Hereinafter, an embodiment of a karaoke apparatus according to the present invention will be described with reference to the drawings.
FIG. 1 is an external view of a remote control device 1 of a karaoke system in the embodiment. As shown in FIG. 1, the remote control device 1 is provided with a switch unit 2 and an LCD display unit 3 which is a liquid crystal display. The switch unit 2 includes various switches necessary for karaoke performance in addition to the power switch, such as a song name switch 2a for searching for a song, a start switch 2b for starting performance, an icon of the LCD display unit 3, and the like. A cursor switch 2c for selecting and determining a character, a so-called numeric keypad switch 2d for inputting characters, numbers and symbols, a section specifying switch 2e for specifying a section of a song (details will be described later), from the current state to the previous state A return switch 2f for returning, a stop switch 2g for stopping performance, a switch for setting a volume, a switch for setting a tempo, a switch for setting a key, and the like are provided. The LCD display unit 3 displays a song name, lyrics, and others related to karaoke performance. Detailed display contents will be described later.

  FIG. 2 is a block diagram showing a configuration of the karaoke system in the embodiment. This karaoke system is configured by combining the remote control device 1 of FIG. 1 with a large monitor device such as a television receiver and a sound system having a speaker. The remote control device 1, the monitor device, and the sound system transmit and receive data and commands by short-range wireless communication such as infrared communication, FM radio wave communication, and Bluetooth (registered trademark) communication. That is, the image displayed on the LCD display unit 3 of the remote control device 1 is simultaneously displayed on the monitor device. However, here, in order to simplify the description, the LCD display unit 3 is representatively used as the display means of the karaoke system.

  2, in addition to the switch unit 2 and the display unit 3 shown in FIG. 16, the sound source unit 17, the microphone amplifier 18, and the network interface 19 are connected, and the entire karaoke system is controlled while exchanging data and commands with these units.

  The ROM 14 is a karaoke information processing program executed by the CPU 11 and other control programs, initial data, song name data, accompaniment song data and lyrics data corresponding to each song, model data by speech synthesis, and background. Stores screen data. The RAM 13 temporarily stores data processed by the CPU 11. In response to an instruction from the CPU 11, the video processing unit 15 combines the searched singer name, song name, lyric data, and background screen data and sends the synthesized data to the display unit 3. The microphone amplifier 18 amplifies the voice signal of the singer input from a microphone (not shown). The audio processing unit 16 converts the audio signal input from the microphone amplifier 18 from analog to digital. The RAM 13 temporarily stores the voice data of the singer converted to digital and has various registers and flags necessary for karaoke information processing executed by the CPU 11. The sound source unit 17 corresponds to the sound system described above, and converts accompaniment music data and model audio data or audio data in the RAM 13 from digital to analog in accordance with instructions from the CPU 11, and performs filter processing, amplification processing, and the like. Pronunciation from the speaker. The network interface 19 receives, for example, MIDI format music data from a network such as the Internet.

  Although not shown in the figure, an analog audio signal input from a microphone and amplified by the microphone amplifier 18 is directly emitted from a speaker. That is, the voice signal of the singer is recorded as digital voice data, and at the same time, the singer's voice signal is sounded from the speaker together with the musical tone signal corresponding to the read accompaniment data. When a television receiver is used as a large monitor device, an analog audio signal and musical sound signal may be modulated with a radio signal and transmitted.

3 to 10 are diagrams showing screens in the karaoke progress support mode displayed on the display unit 3. 3 is an initial screen in the progress support mode, FIG. 4 is a real-time evaluation screen during karaoke performance, FIG. 5 is an overall evaluation screen when the song is finished, and FIGS. 6 to 10 will be described later.
11 and 12 are diagrams showing the format of karaoke song data stored in the ROM 14 or song data received from a network such as the Internet via the network interface 19 and stored in the RAM 13. In FIG. 11, each of a plurality of songs (0) to songs (N) is composed of accompaniment data and model data. The accompaniment data of each song is divided into a plurality of sections (0) to (M), and lyrics data, time data, and accompaniment event data are stored according to addresses in each section. As shown in FIG. 12, the model data of each song stores time data and singing event data by voice synthesis according to addresses. In addition, this model data is not limited to the singing data by voice synthesis, and may be constituted by, for example, singing data obtained by PCM recording the voice sung by a professional singer.

