BACKGROUND OF THE INVENTION
The present invention relates to a karaoke apparatus used in, for example, a karaoke box, and more particularly to a pitch recognition support function when singing.
[0002]
[Prior art]
2. Description of the Related Art A music playback device that outputs a desired performance song selected and input from a plurality of performance songs stored in advance in a predetermined storage device is known. As one aspect of such a music playback device, there is a karaoke device used in a karaoke box or the like. According to this karaoke device, a karaoke performance song selected by a predetermined input operation is output from a plurality of karaoke performance songs stored in advance in a storage device, and the lyrics character image of the karaoke performance song is synchronized with the output. Karaoke performance of a desired song can be enjoyed by displaying on the screen.
[0003]
By the way, generally, a song has a prelude (intro) as an introduction before the singing part (main performance) is started. On the other hand, there are not many such preludes, but there are many songs that are suddenly started from the singing part and very short songs that have preludes. In a karaoke performance of a song that does not have a sufficiently long prelude part, there is a problem that the performance of the singing part starts while the user is preparing to sing. Therefore, a karaoke apparatus having a standby function for singing has been developed. For example, it is a karaoke apparatus described in Patent Document 1. According to this karaoke device, when a karaoke performance is performed for a song that does not have a sufficiently long prelude section, the user is delayed by waiting without starting the performance of the singing section until a predetermined input operation is performed. You can sing without.

[0005]
[Problems to be solved by the invention]
However, when enjoying the karaoke performance of a song that does not have a sufficient length of the prelude described above, there is a problem that it is difficult for the user to recognize the pitch of the singing because the prelude does not exist. Therefore, when editing such a song as a karaoke performance, for example, as conceptually shown in FIG. 9, an original intro that does not exist in the original song is created and added in front of the singing section, or a singing at the time of karaoke performance Measures such as displaying a chord name representing the pitch on the screen have been taken prior to the output. However, many of the original intros do not match the atmosphere of the original music and tend to give the user a sense of incongruity, and because they are unfamiliar phrases, they have little effect of recognizing the pitch. Further, the code name cannot be understood by a user who does not have specialized music knowledge. That is, the present situation is that a karaoke apparatus that allows a user to appropriately recognize a pitch when singing a karaoke performance piece that does not have a sufficiently long predecessor has not yet been developed.
[0006]
The present invention has been made in the background of the above circumstances, and the purpose of the present invention is to recognize the pitch suitably for the user when singing a karaoke performance piece that does not have a sufficiently long prelude. It is in providing the karaoke apparatus which can be made.

In the performance data of FIG. 5, setting processing for the synthesizer 40 such as “PROGRAM” and “VOLUME” described above is executed at “STP: 2341” and “STP: 2342” which are the start points of the prelude data. This is based on the assumption that “STP: 2341-3300” is extracted and supplied to the synthesizer 40 as it is. As another configuration of the prelude data, there is no need for the synthesizer 40 such as “PROGRAM” and “VOLUME” described above at the start point. That is, at the start of the prelude, the settings for the synthesizer 40 are read at “STP: 1” and “STP: 2”, which are the start points of the performance data, and then the prelude is output by executing processing from the start point of the prelude data. It is also possible to adopt a configuration that
[0027]
The timing display means 60 displays an image representing the timing at which the output of the karaoke performance song is started prior to the output of the karaoke performance song for which the determination by the prelude part presence / absence determination means 54 is denied. FIG. 6 is an example of a video showing the timing when the output of the karaoke performance music displayed on the image display device 12 is started. (A) is two seconds before the output is started, and (b) is the output. One second before the start, (c) shows immediately before the output is started. The timing at which the output of the karaoke performance is started is represented by the movement of the movement mark (yellow line) 62, for example. First, as shown in FIG. 6A, the movement mark 62 displayed on the upper left side of the screen (hereinafter, omitted from the screen) is moved toward the right at a constant speed and approaches the right end to some extent. After flying to the center left, as shown in FIG. 6B, it is moved to the right again at a constant speed. Then, when approaching the right end to some extent, as shown in FIG. 6 (c), it is skipped to the head of the lyric character image and the movement mark 62 is erased, and at the same time, the output of the karaoke performance music is started.

