dimensional feeling are lacking and unnatural.

section identification means and a part-by-part audio output control means, the chorus section
identification means identifying whether or not the timing currently being played during the
performance of any duet tune is a chorus section; The part-specific audio output control means is
configured to recognize the singing voice from the first microphone or the second microphone
when the timing currently being played is identified as a period other than the chorus period by
the chorus period identification means. When it is output from both the one speaker and the
second speaker and it is identified as a chorus section, singing voice from the first microphone is
either one of the first speaker or the second speaker It is outputted from the speaker, to the
singing voice from the second microphone output from the other speaker, and configuration.
[0009]
According to the present invention, when the current playing timing of the duet song is identified
as a section other than the chorus section, the singing voice from the first microphone or the
second microphone is output from the first speaker and the second speaker And the singing
voice from the first microphone or the second microphone is output from both the first speaker
and the second speaker, and when it is identified as the chorus section, the singing voice from
the first microphone is used as the first speaker or By outputting song sound from the second
microphone and outputting the singing voice from the second microphone to the other speaker,
the singing voice input from any of the microphones is generated in a section other than the
chorus section by outputting the singing voice from the second microphone from the other
speaker. Since it mixes with performance data and makes it output from both the 1st speaker and
the 2nd speaker, when singing the solo part, the listener is normally It is possible to produce a
clean singing voice, and the singing voices from the first microphone and the second microphone
are output from separate speakers to the listener in the chorus section, so it is natural for the
listener It can be listened to in a realistic state, and it is possible to suitably produce a sense of
reality and a three-dimensional effect.

The chorus section identification means 22 acquires the lyrics drawing data of the duet song
from the lyric display control unit 19, and during the performance of the duet song, based on the
singing section data of the duet song specified in advance, along with the progress of the
performance. It is a program which acquires chorus section data while identifying whether the
timing currently being played is a chorus section or not.
[0014]
As chorus section data for identifying whether it is a chorus section or not, lyric rendering data
(including color change data, external character mark data, etc.) for expressing lyrics in
synchronization with digital performance based on performance data (note data) For example, as
shown in FIG. 2, in the duet song, the prelude part, the female part, the male part, the chorus part
(chorus section), the interplay part and the post performance part are specified, and usually the
female The drawn lyrics in the part, the male part, and the chorus part are changed in different
colors or marked with different types of external character marks.
Therefore, by configuring the chorus section identification means 22 so that the type of the song
section can be identified by the type of the color of the lyric display color and the type of the
extra character, if the lyric depiction data is used, It is possible to identify whether the timing
currently being played is a chorus section or not.
