Description

  The present invention relates to a karaoke apparatus.

  Karaoke karaoke devices equipped with a karaoke singing scoring function are widely used in online karaoke systems. The singing of the karaoke song is performed by digitizing the singer's karaoke song and comparing it with the value of the reference data. The scoring results are displayed for each singing section during music performance using a monitor that displays lyrics and background video, or as a total score after music performance.

  For example, in Patent Document 1, pitch and volume data is extracted from a singing voice signal of a karaoke song converted into digital data, and the pitch and volume of a guide melody read in parallel with the karaoke performance music data. There has been disclosed a karaoke apparatus capable of correctly scoring and evaluating the skill of a karaoke singer by performing scoring for each section such as rust and climax compared to data and the like.

  In addition to the score evaluation, a technique for presenting evaluation comments based on comprehensive and multi-faceted evaluation is also known. For example, in Patent Document 2, various singing voices are selected by selecting and outputting an evaluation comment satisfying a condition from a large number of evaluation comments prepared in advance based on the evaluation result for each evaluation item for the singing voice. Technology that evaluates from various viewpoints and outputs information (evaluation comments) according to the evaluation results is disclosed.

  Moreover, when notifying a singer of an evaluation comment using the technique described in Patent Literature 1 or Patent Literature 2, it is not displayed on a monitor and visually informed, but prerecorded audio data or publicly known Auditory notification can also be made using a speech synthesis technique. For example, Patent Document 2 describes that the output information may be voice data that expresses the content of the evaluation comment in voice, or MIDI-format sequence data for generating sound using a sound source ( (See paragraph [0062] of the specification of Patent Document 2).

  By applying these techniques, the singer's singing voice can be evaluated for each predetermined singing section, and a message corresponding to the evaluation for each singing section can be output as a voice during performance of the music (during singing).

  In this case, as a matter of course, it is desirable to output the message by voice at a timing that does not overlap with the singing of the singer. Here, for example, Patent Document 3 discloses an invention that outputs a praise sound effect or a blame sound effect immediately after finishing the singing of the singing section based on the scoring result in each singing section (Patent Document 3). 3 specification paragraphs [0038], [0040]).

== Karaoke equipment ==
(Hardware configuration)
The karaoke apparatus 1 is an apparatus for performing karaoke performance and singing by a singer. As shown in FIG. 1, the karaoke apparatus 1 includes a karaoke main body 10, a speaker 20, a display device 30 (display unit), a microphone 40, and a remote control device 50. The karaoke apparatus 1 is communicably connected to a server (not shown) via a communication line.

  The speaker 20 is configured to emit sound based on the sound emission signal from the karaoke main body 10. The display device 30 is configured to display a video or an image on the screen based on a signal from the karaoke main body 10. The microphone 40 is configured to convert a singer's voice into an analog voice signal and input it to the karaoke main body 10. The remote control device 50 is a device for performing various operations on the karaoke main body 10. The singer can use the remote controller 50 to activate the karaoke device 1 and reserve music.

  The karaoke main body 10 performs various controls relating to karaoke singing, such as performance control of selected karaoke music, display control of lyrics and background video, and processing of audio signals input through the microphone 40. FIG. 2 is a diagram illustrating a hardware configuration example of the karaoke main body 10. The karaoke main body 10 includes a control unit 11, a communication unit 12, a storage unit 13, an acoustic processing unit 14, a display processing unit 15, and an operation unit 16. Each component is connected to the bus B via an interface (not shown).

  The control unit 11 includes a CPU 11a and a memory 11b. The CPU 11a implements various control functions by executing the operation program stored in the memory 11b. The memory 11b is a storage device that stores a program to be executed by the CPU 11a and temporarily stores various types of information when the program is executed.

  The communication unit 12 provides an interface for connecting the karaoke main unit 10 to a communication line via a router (not shown).

  The storage unit 13 is a large-capacity storage device that stores various data, and is, for example, a hard disk drive. In the present embodiment, the storage unit 13 includes a music data storage unit 13a, a message storage unit 13b, a video data storage unit 13c, and an audio data storage unit 13d.

  The music data storage unit 13a stores a plurality of music data. The music data is data for performing karaoke performance by the karaoke apparatus 1. When the karaoke apparatus 1 plays music based on music data, the singer can sing karaoke. Each song has a “singing section” that is a section in which lyrics are set for the singer to sing, and a “non-singing section (interval)” that is a section in which no lyrics are set. Exists. The non-singing section corresponds to an interval from the end of a certain singing section to the start of the next singing section.

  The music data includes MIDI data, lyrics data, reference data, and the like. MIDI data is automatic performance data (karaoke performance data) for automatically playing a sound source of an electronic musical instrument, and is composed of time-series note information. The note information is composed of various commands for controlling, for example, the timing of sound generation and mute, key pressing force, pitch, and playback pitch. The lyric data is character string data for causing the display device 30 to display the lyrics telop in the karaoke music. The lyric data is preset for each music piece. The reference data is data serving as a reference when scoring a karaoke song by a user, and is composed of time-series pitch information representing the pitch of a vocal. Reference data is set for each singing section.

