Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1 and 2 are schematic diagrams of a lyrics display device according to an embodiment of the present invention. This lyrics display device is configured as an electronic musical instrument 100 which is a keyboard musical instrument as an example, and has a main body portion 30 and a neck portion 31. The body portion 30 has a first surface 30a, a second surface 30b, a third surface 30c, and a fourth surface 30d. The first surface 30a is a keyboard arrangement surface on which a keyboard portion KB including a plurality of keys is arranged. The second surface 30b is the back surface. Hooks 36 and 37 are provided on the second surface 30b. A strap (not shown) can be hung between the hooks 36 and 37, and the player usually hangs the strap on his shoulder to perform operations such as operating the keyboard portion KB. Therefore, when the player is on a shoulder, especially when the scale direction (key arrangement direction) of the keyboard portion KB is the left-right direction, the first surface 30a and the keyboard portion KB face the listener side, and the third surface 30c, the fourth surface 30c. The surfaces 30d face generally downward and upward, respectively. It should be noted that the electronic musical instrument 100 is designed so that the keyboard portion KB is played mainly by the right hand when it is used on the shoulder.

The neck portion 31 extends from the side portion of the main body portion 30. The neck portion 31 is provided with various operators such as a forward operator 34 and a return operator 35. A display unit 33 made of liquid crystal or the like is arranged on the fourth surface 30d of the body portion 30. The side view shapes of the main body portion 30 and the neck portion 31 are generally rectangular, but each of the four surfaces forming the rectangle does not have to be a flat surface, and may be a curved surface such as a convex surface.

The electronic musical instrument 100 is a musical instrument that can perform a singing simulation in response to an operation on a performance operator. Here, the singing voice simulation is to output a voice simulating a human voice by singing voice synthesis. White keys and black keys are arranged in the order of pitch of each key of the keyboard portion KB, and each key is associated with a different pitch. When playing the electronic musical instrument 100, the user presses a desired key on the keyboard portion KB. The electronic musical instrument 100 detects a key operated by the user and produces a singing sound having a pitch corresponding to the operated key. The order of the syllables of the singing sounds to be pronounced is predetermined.

FIG. 3 is a block diagram of the electronic musical instrument 100. The electronic musical instrument 100 includes a CPU (Central Processing Unit) 10, a timer 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a data storage unit 14, a performance operator 15, and other operations. A child 16, a parameter value setting operator 17, a display unit 33, a sound source 19, an effect circuit 20, a sound system 21, a communication I/F (Interface), and a bus 23.

The CPU 10 is a central processing unit that controls the entire electronic musical instrument 100. The timer 11 is a module that measures time. The ROM 12 is a non-volatile memory that stores a control program and various data. The RAM 13 is a volatile memory used as a work area of the CPU 10 and various buffers. The display unit 33 is a display module such as a liquid crystal display panel or an organic EL (Electro-Luminescence) panel. The display unit 33 displays the operating state of the electronic musical instrument 100, various setting screens, messages to the user, and the like.

The performance operator 15 is a module that mainly accepts a performance operation that specifies a pitch. In the present embodiment, the keyboard KB, the advance operator 34, and the return operator 35 are included in the performance operator 15. As an example, when the performance operator 15 is a keyboard, the performance operator 15 indicates note-on/note-off based on ON/OFF of a sensor corresponding to each key, key pressing strength (speed, velocity), and the like. Outputs performance information. This performance information may be in the form of a MIDI (musical instrument digital interface) message.

The other operator 16 is an operation module such as operation buttons and operation knobs for performing settings other than performance, such as settings related to the electronic musical instrument 100. The parameter value setting operator 17 is an operation module such as operation buttons and operation knobs for setting sound parameters. Examples of the parameter regarding the attribute of the singing sound include harmony (Harmonics), brightness (Brightness), resonance (Resonance), and gender factor (Gender Factor). Harmony is a parameter that sets the balance of the overtone components contained in the voice. Brightness is a parameter that sets the brightness of a voice, and gives a tone change. Resonance is a parameter that sets the tone color and strength of colored sounds. The sex factor is a parameter that sets the formant, and changes the thickness and texture of the voice to be feminine or masculine. The external storage device 3 is, for example, an external device connected to the electronic musical instrument 100, and is, for example, a device that stores audio data. The communication I/F 22 is a communication module that communicates with an external device. The bus 23 transfers data between the respective parts of the electronic musical instrument 100.

