Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a karaoke apparatus.

[0002]

2. Description of the Related Art Conventionally, when a user enjoys karaoke, he or she selects a song to be sung by referring to a song name guidebook attached to the karaoke device, and inputs the song number or the like to perform the selected karaoke song. It is like this. In recent years, the types of karaoke songs that can be selected in such a karaoke device have been diversifying from simple songs that can be sung by anyone to advanced songs that require professional-level technology. By the way, one of the criteria for judging the difficulty level of singing a karaoke song is the musical range of the song, which includes extremely high or low tones, or has a wide overall range. It can be said that there is.

[0003]

In the conventional karaoke apparatus, it is often unknown whether or not the musical range of a song is suitable for one's own musical range until the song is actually sung. As a result, when singing is driven only by the desire to sing a favorite song, it causes an unexpected breakdown in the middle of the singing due to a range problem, and it is embarrassing in the presence of the seated person or it is difficult to sing. Problems such as overcrowding can often occur.

An object of the present invention is to provide a karaoke device which allows a singer to select a song in consideration of his or her own musical range, and which is less likely to cause a breakdown in the musical range during singing.

[0005]

In order to solve the above-mentioned problems, the karaoke apparatus of the present invention is characterized by being provided with the following requirements. Musical sound data storage means: Stores musical sound data of a musical piece in association with musical range information, which is information related to the musical range (musical range) of the singing section of the musical composition. Singer range information designating means: Designates the content of the singer range information, which is information related to the singer's singable range (singer range). Performed music retrieval means: Retrieval of a musical composition in which the contents of the specified musical range information match the specified contents of the singer's musical range information under a predetermined condition. Karaoke playing means: The musical tone data of the retrieved musical piece is read from the musical tone data storage means to perform a karaoke performance.

According to the above configuration, the musical tone data of each musical piece to be played is stored in association with the musical tone range, and the predetermined condition is satisfied with respect to the content of the singer tone range information designated by the singer tone range information designating means. Under this condition, it is possible to extract and retrieve a musical piece to which the contents of the musical piece range information match. Therefore, the singer can select a song in consideration of his own range, and as described above, the range is not broken during singing.

Here, the musical tone range information may include information for specifying at least one of the highest note (the highest note of the song) and the lowest note (the lowest note of the song) of the singing portion of the performance song. In addition, the singer range information may include information that specifies at least one of the highest sound (singer highest sound) and the lowest sound (singer lowest sound) that the singer can sing. In this way, the singer specifies the highest note or the lowest note of his or her own, so that a musical piece having a range corresponding to the highest note or the lowest note is searched for, so that the above-mentioned problem is less likely to occur.

Next, the singer's tone range information designating means includes a voice inputting means for inputting the voice of the singer, a tone range analyzing means for performing a tone range analysis of the singer based on the inputted voice, and an analysis result thereof. Based on this, it can be configured to include a singer range information generating unit that generates singer range information. According to this configuration, the range information of the singer is generated based on the actual voice of the singer, so that the range of the singer can be grasped more accurately, and the above-described effect is further enhanced.

Here, it is more realistic that the highest or lowest tone of the singer is the highest or lowest tone that can be stably produced in time with the performance of the song without causing a problem in pitch. I can say. Therefore, in the above configuration, a guide sound generating means for generating a guide sound for guiding the voice input of the singer is provided, and the range analysis means is used to determine whether the pitch of the voice of the singer matches the guide sound. At least one of the highest note and the lowest note of the singer described above may be analyzed based on In this way, it is possible to search for a musical piece in the range more suitable for the singer without worrying about out-of-range. Guide sound generation means,
Specifically, as the guide sound, a scale that starts from a predetermined reference sound and rises or falls at predetermined intervals can be generated. In this case, the range analysis means sets the pitch when the pitch of the voice of the singer, which is input while being guided by the rising or falling scale, begins to deviate from the above scale, as the highest pitch or the lowest pitch of the singer. be able to. In other words, in many playing songs, it is necessary to produce the highest or lowest note of the song within a certain melody line, so by using the induced note as a scale, a more realistic range analysis can be performed. It will be possible.

[0010] Next, the performance music search means is specifically a performance music having a music highest pitch equal to or lower than the singer's highest pitch, and a music lowest pitch equal to or lower than the singer's lowest pitch. Can also be searched for at least one of the higher performed songs. In this case, if a music display means for displaying a list of the searched performance music pieces is provided, for example, when there are a plurality of performance music pieces having matching musical ranges under the above-mentioned conditions, these are displayed as a list. You can easily select the performance song.