  Note that the music data used in the karaoke apparatus 1 according to the present embodiment is not stored in the music data storage unit 13a but may be data obtained directly from a server (not shown).

  The message storage unit 13b stores a different message in association with each of the plurality of scoring results. FIG. 3 shows an example of table data in which a plurality of scoring results and messages are associated with each other. Note that the message of the present embodiment is a wording adapted to the image of each character so that there is no sense of incongruity even when used in a “character scoring mode” described later.

  Each message is divided into a plurality of parts. A “part” is an area in which the content of a message is divided in units of words. The message storage unit 13b stores priority information and time information in association with each part.

  The priority information is information given according to the importance of each part in one message. The message is composed of a combination of parts, but the words included in each part include words that clearly indicate the message content ("great", "do your best") to simple exclamations ("O ~", " There are a variety of things up to ah. Therefore, the importance according to the content of the phrase can be set in advance for each part. For example, the message M03 in FIG. 3 is divided into three areas “Ufu”, “Nakanaka”, and “Yaruwanee ~” as a plurality of portions. Of these, the message content that the singer wants to convey most, that is, the area of “Yaruwanee ~”, which is the part with the highest importance, is given priority information “A (the area is the part with the highest priority). “Indicates that there is)” is set. Similarly, “B (indicating that the area is the next highest priority part)” is set as the priority information for the “highly important” area which is the next most important part, “C (indicating that the area is the lowest priority part)” is set as the priority information for the “Ufu” area which is the lowest importance part. The priority information for each part may be set according to the type of word or the like each time a message is selected.

  The time information indicates an elapsed time from the start to the end of each part in one message. The message as a whole has a predetermined length (predetermined time). Each part has a certain length within a predetermined time range. For example, the message M03 in FIG. 3 has a length of 2,100 msec in the entire three areas “Unusually good”. Among these, “Ufu” is from 0 msec to 800 msec corresponding to the start of the message M03, “Nakanaka” is from 800 msec to 1,400 msec, and “Yaruwanee” is from 1,400 msec to 2,100 msec corresponding to the end of the message M03. It is set as the length. Note that the length of words (the number of words) and the length of elapsed time do not necessarily match.

  The video data storage unit 13c is an area for storing video data such as background images and characters displayed on the display device 30 during karaoke performance.

  The voice data storage unit 13d stores voice data that expresses the content of the message stored in the message storage unit 13b by voice. For example, the voice data storage unit 13d stores the message ID and the voice data of the message in association with each other (see FIG. 4). Note that the message stored in the message storage unit 13b and the voice data stored in the voice data storage unit 13d can be associated by assigning the same message ID.

  Based on the control of the control unit 11, the acoustic processing unit 14 controls performance of the karaoke music and processes an audio signal input through the microphone 40. The acoustic processing unit 14 includes, for example, a MIDI sound source, a mixer, and an amplifier (all not shown). The MIDI sound source generates a musical sound signal based on the music data. The mixer mixes the music signal and the audio signal output from the microphone 40 at an appropriate ratio and outputs the mixed signal to the amplifier. The amplifier amplifies the mixing signal from the mixer and outputs the amplified signal to the speaker 20 as a sound emission signal. Thereby, the karaoke performance sound based on the sound emission signal and the singing voice from the microphone 40 are emitted from the speaker 20. In addition, the acoustic processing unit 14 according to the present embodiment emits a predetermined message based on the control of the audio output control unit 500 (described later).

  The display processing unit 15 performs processing related to various displays on the display device 30 based on the control of the control unit 11. For example, the display processing unit 15 controls the display device 30 to display a video in which lyrics telop is superimposed on a background video during karaoke performance.

  The operation unit 16 includes a panel switch and a remote control receiving circuit, and outputs operation signals such as a reservation signal and a stop signal to the control unit 11 according to the operation of the panel switch of the karaoke device 1 or the remote control device 50 by a singer. To do. The control unit 11 detects an operation signal from the operation unit 16 and executes a corresponding process.

(Software configuration)
FIG. 5 is a diagram illustrating a software configuration example of the karaoke main body 10. The karaoke main body 10 includes a scoring unit 100, a message selection unit 200, an interval detection unit 300, a timing determination unit 400, and an audio output control unit 500.

  The scoring unit 100, the message selection unit 200, the interval detection unit 300, the timing determination unit 400, and the audio output control unit 500 are realized by the CPU 11a of the control unit 11 executing an operation program stored in the memory 11b.

  The scoring unit 100 calculates a scoring result for each singing section for music having a plurality of singing sections. A known method can be used to calculate the scoring results. For example, when the singer performs a song in a certain singing section, the scoring unit 100 acquires a singing voice signal based on the singing. And the scoring part 100 calculates the scoring result based on a pitch by reading the reference data corresponding to the said song area from the music data storage part 13a, and comparing the acquired song audio | voice signal and reference data. The scoring result is calculated as, for example, score information in the range of 0 to 100 points. Note that the scoring unit 100 may calculate not only the scoring result based on the pitch, but also a comprehensive evaluation that combines the singing volume and timing (rhythm), and the evaluation result of the singing technique, as the scoring result.