The data storage unit 14 stores singing data 14a (lyric data). The singing data 14a includes lyrics text data, a phoneme information database, and the like. The lyrics text data is data that describes the lyrics. In the lyrics text data, the lyrics of each song are described in syllable units. That is, the lyrics text data has character information in which the lyrics are divided into syllables, and this character information is also display information for displaying the lyrics corresponding to the syllables. Here, a syllable is a group of sounds output in response to one performance operation. The phonological information database is a database that stores voice segment data. The voice unit data is data indicating a waveform of voice, and includes, for example, spectrum data of a sample sequence of voice units as waveform data. Further, the voice unit data includes voice unit pitch data indicating the pitch of the waveform of the voice unit. The lyrics text data and the voice segment data may be managed by a database.

The sound source 19 is a module having a plurality of sound generation channels. One tone generation channel is assigned to the sound source 19 under the control of the CPU 10 in accordance with the performance of the user. When singing a singing sound, the sound source 19 reads out the voice unit data corresponding to the performance from the data storage unit 14 in the assigned sounding channel to generate singing sound data. The effect circuit 20 applies the acoustic effect designated by the parameter value setting operator 17 to the singing sound data generated by the sound source 19. The sound system 21 converts the singing sound data processed by the effect circuit 20 into an analog signal by a digital/analog converter. Then, the sound system 21 amplifies the singing sound converted into an analog signal and outputs it from a speaker or the like.

FIG. 4 is a diagram showing a main part of the display unit 33. The display unit 33 has a first main area 41, a second main area 42, a first sub area 43, and a second sub area 44 as display areas. The entire display area has a two-row (two-stage) structure, with the first main area 41 and the first sub-area 43 being the first row (upper row), and the second main area 42 and the second sub-area 44 being two rows. It is placed in the eye (lower). In each of the main areas 41 and 42, a plurality of display frames 45 (45-1, 45-2, 45-3... 45-13) which are a plurality of display units are continuously arranged in series in the longitudinal direction of the display unit 33. ing. Each of the sub areas 43 and 44 also has a display frame 46 (46-1, 46-2, 46-3) which is a plurality of display units. The plurality of display frames 45 are a first display unit group which is a continuous partial display unit group, and the plurality of display frames 46 are a second display unit group which do not belong to the first display unit group. .. The display frame 45 may display characters, and the display frame 46 may have a structure capable of displaying visual information such as an icon. The structure does not matter, and it is not essential that the display frame 46 be surrounded by a frame. With the display frame 45-1 at the left end of FIG. 4 as the head, the characters corresponding to the syllables are displayed in the order of pronunciation. The main areas 41 and 42 are mainly used for displaying lyrics. The sub-areas 43 and 44 are displays other than lyrics and are mainly used for status display.

FIG. 5 is a flowchart showing an example of the flow of processing when the electronic musical instrument 100 performs a performance. Here, a process when the user selects a performance song and plays the selected song will be described. Further, in order to simplify the description, a case will be described in which only a single sound is output even when a plurality of keys are simultaneously operated. In this case, of the pitches of the keys operated simultaneously, only the highest pitch may be processed, or only the lowest pitch may be processed. The processing described below is realized, for example, by the CPU 10 executing a program stored in the ROM 12 or the RAM 13 and functioning as a control unit that controls various configurations of the electronic musical instrument 100.