  FIGS. 13 to 21 are flowcharts of a main routine of karaoke information processing executed by the CPU 11. FIGS. 22 and 23 are executed in response to an interrupt input from a timer (not shown) at regular intervals. 5 is a flowchart of timer interrupt 1 and timer interrupt 2. The operation of karaoke information processing in the embodiment will be described based on these flowcharts, the karaoke screens of FIGS. 3 to 10, and the song data of FIGS. 11 and 12.

  In FIG. 13, initialization of the audio data area, register, flag, etc. in RAM 13, initialization for prohibiting timer interrupt 1 and timer interrupt 2 is performed (step SA1), and a song selection screen (not shown) is displayed (step S1). Step SA2). On this song selection screen, a message such as “Please input the song name or singer name” is displayed to prompt the user to operate the song name switch 2a or singer name switch in the remote control device 1 of FIG. One or more music titles are displayed according to the user's switch operation. If there are a plurality of song titles, a message prompting the user to operate the cursor switch 2c or the numeric keypad switch 2d is displayed. When one song name is selected by the user's switch operation, song selection processing is performed (step SA3), and the song selection number is set in the register n (step SA4). That is, the music (n) corresponding to the number of the register n is retrieved from the music stored in the ROM 14 or RAM 13 and designated.

  Next, it is determined whether or not the start switch 2b is turned on (step SA5). The start switch 2b is a momentary switch. When this switch is turned on, the accompaniment data flag STF1 and the model data flag STF2 are set to "1" (step SA6). Further, register KUKAN1 for designating the accompaniment data section is set to “0 (first section)”, and register KUKAN2 for designating the model data section is set to “0 (first section)” (step SA7). Next, a background screen is displayed (step SA8), and the address of the head position of KUKAN1 (0) is designated by the accompaniment data of the song (n) (step SA9).

  Next, the process proceeds to the flowchart of FIG. 14, and the lyric data read from the address of the head position of KUKAN1 (0) is superimposed on the background screen and displayed as shown in FIG. 3 (step SA10). Thereafter, the address is incremented to read the next data (step SA11), and the read time data is stored in the register T1 (step SA12). Further, the address of the head position of KUKAN2 (0) is specified by the model data of the music piece (n) (step SA13), and the time data read from the address is stored in the register T2 (step SA14). Then, the prohibition of the timer interrupt 1 is canceled (step SA15). Most of the karaoke songs do not start suddenly, and there is an intro part of the accompaniment first, so the first time data of the model data is time data including at least the length of this intro part. Yes. That is, the accompaniment data time and the model data time are independent of each other, and therefore, the data read time is managed by the two types of registers T1 and T2.

  By canceling the prohibition of the timer interrupt 1, the timer interrupt 1 shown in FIG. 22 is executed every time a predetermined time elapses. That is, the value of the time data of T2 is decremented (step SB1), and the value of the time data of T1 is decremented (step SB2). Further, in order to guide the utterance timing, a color change process for displaying lyrics on the screen of the display unit 3 is performed (step SB3). Furthermore, the audio data input from the microphone, amplified by the microphone amplifier 18 and converted from analog to digital by the audio processing unit 16 is captured (step SB4), and the pitch (pitch) and volume of the audio data are detected. (Step SB5), the voice data is stored in the area of the RAM 13 together with the section number of KUKAN1 (step SB6). In this case, the audio data is stored while the address of the RAM 13 is incremented at regular intervals. After step SB6, the process returns to the main routine.

  In the flowchart of FIG. 15, it is determined whether or not the STF is “1 (accompaniment performance)” (step SA16). Since STF1 is set to “1” in step SA6 in FIG. 13, it is determined whether or not the value of T1 has reached “0” (step SA17). When the value of T1 reaches “0”, the address is incremented and the next data is read (step SA18). Then, it is determined whether or not the accompaniment data of the designated section has ended (step SA19). If the accompaniment data of the section has not ended, it is determined whether the read data is an event or a time. (Step SA20). If the read data is an event, it is sent to the sound source unit 17 (step SA21). On the other hand, if the read data is time, it is stored in the register T1 (step SA22).