The musical composition search means is a musical composition in which the highest pitch of the music is higher than the highest pitch of the singer by a predetermined pitch, and the lowest pitch of the music is performance lower than the lowest pitch of the singer by a predetermined pitch. At least one of the songs may be searched together. In this way, it is possible to search for a musical piece that is slightly out of range, and it is possible to broaden the range of musical piece selection. In this case, if the musical composition display means is configured to display the retrieved musical composition in association with at least one of the musical composition highest note and the musical composition lowest note, it is more convenient in selecting the musical composition in consideration of the musical range. Further, by providing a range changing means for moving the entire performance range of the music performed by the karaoke performance means to the high pitch side or the low pitch side by a predetermined pitch, the range of music selection can be further widened. .

Next, as shown in FIG. 4, the RAM 13 of the karaoke control unit 10 includes a song reservation memory 13a and a range data memory 13b (described later) for storing data such as song numbers input from the input unit 19. It is provided. Also, R
The following programs are stored in the OM 12. Musical performance program 12a: The musical tone data of the musical composition retrieved by the electronic quick sample 1 is read from the musical tone data storage unit 24 to perform the musical composition. It also manages the process of moving the pitch of the performance sound to the high pitch side or the low pitch side based on the input contents from the pitch change key 55 (FIG. 2). Lyrics output program 12b: Converts the lyrics data stored in the lyrics data storage unit 25 into a lyrics telop and outputs it to the monitor 7. Background video output program 12c: Reads the background video data stored in the background video data storage unit 26 and outputs it to the monitor 7. Range measurement program 12d: Controls the range measurement process of the singer.

The operation of the karaoke machine 9 will be described below with reference to a flow chart. First, in S1 of FIG.
Electronic quick sample 1 to select whether or not to measure the range of the singer
Using the input unit 45 (FIG. 2). When “Perform range measurement” is selected, a range measurement guide screen 48a as shown in FIG. 10A is displayed on the display unit 48. The singer will perform the voice input necessary for the range measurement from the microphone 5 according to the contents of the guide display. After that, the process proceeds to S2 and the range measurement process is performed. The details are shown in FIG.
First, in step S201, the first guidance sound data (that is, the reference sound data) is read from the guidance sound data storage unit 27, is sent to the musical tone synthesis unit 17, and the guidance sound based on the data is output from the speaker 6. At the same time, the voice waveform of the guidance sound from the musical tone synthesis unit 17 is sent to the pitch measurement unit 30. The singer, while listening to the guide sound, makes a sound with the same pitch as this sound toward the microphone 5.

Next, in S204 and S205, the voice data of the singer is filtered. FIG. 9 is a diagram showing characteristics of digital filter processing realized based on the pitch measurement program 35a. In this figure, the horizontal axis represents frequency and the vertical axis represents filter sensitivity, which is a curve having sensitivity peaks when the frequency values are F1, F2, and F3, respectively. These peak frequencies F1, F2, F
For example, 3 can set F2 based on the frequency of the induced sound waveform and use it as a reference frequency for pitch measurement, and F1 and F3 can be set as frequencies corresponding to lower and higher pitches, respectively. .

As the digital filter processing, it is preferable to perform band-pass processing by a known method such as a biquad filter. In this case, the input voice data is sequentially subjected to the filtering process in which the frequencies of the sensitivity peaks are the above three values F1, F2, and F3, respectively, and the square of the data output after the process is the measurement time c. Integration processing is performed as an integration section (S206). Then, the peak frequency of the filtering process that maximizes the integrated value is the frequency (pitch) closest to the frequency of the input voice. That is, in S207, it is determined which is the peak frequency of the filtering process that maximizes the integrated value. If it is F2, it is determined that the pitches match, and the process proceeds from S208 to S210. As the next guiding sound data, the guiding sound data which is one sound (or half tone) higher than the preceding guiding sound is read out, and the procedure goes to S202. After returning, the same processing is repeated. As a result, the guide sound becomes a scale that starts from the reference tone and rises by one tone (or half tone), and the singer will sequentially utter each tone in accordance with this rising scale. The guide sound data can be stored in the guide sound data storage unit 27 as digital voice waveform data. In this case, in addition to the musical sound synthesizer 17, it is necessary to provide a guide sound generating device for generating a guide sound based on the digital voice waveform data.

