DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a karaoke device, and particularly to a karaoke device that can adjust the pitch of music to be performed according to the singer.

[Prior Art] Traditionally, musical sound information has been transmitted to electronic musical instruments such as synthesizers, electronic pianos, and rhythm machines, and accompaniment played by the electronic musical instruments is automatically output, and images output from laser disk devices. A karaoke machine is well known in which the user sings while looking at the lyrics superimposed on the karaoke. Furthermore, some karaoke machines have all the videos, performances, and lyrics stored on a laser disc.

In this type of karaoke apparatus, the pitch of the karaoke music played is out of tune with the vocal range of the singer, which often makes it very difficult for the singer to sing.

In this case, the people around them would also have to listen to the singing, which was extremely annoying.

For this reason, some conventional karaoke machines are equipped with a function that allows a person to change the pitch of the music played each time using a volume knob or the like.

[Problems to be Solved by the Invention] However, with the above-mentioned conventional karaoke device, in order to change the pitch of the performance music to the vocal range of the singer, it is necessary for a person with pitch sense to adjust the pitch volume. This adjustment was extremely difficult for those without it.

Furthermore, in the conventional apparatus described above, it is necessary to readjust the pitch volume in accordance with the vocal range of each singer, which is extremely complicated to handle.

The present invention has been made in view of the above problems, and an object thereof is to provide a karaoke apparatus that can automatically adjust the pitch of performance music to match the singer's vocal range.

[Means for Solving the Problem] In order to achieve the above object, the present invention provides a karaoke device that reproduces performance music and emits the singer's voice from a speaker together with the performance music. a voice input means for inputting at least one voice; a range analysis means for detecting the vocal range of the singer from the input voice; and a pitch adjustment means for setting the pitch of the performance music according to the detected vocal range of the singer; It is characterized by having the following.

[Function] According to the above configuration, when the singer inputs at least one voice in the low range or the high range in advance, the singer's range is automatically detected from the input voice, and the accompaniment is performed. The pitch of the performance music will be automatically set according to the detected vocal range of the singer.

In particular, according to the present invention, by adjusting the pitch of the performance music so that the main melody of the performance music is included in the detected vocal range of the singer, the singer can comfortably sing in his or her own vocal range.

[Example] Hereinafter, an example of the present invention will be specifically described with reference to the drawings.

FIG. 1 shows the configuration of a karaoke apparatus according to an embodiment, and a karaoke apparatus main body 10 has a microphone 12.
．． A speaker 14 and a CRT 16 are connected.

The karaoke device main body 10 is also provided with a keyboard unit 20, which has operation keys for specifying and reserving songs, and further sets the operation mode to the singer's vocal range registration mode. A range registration key is provided.

A central control section 22 is connected to the keyboard section 20, and an ID input section 24 and an ID memo 9 section 26 are further connected to the central control section 22.

The ID input section 24 is for inputting the singer's ID code when setting the range registration mode.
The code is set in the ID memo 9 section 26 by the central control section 22.

Further, a program memory section 28 in which various programs are written, and a frequency analysis section 30 are connected to the central control section 22 . The program memory section 28 stores an auxiliary program for detecting the vocal range of the singer and a pitch adjustment program for setting the pitch of the performance music to be played according to the detected pitch range.

After setting the ID code, the central control section 22 drives the sound source section 32 according to the auxiliary program set in the program memory section 28, and outputs an accompaniment sound for range detection from the speaker 14 via the mixing amplifier 34.

The singer inputs a voice matched to each accompaniment sound into the microphone 12, and the input voice is input into the frequency analysis section 30.

The frequency analysis section 30 functions as a range analysis means for detecting the singer's range from the input audio signal, and specifically, as shown in FIG.・The area where the voice level exceeds the reference level is detected as the vocal range of the singer.

The central control unit 22 stores the detected vocal range of the singer in the ID memo 9 section 26 in association with the ID code thereof.

The karaoke apparatus main body 10 also includes a musical tone information storage medium 1 that stores musical tone information and lyric information of a large number of songs.
2 is provided. The information stored in the musical tone information storage medium 12 is digital data, and is generally MID.
I (Musical Instrument Digi
tal Interface) (rM ID
IJ is a trademark) information. This MID
I information is internationally standardized information, including pitch, timbre,
This is information indicating volume, etc.

The central control section 22 reads out the data of the reserved music, displays the lyrics information as an image on the CRT 16, and outputs musical tone information to the sound source section 32.

In this case, the central control section 22 also functions as a musical tone adjustment means according to the pitch adjustment program stored in the program memory section 28, and when the vocal range of the singer is registered in the ID memo 9 section 26, In this step, the pitch of the musical tone information is automatically adjusted so that the main melody of the musical tone information is included in the registered musical range, and the sound source section 32 outputs it.

In other words, if the main melody of the musical sound information is higher than the singer's range, the main melody of the musical sound information is converted to be, for example, 2 or 3 degrees lower.On the contrary, if the main melody is lower,
The pitch of the main melody is converted to be 2 or 3 degrees higher, for example, and outputted to the sound source section 32.

The sound source section 32 is composed of a synthesizer, and has a MIDI
Based on the musical tone information input as information, a musical tone reproduction signal for karaoke accompaniment is outputted to the mixing amplifier 34.

The characteristic operation of the present invention by the karaoke apparatus having the above configuration will be explained based on the flowchart shown in FIG.

First, on the keyboard section 20, specify the song number of the song you want to sing, set the range registration mode (Sl), and enter the ID
The singer's ID code is input from the input section 44 (S2).

Then, the speaker 14 outputs high-pitched sounds starting from the pitch of "c" as accompaniment sounds for voice analysis, and the singer sequentially inputs sounds with the same pitch as each accompaniment sound from the microphone 12 (S3). At this time, the treble limit range of the singer is calculated from the input audio signal and stored in the ID memo 9 section 26 (S5).

Next, the speaker 14 outputs low notes in order from the height of "C" as accompaniment sounds for range analysis, and the singer inputs sounds with the same pitch as each accompaniment note from the microphone 12 (
S5). At this time, the singer's bass limit range is analyzed from the input audio signal and stored in the ID memo 9 section 26 (
S6).

Next, the central control unit 22 reads the musical tone information specified by the song number from the musical tone information storage medium 36, and adjusts the pitch so that the main melody of the musical tone information is included in the detected vocal range of the singer. The code is determined (S7), and the analysis result is displayed on the display unit 40 as shown in FIG.
S8).

Then, the read musical tone information is converted by the determined pitch and output to the sound source section 32, and the speaker 14 outputs an accompaniment that matches the vocal range of the singer.

In this embodiment, since the vocal range of the singer is registered together with the ID code in the ID memo 9 section 26, once the singer's own vocal range is registered, there is no need for a subsequent voice input operation for detecting the vocal range.