  After the read event data is sent to the sound source unit 17, the address is incremented and the process proceeds to step SA18 to read the next data. On the other hand, after the read time data is stored in T1, the process proceeds to step SA5 in FIG. 13 to determine whether or not the start switch is turned on. When the start switch is not turned on, the process proceeds to the flowchart of FIG. 15 again, and when the value of T1 reaches “0”, the address is incremented and the next data is read. Therefore, as long as the start switch is not turned on and the data in the designated section is not completed, the loop of step SA5, step SA18 to step SA20, step SA21 or step SA22 is repeatedly executed to accompany the designated section. The data is sent to the sound source unit 17 to generate sound from the speaker.

  In step SA19 in FIG. 15, when the data of the currently designated section is completed, the value of the register KUKAN1 is incremented to designate the next section (step SA23). At this time, it is determined whether or not the incremented KUKAN1 value has become larger than the value M of the last section, that is, whether or not the musical sound of the accompaniment in that section has ended (step SA24). If the value of KUKAN1 is within the value M of the last section, the address of the new KUKAN1 head position is specified by the model data of the song (n) (step SA25), and the lyrics data read from that address To rewrite the display screen (step SA26). After this, unless the start switch is turned on and the data of the designated section is not completed, the loop of step SA5, step SA18 to step SA20, step SA21 or step SA22 is repeatedly executed to designate the designated section. The accompaniment data is sent to the sound source unit 17 to generate sound from the speaker.

  If the value of T1 has not reached “0” in step SA17 in FIG. 15, the process proceeds to the flowchart in FIG. 16 to determine whether STF2 is “1 (singing)” (step S17). SA28), since STF2 is set to “1” in step SA6 of FIG. 13, it is determined whether or not the value of register T2 has reached “0” (step SA29). When the value of T2 reaches “0”, the address of the model data is incremented and the next data is read (step SA30).

  When the address is incremented and the next data is read out in step SA30, it is determined whether or not the data in the currently designated section has been completed (step SA31). If the data in the section has not ended, it is determined whether the read data is an event, that is, an example data event or time data (step SA32). If the read data is an event, the pitch and volume of the event of the model data are extracted (step SA33). Next, a comparison process is performed between the pitch and volume of the audio captured from the microphone in step SB4 of the timer interrupt 1 in FIG. 22, detected in step SB5, and stored in the RAM 13 in step SB6 (step SA34).

  Next, as a result of comparing the pitch and volume of the model data with the pitch and volume of the sound taken in from the microphone, it is determined whether or not the deviation of the pitch and volume exceeds a predetermined value (step SA35). If the deviation exceeds a predetermined value, a warning display (NG) is displayed on the screen as shown in FIG. 4 (step SA36), and if the deviation is less than the predetermined value, a warning display (if displayed) Is turned off (step SA37). After the warning display or the warning display is turned off, the volume and pitch deviation are stored in the area of the RAM 13 together with the value of KUKAN1 (step SA38). Thereafter, the process proceeds to step SA30 to read the next data.

  When the read data is determined to be time in step SA32, the time data is stored in the register T2 (step SA39). Next, the process proceeds to step SA5 in FIG. 13 to determine whether or not the start switch 2b is turned on. If this switch is not turned on, the process proceeds to the flowchart in FIG. When the value does not reach “0”, the process proceeds to the flowchart of FIG. 16 and it is determined that the STF 2 is “1”. Therefore, it is determined whether or not the value of T2 has reached “0” in step SA29 of FIG. 16 by the processing of timer interrupt 1 of FIG.

  When the value of T2 reaches “0”, the next event data is read out in step SA30, and the processes in steps SA32 to SA38 are repeated unless the data in the currently specified section is completed. When the read data is time, the process proceeds to step SA5 in FIG. 13, step SA16 in FIG. 15, step SA28 in FIG. 15, and step SA29 in order, and when the value of T2 reaches “0”, Based on the read event data, while repeating the processing of step SA32 to step SA38, the pitch and volume deviation between the voice data and the model data captured from the microphone is displayed in real time and stored in the pitch and volume RAM 13 of the voice data. .