When the power is turned on, the CPU 10 waits until an operation for selecting a song to be played is accepted by the user (step S101). If there is no music selection operation even after a certain period of time, the CPU 10 may determine that the music set by default has been selected. Upon receiving the selection of the song, the CPU 10 reads the lyrics text data of the song data 14a of the selected song. Then, the CPU 10 sets the cursor position to the head syllable described in the lyrics text data (step S102). Here, the cursor is a virtual index indicating the position of the syllable to be generated next. Next, the CPU 10 determines whether or not the note-on based on the operation of the keyboard portion KB is detected (step S103). When the note-on is not detected, the CPU 10 determines whether or not the note-off is detected (step S107). On the other hand, when note-on is detected, that is, when a new key depression is detected, the CPU 10 stops outputting the sound if the sound is being output (step S104). Next, the CPU 10 executes an output sound generation process of generating a singing sound corresponding to the note-on (step S105).

This output sound generation process will be described. First, the CPU 10 reads the voice segment data (waveform data) of the syllable corresponding to the cursor position, and outputs the waveform sound indicated by the read voice segment data at the pitch corresponding to note-on. Specifically, the CPU 10 obtains the difference between the pitch indicated by the unit pitch data included in the voice unit data and the pitch corresponding to the operated key, and the waveform data is generated only at the frequency corresponding to this difference. The spectrum distribution shown is moved in the frequency axis direction. Accordingly, the electronic musical instrument 100 can output a singing sound at a pitch corresponding to the operated key. Next, the CPU 10 updates the cursor position (reading position) (step S106) and advances the process to step S107.

Here, the determination of the cursor position and the pronunciation of the singing sound according to the processes of steps S105 and S106 will be described using a specific example. First, the updating of the cursor position will be described. FIG. 6 is a diagram showing an example of lyrics text data. In the example of FIG. 6, the lyrics of five syllables c1 to c5 are described in the lyrics text data. Each character "ha", "ru", "yo", "ko", "i" represents one Japanese hiragana character, and each character corresponds to one syllable. The CPU 10 updates the cursor position in syllable units. For example, when the cursor is located at the syllable c3, the voice unit data corresponding to “yo” is read from the data storage unit 14 and the singing sound of “yo” is generated. When the pronunciation of "yo" ends, the CPU 10 moves the cursor position to the next syllable c4. In this way, the CPU 10 sequentially moves the cursor position to the next syllable in response to note-on.

Next, the pronunciation of the singing sound will be described. FIG. 7 is a diagram showing an example of types of speech unit data. The CPU 10 extracts the voice unit data corresponding to the syllable from the phoneme information database in order to pronounce the syllable corresponding to the cursor position. There are two types of phoneme segment data: phoneme chain data and stationary part data. The phoneme chain data is data indicating a phoneme when the pronunciation changes, such as “silence (#) to consonant”, “consonant to vowel”, “vowel to consonant (next syllable) or vowel”. .. The stationary part data is data indicating a voice segment when the pronunciation of a vowel continues. For example, when the cursor position is set to “ha (ha)” of the syllable c1, the sound source 19 outputs the voice chain data “#-h” corresponding to “silence→consonant h” and “consonant h→vowel a”. Of the voice chain data "ha" corresponding to "" and the stationary part data "a" corresponding to "vowel a" are selected. When the performance is started and the key depression is detected, the CPU 10 operates the singing sound based on the voice chain data “#-h”, the voice chain data “ha”, and the steady part data “a”. The pitch is output according to and the velocity is output according to the operation. In this way, the cursor position is determined and the singing sound is pronounced.

If note-off is detected in step S107 of FIG. 5, the CPU 10 stops outputting the sound if the sound is being output (step S108), and advances the process to step S110. On the other hand, if note-off is not detected, the CPU 10 advances the process to step S110. In step S110, the CPU 10 determines whether the performance has ended. CPU10 returns a process to step S103, when performance is not complete|finished by step S110. On the other hand, when the performance is ended, the CPU 10 stops the output of the sound if the sound is being output (step S111), and ends the processing shown in FIG. It should be noted that the CPU 10 determines whether or not the performance has ended, for example, whether or not the last syllable of the selected song has been sounded, or whether or not the operation for ending the performance has been performed by the other operator 16. It can be determined based on.