In S10, after a part of the music information which is the content of the karaoke performance music is extracted as the prelude information based on the prelude designation information stored in the prelude designation database of the hard disk 32 and stored in the RAM 30 or the like, In S11 corresponding to the prelude output means 58, S1 is transmitted via the synthesizer 40, the amplifier mixer 18 and the microphone 22. Prelude is output based on the prelude information extracted in. In S12, it is determined whether or not 6 seconds or more have elapsed since the title image was displayed on the image display device 12. While the determination of S12 is denied, the process waits by repeatedly executing the determination of S12. However, when the determination of S12 is affirmed, the above-described operation is performed in S13 corresponding to the timing display means 60. 6 seconds or more have elapsed since the title image was displayed on the image display device 12 in S14 after the video (singing line) indicating the timing at which the output of the karaoke performance song is started as shown in FIG. It is determined whether or not. While the determination of S14 is denied, the process is kept waiting by repeatedly executing the determination of S14. However, when the determination of S14 is affirmed, the above-described S7 and subsequent steps are executed again.
[0031]
If the determination in S15 is negative, that is, if it is determined not to be the end of the karaoke performance, it is determined in S19 whether or not song information or the like has been transferred via the communication line 44 and the terminal adapter 34. If the determination in S15 is affirmative, that is, if it is determined that the end of the karaoke performance, it is determined in S16 that the selected song number of the karaoke performance song that has been completed is recorded as the performance record in the hard disk. After being stored in 32, in S17, it is determined whether or not a reserved song is stored in the RAM 30 or the like. If the determination in S17 is affirmative, the above-described S5 and subsequent steps are executed again. If the determination in S17 is negative, the display of new music information and the BGM performance are executed in S18. In S19, it is determined whether or not music information has been transferred via the communication line 44 and the terminal adapter 34. If the determination in S19 is negative, it is determined in S21 whether or not a karaoke performance is being performed, but if the determination in S19 is affirmative, the transferred music information etc. in S20. Is stored in the song database of the hard disk 32, etc., it is determined in S21 whether or not karaoke is being performed. If the determination in S21 is affirmative, the routine is terminated accordingly. If the determination in S21 is negative, it is determined in S22 whether predetermined inter-song information is being displayed. To be judged. If the determination in S22 is negative, the above-described S18 and subsequent steps are executed again. However, if the determination in S22 is affirmative, the routine is terminated accordingly.
[0032]

[0034]
Moreover, since the predecessor designation information designates a part of the chorus of the karaoke performance song as the prelude information, a part of the chorus that is a characteristic phrase of each karaoke performance song is extracted as the prelude information. In this way, there is an advantage that the user can more suitably recognize the pitch.
[0035]
Further, since the predecessor designation information is included in the song information of the karaoke performance song together with the music information and lyrics information which are the contents of the karaoke performance song, the prelude designation information is leaked when the karaoke performance song is output. When reading out a karaoke performance song that does not have the predetermined predecessor having a sufficient length, it is possible to reliably extract a part of the karaoke performance song and output it as a prelude. .
[0036]
Further, prior to the output of the karaoke performance song for which the determination by the predecessor part presence / absence determination means 54 is denied, a timing display means 60 (S13) for displaying an image representing the timing at which the output of the karaoke performance song is started. Therefore, there is an advantage that the user can sing without delay when singing a karaoke performance song that does not have the predetermined predecessor having a sufficient length.
[0037]
In addition, since the user can select whether or not to use the support by the singing support means 50 by a predetermined mode setting operation, when the user wishes to enjoy karaoke performance like the original music. Has an advantage that no support is performed by turning off the singing support mode.

For the karaoke performance piece that continues from “No. 1 → Interlude → No. 2 →...”, The end of No. 1 or the part corresponding to the interlude may be designated as prelude information. In this way, since No. 1 and No. 2 are generally the same phrase, the phrase corresponding to the last or interlude of No. 1 is output as a prelude, so that the subsequent phrase, that is, the singing phrase, is output. There is an advantage that it is easy to recall and allows the user to more suitably recognize the pitch.
[0040]
In the embodiment described above, the predecessor presence / absence determining means 54 has a predecessor flag as “ZF: 1” as the predecessor presence / absence information of the karaoke performance song stored in the predecessor designation database of the hard disk 32 For example, the time from the first step showing the music information output process in the performance information as shown in FIG. 5 to the first step showing the lyrics information output process is calculated. Then, it may be determined whether or not the time is a predetermined length or more.
[0041]
In the above-described embodiment, the prelude designation information is included in the song information of the karaoke performance song together with the music information and the lyric information which are the contents of the karaoke performance song, but is independent of the song information. It may be stored in the predecessor designation database of the hard disk 32 together with the music selection number.