  In step SA31 of FIG. 16, when the data of the currently designated section is completed, the value of KUKAN2 is incremented to designate the next section (step SA40). At this time, it is determined whether or not the incremented KUKAN2 value exceeds the value M of the last section (step SA41). If the value of KUKAN2 does not exceed M, the address of the start position of the new KUKAN2 is designated by the model data of the song (n) (step SA42), and the data at that address is discriminated in step SA32. Since the data at the head position of KUKAN2 is an event, the processing from step SA33 to step SA38 is repeated.

  In step SA41 in FIG. 16, when the value of KUKAN1 becomes larger than the value M of the last section, that is, when the lyric portion of the song ends, “2 (end of lyric)” is set in STF2 ( Step SA43). Then, the process proceeds to step SA5 in FIG. 13 to determine whether or not the start switch 2b is turned on. If the start switch 2b is not turned on, the process proceeds to the flowchart of FIG. 15 to determine whether or not T1 has reached “0” in step SA17. The process of FIG. 15 is repeated. If T1 does not reach “0”, the process proceeds to the flowchart of FIG. 16 to determine whether or not T2 has reached “0” in step SA29, and when T2 reaches “0”. The above-described processing of FIG. 16 is repeated.

  In step SA24 of FIG. 15, when the value of KUKAN1 is larger than the value M of the last section, that is, when the lyrics of the song are finished and the accompaniment of the song including the ending part of the accompaniment is finished. , “2 (end of music)” is set in STF1 (step SA27). Then, the process proceeds to step SA5 in FIG. 13 to determine whether or not the start switch 2b is turned on. When the start switch 2b is turned on, the performance of the same finished music is started again, but when the start switch 2b is not turned on, the process proceeds to the flowchart of FIG. If STF1 is “2” instead of “1” in step SA16, or if T1 has not reached “0” in step SA17, the process proceeds to the flowchart of FIG. If STF2 is “2” instead of “1” in step SA28, or if T2 has not reached “0” in step SA29, the process proceeds to the flowchart of FIG.

  In FIG. 17, it is determined whether or not both STF1 and STF2 are “2” (step SA44). If either one is “1”, the process proceeds to the flowchart of FIG. 14 and the above-described processing is repeated. However, when both STF1 and STF2 are “2”, that is, when the music is finished. The timer interrupt 1 is prohibited (step SA45). Next, an evaluation screen is created based on the difference between the volume and pitch of the audio data stored in the RAM 13 and the volume and pitch of the model data (step SA46). The evaluation screen is displayed (step SA47).

  An example of the evaluation screen is shown on the display unit 2 in FIGS. As parameters to be evaluated, there is a shift in sound generation timing (T) in addition to a shift in pitch (P) and volume (V) stored in the RAM 13. The evaluation screen displays not only the overall evaluation but also the evaluation in each section. In addition, icons of “example” and “special training” are displayed on the evaluation screen. When the “example” icon is selected by the cursor switch 2c, as shown in FIG. 6, in order to hear and compare the model song and the song of the singer, a section comparison screen is displayed. A message prompting you to specify is displayed. As shown in FIG. 5, only the wrong section (0, 1, 2) may be displayed on the screen, or all sections (0, 1, 2,... M) are displayed as shown in FIG. It may be displayed on the screen and an NG mark may be displayed in the wrong section (0, 1, 2).

  If a message prompting the designation of a section is displayed, it is determined whether or not a section has been designated by turning on the section designation switch 2e and the numeric keypad switch 2d or the cursor switch 2c (step SA48). If the section specifying switch 2e or the like is not turned on, it is determined whether or not the return switch 2f is turned on (step SA49). If this switch is turned on, the volume of the audio data stored in the RAM 13 is determined. The pitch data is cleared (step SA50), and the process proceeds to step SA2 in FIG. 13 to display the song selection screen.

  In step SA48 of FIG. 17, when the section designation switch is turned on and a section is designated, the number of the designated section is set in the register k (step SA51), and the model data or the audio data captured from the microphone Is set to "0" (step SA52), and STF1 is set to "1" (step SA53). Further, the value of k is set in KUKAN1 (step SA54).