Then, in S207, it is judged that the pitch has begun to deviate when the above-mentioned integrated value becomes a value other than F2, and the process proceeds to S211, in which the guidance sound immediately before the pitch deviates (previous guidance sound). , Range data memory 13b as data of the highest sound of the singer (that is, singer range information)
(FIG. 4). On the other hand, when the pitch does not fall out to the last guiding sound, the last guiding sound is stored in the range data memory 13b as the data of the highest note of the singer. Note that if only the highest note is measured, the range measurement process ends here and returns, but if the lowest note is also measured, the lowest note measurement process continues following almost the same procedure as described above. The obtained lowest tone of the singer is similarly stored in the range data memory 13b. in this case,
The difference from the above processing is that the guide sound is a scale starting from the reference sound and descending by one sound (or semitone). In this way, the range measurement process is completed, and the display unit 48 displays
The result notification screen 48b for notifying the singer of the measurement result (Fig. 1
0 (b)) is displayed.

By increasing the number of filter processing routines having different peak frequencies, more pitch states can be measured and determined. Further, the coefficients of the digital filter can be stored in the ROM 35 of the pitch measuring section 30 as a table referred to by the pitch. In addition to the above, a method using a fast Fourier transform, a phase locked loop, or the like can be adopted as the pitch measuring method. In either case, the amount of calculation can be saved by measuring the pitch only in the vicinity of the reference frequency.

On the other hand, when "do not perform range measurement" is selected in S1, for example, the range input screen 48c shown in FIG. 12 is displayed, and the singer uses the input section 45 to select the highest sung song. The data of the sound or the lowest sound is input (S3). The input data is stored in the range data memory 13b as singer range information. Then, the process proceeds to S4, and it is selected whether or not to perform a music search using the music selection data (FIG. 10 (c) shows the search guide screen 48d). If "Search songs" is selected, S5
The process from S7 to S7 is performed, and the performance music is searched by sequentially inputting search data such as a singer name and a music name. FIG.
(A) and (b) show a display example of the search screen 48e in the case of performing a search based on the genre of the performance song or the release era.

After narrowing down the performance songs to some extent,
In S8, a selection is made as to whether or not the range is specified (FIG. 11C shows an example of the selection screen 48f). When the range designation is selected, whether the highest note 93a of the song is the same as the highest note of the singer by referring to the data of the highest note or the lowest note of the singer stored in the range data memory 13b (FIG. 4). Alternatively, a musical piece lower than that and a musical piece whose lowest note 93b is the same as or higher than the lowest note of the singer are searched (S9), and the searched musical pieces are shown in FIG.
Listed in the performance music list 48g shown in (S1)
0). The singer selects a desired performance piece with the cursor 48k (S11).

Here, the highest note of the song is 1 with respect to the highest note of the singer.
It is possible to perform processing so as to search for a musical piece that is higher by one to two notes and a musical piece whose lowest note is one to two notes lower than the lowest note of the singer. In this case, FIG.
When a search for a song in which the highest note or the lowest note is higher by 1 or 2 tones is specified on the range selection screen 48h shown in (a), the auxiliary performance song list 48j shown in (b) to (c) of the same figure.
A list of the corresponding performance songs is displayed. When selecting a music from the auxiliary performance music list 48j, S1 in FIG. 7 is selected.
4 to S16, the pitch change key 55 (FIG. 2) is used to shift the pitch of the performance note to the treble side or the bass side in order to adapt the highest note or the lowest note to the singer range. Input for If a song is selected in the auxiliary performance song list 48j,
The shift process of the corresponding pitch may be automatically executed.

In this way, the program proceeds to S17, and the song number of the selected song is stored in the song reservation memory 13a of the RAM 13 (FIG. 4). Then, when the music piece is reserved, the music performance program 12a is activated, and the first one of the music numbers stored in the music reservation memory 13a is read out, and the musical tone data, the lyrics data and the music data corresponding to the music number are read. The background video data is read out, and the music performance and lyrics are displayed.
Further, when the above-mentioned pitch shift is input, the performance sound is output in a state of being shifted by the above-mentioned pitch.

Then, in S18, if the next music selection is to be performed, the process proceeds to S19, and if the range designation is to be redone, S is performed.
If not 1, the process returns to S4 and the same process is repeated. On the other hand, if the song search is not performed in S4, the process proceeds to S12, and the normal song selection process using the song number or the like is performed, and the process proceeds to S14 through S13. Here, S13
In, the range data 93 of the selected musical piece is displayed on the display unit 48 or the like. The singer refers to this and S1
In 4, the pitch shift input described above can be performed.

The voice input for the range measurement processing is
Instead of performing according to the guidance sound, the singing person may sing along with the actual musical composition and measure the pitch for the singing to determine the highest or lowest pitch of the singer.