Next, the operation focusing on the lyrics display will be described. First, the lyrics text data included in the singing data 14a includes at least character information associated with each of a plurality of syllables corresponding to the selected song. The lyrics text data is data to be sung by the singing section (sound source 19, effect circuit 20, and sound system 21). The lyrics text data is divided into a plurality of sections in advance, and each of the divided sections is called a "phrase". A phrase is a unit that has a certain unit, and is separated by a meaning that a user can easily recognize, but the definition of a section is not limited to this. When the song is selected, the CPU 10 acquires the song in a state of being divided into a plurality of phrases. The phrase includes one or more syllables and character information corresponding to the syllables.

When the electronic musical instrument 100 is activated, the CPU 10 causes the first main area 41 (FIG. 4) of the display unit 33 to display the character information corresponding to the first phrase of the plurality of phrases corresponding to the selected song. At that time, the first character of the first phrase is displayed in the display frame 45-1 at the left end, and as many characters as can be displayed in the first main area 41 are displayed. As for the second phrase, as many characters as can be displayed in the second main area 42 are displayed. The keyboard portion KB plays a role as a progress instruction acquisition portion that acquires a singing instruction, and thus an instruction to advance the display of character information. In response to the acquisition of the singing instruction, the CPU 10 causes the singing section to sing the syllable to be singed next, and advances the display of the characters displayed in the first main area 41 according to the progress of the syllable. The stepping direction of the character display is the left direction in FIG. 4, and the character that could not be displayed first appears from the display frame 45 at the right end according to the progress of the singing. The cursor position indicates the syllable to be sung next, and indicates the syllable corresponding to the character displayed in the display frame 45-1 of the first main area 41.

Note that one character and one syllable do not necessarily correspond. For example, in "da" (da) having a dakuten, two characters "ta" (ta) and """ correspond to one syllable. Further, the lyrics may be English, and for example, when the lyrics are “septmber”, the syllables are “sep”, “tem”, and “ber”. Although "sep" is one syllable, three characters "s", "e", and "p" correspond to one syllable. Since the step of character display is in syllable units, in the case of "da", two characters are advanced by singing. As described above, the lyrics are not limited to Japanese and may be in another language.

FIG. 8 is a flowchart of the display process. Note that this processing is realized, for example, by the CPU 10 executing a program stored in the ROM 12 or the RAM 13 and functioning as a control unit that controls various components included in the electronic musical instrument 100. Further, the processing shown in FIG. 8 is executed in parallel with the processing shown in FIG. 5 after the power is turned on. In the process shown in FIG. 8, the CPU 10 functions as a state acquisition unit, a display control unit, a data acquisition unit, and a setting instruction acquisition unit. 9, FIG. 12, FIG. 12, FIG. 13, and FIG. 14 are diagrams showing display examples on the display unit 33. 11A, 11B, and 11C are diagrams showing display examples of subareas.

When the power is turned on, the CPU 10 causes the display unit 33 to display the startup screen shown in FIG. 9 (step S201). In this startup screen, for example, the manufacturer name is displayed in the first main area 41 and the first sub area 43, and the product name and the like are displayed in the second main area 42 and the second sub area 44. Then, the CPU 10 acquires the “predetermined state” regarding the electronic musical instrument 100 (step S202). During the acquisition of the state, the CPU 10 may switch the display unit 33 to a display indicating that it is being activated. Here, the predetermined state includes a state related to power supply, and includes, for example, whether the type of power source is a commercial power source or a battery, and further the state of the remaining battery level. Further, the predetermined state includes the setting state and the value of the key transpose, the number of the currently selected song, the state such as the presence or absence of internet connection, and the like. The predetermined state is not limited to these examples. It should be noted that the CPU 10 also acquires the singing data 14a of the selected song when acquiring the predetermined state, and further extracts a plurality of phrases corresponding to the selected song from the lyrics text data of the acquired singing data 14a. Multiple phrases are already ordered.