  Next, proceeding to the flowchart of FIG. 18, the address of the head position of KUKAN1 (k) of the accompaniment data of the song (n) is designated (step SA55). Next, the lyrics data at the designated address is read and displayed (step SA56). Next, the address is incremented, and the next data, that is, the first time data of accompaniment data is read (step SA57). Then, the read time data is stored in the register T1 (step SA58).

  Next, it is determined whether the PBF is “1 (audio reproduction)” or “0 (exemplary reproduction)” (step SA59). If PBF is “0”, STF2 is set to “1” (step SA60), and the value of k is set to KUKAN2 (step SA61). Then, the address of the start position of KUKAN2 (k) of the model data of the song (n) is designated (step SA62), and the data read from that address, that is, the first time data of the model data is stored in the register T2 ( Step SA63).

  On the other hand, if the PBF is “1” in step SA59, the flag STF3 is set to “1 (during audio playback)” (step SA64), and the value of k is set to KUKAN3 that designates the audio data section (Step SA65). Then, the address of the position corresponding to the head of KUKAN3 (k) in the audio data stored in the RAM 13 is designated (step SA66). After the first time data of the model data is stored in T2 in step SA63, or after the address of the audio data is specified in step SA66, the timer interrupt 2 is canceled (step SA67). And it transfers to the flowchart of FIG.

  Therefore, the timer interrupt 2 shown in FIG. 23 is executed every time a predetermined time elapses. That is, the time data value of T1 is decremented (step SC1), and the lyric display color changing process is performed so that the utterance timing can be recognized again (step SC2). Next, it is determined whether or not STF2 is “1” (step SC3). When STF2 is “1”, that is, when reproducing model data, the value of the time data of T2 is decremented ( Step SC4). On the other hand, when STF2 is not “1”, that is, when audio data is to be reproduced, the audio data stored at the address of RAM 13 designated at the timing of timer interrupt 1 is output to sound source unit 17 (step SC5). After outputting the audio data or after decrementing the value of T2, the process returns to the main routine.

  In the flowchart of FIG. 19, it is determined whether or not STF1 is “1” (step SA68). When STF1 is “1”, that is, when accompaniment data in the designated section k is being played. , It is determined whether or not the value of T1 has reached “0” (step SA69). When the value of T1 reaches “0”, the address is incremented and the next data is read (step SA70). At this time, it is determined whether or not the section data has ended (step SA71). If the section data has not ended, it is determined whether the read data is an event or a time (step SA72). ). If the read data is an event, it is sent to the sound source unit 17 (step SA73), and if the read data is time, it is stored in T1 (step SA74).

  After the read event data is sent to the sound source unit 17, the address is incremented, and the process proceeds to step SA70 to read the next data. On the other hand, after the read time data is stored in T1, the process proceeds to step SA68, and when STF1 is “1” and when the value of T1 reaches “0” in step SA69, The address is incremented, and the process proceeds to step SA70 to read the next data. That is, when STF1 is “1”, the event of the accompaniment data read out is sequentially sent to the sound source unit 17 as time passes unless the section data ends in step SA71.

  If the value of T1 does not reach “0” in step SA69, it is determined whether or not STF2 is “1” in the flowchart of FIG. 20 (step SA75), and STF2 is “1”. That is, when reproducing the model data of the designated section k, the screen shifts from the screen of FIG. 6 to the screen of model playback of FIG. 8, and whether or not the value of T2 has reached “0”. A determination is made (step SA76). When the value of T2 reaches “0”, the address is incremented and the next data is read (step SA77). At this time, it is determined whether or not the section data has ended (step SA78). If the section data has not ended, it is determined whether the read data is an event or a time (step SA79). ). If the read data is an event, it is sent to the sound source unit 17 (step SA80), and if the read data is time, it is stored in T1 (step SA81).

  After the read event data is sent to the sound source unit 17, the address is incremented, and the process proceeds to step SA77 to read the next data. On the other hand, after the read time data is stored in T2, the process proceeds to step SA75, and when STF2 is “1” and when the value of T2 reaches “0” in step SA76, The address is incremented, and the process proceeds to step SA77 to read the next data. That is, when STF2 is “1”, the event of the read model data is sequentially sent to the sound source unit 17 as time passes unless the section data ends in step SA78. In step SA78, when the section data is completed, STF2 is reset to “0”, and PBF is inverted from “0 (exemplary reproduction)” to “1 (audio reproduction)” (step SA82).