Next, the CPU 10 causes the display unit 33 to display a normal screen as shown in FIG. 10 (step S203). Specifically, the CPU 10 displays the lyrics in the main areas 41 and 42, and displays the information regarding the acquired state in the sub areas 43 and 44. In particular, regarding the lyrics display, the CPU 10 displays the characters of the first phrase of the extracted plurality of phrases in the first main area 41 as much as can be displayed from the beginning, and the characters of the second phrase are displayed in the second main. The area 42 is displayed as much as possible from the beginning. For example, as shown in FIG. 10, the CPU 10 displays the character string “dundant...” In the first main area 41 and the character string “aiueo...” In the second main area 42. Information about the selected song and the set tone color may be temporarily displayed during the transition from the display indicating the start-up to the normal screen display.

By the way, the CPU 10 may use at least one of the main areas 41 and 42 for displaying lyrics, and may use at least one of the sub areas 43 and 44 for displaying information related to a state (hereinafter, state information). As an example of the state information display, in FIG. 10, the icon indicates that the power supply state is battery and the charge state (remaining battery level) is fully charged. The electronic musical instrument 100 may have a singing voice synthesis mode and a musical instrument pronunciation mode. The display example of FIG. 10 assumes a singing voice synthesis mode. In the normal screen display in the musical instrument sounding mode, the CPU 10 may display information indicating the musical instrument tone color in the main areas 41, 42 instead of the lyrics.

Next, the CPU 10 determines whether or not the power is turned off (step S204), and if the power is turned off, various current information (state, set value, etc.) is stored in the nonvolatile memory (data storage unit 14). Etc.) (step S205), and then the processing shown in FIG. 8 ends. On the other hand, if the power is not turned off, the CPU 10 determines whether or not there is a change in the predetermined state (step S206). Then, the CPU 10 advances the processing to step S208 when there is no change in the predetermined state, while updating the display of the state information when there is a change in the predetermined state (step S207) and shifts the processing to step S208. Proceed.

Here, in step S207, the CPU 10 updates the display of the sub areas 43 and 44 based on the newly acquired information regarding the predetermined state. For example, when the CPU 10 obtains the status information indicating that the remaining battery level is low or the remaining battery level is low, the CPU 10 displays the remaining battery level in the sub-area 44 as shown in FIGS. 11A and 11B. Switch to the display. Alternatively, when the power source is switched from the battery to the commercial power source, the CPU 10 switches the display of the sub area 44 to the icon simulating the outlet, as shown in FIG. 11C. In these cases, the lyrics display in the main areas 41 and 42 is maintained as it is.

In step S208, the CPU 10 determines whether or not a change regarding the singing data 14a has been accepted. The change regarding the singing data 14a corresponds to, for example, a change in the singing position in the currently selected song or a change in the selected song itself. Then, when the change regarding the singing data 14a is not accepted, the CPU 10 determines whether or not an instruction for a predetermined setting is accepted (step S209). Here, the predetermined settings include, for example, settings related to sound generation (parameter setting changes such as effects and volume) and settings related to various functions (octave shift, mute, etc.). The predetermined settings also include firmware updates and the like. The predetermined setting is not limited to these examples.

If the CPU 10 has not received the instruction for the predetermined setting in step S209, the process returns to step S204, and if the instruction for the predetermined setting is received, the process proceeds to step S210. In step S210, the CPU 10 displays the setting screen using both the main area and the sub area. That is, the CPU 10 changes the display mode from the normal screen display to the setting screen display for displaying the information for the predetermined setting using both the first display unit group and the second display unit group in the display unit 33. Switch. For example, when the firmware update setting instruction is received, the CPU 10 causes the main area 41 and the sub area 43 to display character information indicating that the update mode is set, as shown in FIG. Character information indicating each version is displayed in the main area 42 and the sub area 44. When the effect change setting instruction is received, the CPU 10 displays the effect types and values before and after the change using the main areas 41 and 42 and the sub areas 43 and 44. In addition, when using the 1st line and the 2nd line in the display unit 33, there is no limitation in the mode of utilization of each line. For example, a mode in which setting change items are displayed on the first line and setting values are displayed on the second line can be considered.