  If the value of T2 does not reach “0” in step SA76, the screen shifts from the screen of FIG. 6 to the audio playback screen of FIG. 7, and whether STF3 is “1” in the flowchart of FIG. (Step SA83), when STF3 is “1”, that is, when the audio data of KUKAAN3 (k), which is the designated section, is being reproduced, within the designated section of KUKAAN3 (k) It is determined whether or not the audio data has been read (step SA84). When reading of the audio data in the designated section is completed, the STF 3 is reset to “0” (step SA85), and the PBF is inverted from “1 (audio reproduction)” to “0 (exemplary reproduction)” (step SA86). ). Then, the process proceeds to the flowchart of FIG. 18 and the processes of FIGS. 18 to 21 are repeated.

  In step SA84 in FIG. 21, if the reading of the audio data is not completed, it is determined whether or not the cancel switch 2g is turned on (step SA87). If this switch is not turned on, FIG. The process proceeds to step SA68, and the processes of FIGS. 19 to 21 are repeated. On the other hand, when the stop switch 2g is turned on, the STF1, STF2, and STF3 are all reset to “0” (step SA88), and the timer interrupt 2 is prohibited (step SA89). Then, the process proceeds to step SA46 in FIG. 17 to create an evaluation screen based on the difference between the volume / pitch of the model data and the volume / pitch of the stored audio data, and prepare for the next section comparison.

  In the evaluation screen shown in FIG. 5, when the “special training” icon is selected by operating the cursor switch 2c, the screen shifts from the evaluation screen of FIG. 5 to the special training screen of FIG. A section having a timing difference larger than a predetermined value is determined as a wrong section, the section is automatically selected, and it is urged to repeatedly train the section. In this case, for example, as shown in FIG. 9, advice that matches the exemplary singing voice is displayed. Further, as in the case of the above-described listening comparison, the performance of the model data may be appropriately reproduced. As a result of repeated training, if the pitch, volume, and sounding timing shift are below a predetermined value, the screen of FIG. 10 is displayed.

As described above, according to the above embodiment, the CPU 11 converts the singer's voice signal input from the microphone according to the accompaniment of the karaoke song from analog to digital voice data, and temporarily stores it in the area of the RAM 13. The model data for the song stored in advance in the RAM 13 or the ROM 14 or the voice data temporarily stored in the RAM 13 is selectively read out and reproduced by the sound source unit 17 to compare the voice data with the model data. Then, the singing ability for the music is evaluated and output to the display unit 3.
Therefore, singers can easily improve the singing ability by easily recognizing the level of mistakes and singing the correct pitches and utterance timings, etc. it can.

In this case, the CPU 11 compares the audio data with the model data for each predetermined section of the music and outputs the evaluation result of each section to the display unit 3.
Therefore, it is possible to provide detailed guidance on accurate pitches and utterance timings.

  In the above embodiment, the invention of the karaoke apparatus, that is, the invention of the product has been described. However, a non-volatile memory such as a flash ROM is provided in the karaoke apparatus and stored in a CD-ROM or FD (flexible disk). It is also possible to install a karaoke information processing program or a karaoke information processing program downloaded from a network such as the Internet via the network interface 19 in the nonvolatile memory so that the CPU 11 executes the program. It is. In this case, the invention of the program, the invention of the recording medium, and the invention of the information processing method are realized.

That is, the invention of the program includes a first step of temporarily storing, in the predetermined storage means, the first audio signal input from the predetermined audio input means in accordance with the musical accompaniment, and the storage means or the like. A second step of selectively reading out the second audio signal for the song stored in advance in the storage means or the first audio signal temporarily stored in the storage means and causing the predetermined reproduction means to reproduce the second audio signal; A third step of comparing the first audio signal and the second audio signal to evaluate the singing ability of the first audio signal for the song and outputting the evaluation result to a computer; Let it run.
Therefore, singers can easily improve the singing ability by easily recognizing the level of mistakes in the parts where they sang the pitch or utterance timing, etc. it can.