In step S211, the CPU 10 reflects the content of the received setting instruction, and then determines whether or not there is an operation related to the setting instruction for a predetermined time while the setting screen display is displayed (step S21). S212). Then, if there is a new operation related to the setting instruction before the elapse of the predetermined time, the operation is accepted and the process returns to step S210. Note that the display of the setting screen display changes every moment by repeating steps S210 to S212, and the example shown in FIG. 12 is an example in the middle thereof. On the other hand, when the setting screen display is displayed and there is no operation related to the setting instruction for a predetermined time, the CPU 10 returns the display mode of the display unit 33 to the state immediately before switching to the setting screen display (step S213). Therefore, in the state where the information for the predetermined setting is displayed, if there is no operation related to the setting instruction for the predetermined time, the normal screen display immediately before is returned. Then, the process returns to step S204.

When the change regarding the singing data 14a is accepted in step S208, the CPU 10 determines whether or not the change in the selected song is accepted (step S214). Then, when the change of the selected song is not accepted, the accepted change is the song position of the currently selected song, so the CPU 10 updates the lyrics display in the main areas 41 and 42 (step S218). That is, the CPU 10 advances the display of the phrase in the first main area 41 by one syllable. Specifically, the CPU 10 deletes the character corresponding to the leftmost one syllable of the first main area 41, and fills the character string to the left by the deleted number. By advancing the phrase display by one syllable, the syllable corresponding to the character newly displayed in the display frame 45-1 becomes the next singing target. For example, in the display state shown in FIG. 10, when one of the keys of the keyboard portion KB is pressed to sing the leading “da” syllable in the first main area 41, the syllable corresponding to the next syllable “N” is displayed at the top (FIG. 13). Here, the display of the second main area 42 does not change (does not step). Therefore, step S218 corresponds to steps S105 and S106 of FIG. The display may be moved forward in phrase units by operating the advance operator 34. Further, the display may be moved backward in phrase units by operating the return operator 35. When adopting the carry-up and carry-down for each phrase, a process of updating the cursor position may be added immediately before step S110 of FIG. 5 correspondingly. After that, the process proceeds to step S209.

When the change of the selected song is accepted in step S214, the CPU 10 causes one or both of the main areas 41 and 42 in the display unit 33 to display a screen for changing the song (step S215), and gives a change instruction. The changed contents are reflected in accordance with (step S216). At this time, the status display is maintained in the sub areas 43 and 44. For example, as shown in FIG. 14, the titles of the songs before and after the change are displayed in the first main area 41, and the data is replaced. After that, if there is no operation regarding the selected song for a predetermined time, the CPU 10 switches the display mode to the normal screen display in which the lyrics of the changed selected song are displayed in the main areas 41 and 42 in step S217. Therefore, in the normal screen display as shown in FIG. 10, the content updated to the lyrics according to the selected song is displayed on the display unit 33. After that, the process proceeds to step S209.

According to the present embodiment, CPU 10 causes the first display section group (display frame 45 group of main areas 41, 42) in display unit 33 to display the character information included in acquired song data 14a. At the same time, the acquired state is displayed on the second display unit group (the display frame 46 group of the sub areas 43 and 44). As a result, the lyrics and the state can be visually recognized without complicated operations.

Further, when the instruction of the predetermined setting is acquired, information for the predetermined setting is displayed using both the first display unit group and the second display unit group. A wide range of display units 33 can be used.

Further, when the operation related to the instruction for the predetermined setting is not continued for the predetermined time while the information for the predetermined setting is displayed, the display mode of the display unit 33 is changed to the normal screen display state immediately before the switching. Since the setting is returned, it is possible to return to the lyrics and the status display without any operation when the setting is completed.

Although the entire display area of the display unit 33 has a two-row (two-stage) configuration, it may have three or more rows. Further, although the main areas are arranged side by side vertically, the arrangement relationship is not limited to the example, and they may be arranged side by side.

The acquisition source of the singing data 14a is not limited to the storage unit, and an external device via the communication I/F 22 may be acquired. The electronic musical instrument 100 may be acquired by the CPU 10 by being edited or created by the user.