  The message selection unit 200 selects a predetermined message according to the scoring result calculated by the scoring unit 100. Specifically, the message selection unit 200 reads the message corresponding to the scoring result of the scoring unit 100 as a predetermined message with reference to the table data in the message storage unit 13b. The message is associated with priority information and time information for each part.

  The interval detection unit 300 detects the length of the interval that is the interval from the end of the singing section for calculating the scoring result to the start of the next singing section. For example, the interval detection unit 300 detects the length of the interval based on the music data stored in the music data storage unit 13a. Information regarding the length of the interval may be recorded in advance as the music data. In this case, the interval detection unit 300 detects the length of the interval by reading the information from the music data storage unit 13a.

  The timing determination unit 400 determines the timing for starting the voice output of the predetermined message based on the detected interval length and the priority information and / or time information corresponding to the selected predetermined message. Details will be described later.

  The voice output control unit 500 controls the acoustic processing unit 14 so as to output a predetermined message voice at the determined timing. Specifically, the audio output control unit 500 reads out audio data corresponding to a predetermined message from the audio data storage unit 13 d and transmits the audio data to the acoustic processing unit 14. The sound processing unit 14 emits a message corresponding to the sound data from the speaker 20 based on the control of the sound output control unit 500. That is, the “sound output control unit 500”, “sound processing unit 14”, and “speaker 20” constitute a “message output unit” that outputs a predetermined message as a sound at a determined timing. In addition, when performing voice output, it is also possible to use text data instead of using voice data recorded in advance. In this case, the voice data storage unit 13d stores the text data and the message ID in association with each other. Then, the acoustic processing unit 14 performs speech synthesis based on text data corresponding to a predetermined message, and emits a predetermined message content.

== About timing determination ==
Next, a specific example of timing determination by the timing determination unit 400 will be described with reference to FIGS. 6A to 6E. 6A to 6E are diagrams schematically showing a relationship between a song singing section and interval and a timing at which voice output of a message is started (hereinafter sometimes simply referred to as “timing”). In this example, the message is divided into three areas: a part A having the highest priority, a part B having the next highest priority, and a part C having the lowest priority. Hereinafter, the description will be given separately for the case where the length of the interval is longer than the length of the predetermined message and the case where the interval is shorter. The timing determination unit 400 compares the interval length with a predetermined message length based on the time information.

(When the interval length is shorter than the predetermined message length)
The timing determination unit 400 determines the timing so that the highest priority part in the predetermined message is output longer during the interval.

  For example, the timing determination unit 400 determines the timing so that the audio output of the portion A having the highest priority is started at the start of the interval (see FIG. 6A). By determining the timing in this way, since the message of the part A having the highest priority is emitted from the start of the interval not affected by the singing, the singer can easily grasp the important part of the message. .

  In the example of FIG. 6A, all messages corresponding to the portion A with the highest priority are emitted, but there may be a case where the length of the portion with the highest priority is longer than the length of the interval. (See FIG. 6B). Also in this case, the timing determination unit 400 determines the timing so that the audio output of the portion A having the highest priority is started at the start of the interval. By determining the timing in this manner, at least a part of the message of the part A having the highest priority can be emitted during the interval, so that the singer can easily grasp the important part of the message even a little.

  When the length of the portion A with the highest priority is shorter than the length of the interval, the timing determination unit 400 determines that the portion A with the highest priority and the portion B with the next highest priority are intervals. It is also possible to determine the timing so that audio is output during the period (see FIG. 6C). For example, the length of the detected interval is 1,000 msec, the length of the selected message is 1,400 msec, the length of the highest priority part A is 800 msec, and the next highest priority part B Assume that the length is 300 msec. In this case, the timing determination unit 400 compares the length of the interval with the length of the portion A having the highest priority, and obtains the remaining interval length of 200 msec. Then, a time point that is 100 msec earlier than the start of the interval is determined as a timing for outputting the voice of the message so that a part (200 msec) of the portion B enters the remaining interval. By determining the timing in this way, since the messages are emitted in order of priority from the highest priority portion A during the interval, it is easy for the singer to grasp the contents of the messages in order of importance of the messages. Become.

(When the interval length is longer than the predetermined message length)
In this case, the timing determination unit 400 can determine the start time of the interval as the timing (see FIG. 6D). By setting the timing in this way, all messages can be emitted during the interval. Therefore, the singer can easily grasp the contents of the entire message including the portion A having the highest priority.

  Alternatively, the timing determination unit 400 can also determine a time point delayed by a predetermined time from the start time of the interval as the timing (see FIG. 6E).

  For example, assume that the detected interval length is 1,400 msec and the selected message length is 1,200 msec. In this case, the timing determination unit 400 determines a time point that is 100 msec later than the interval start time as the timing. By setting the timing in this way, a predetermined interval (100 msec in the example of FIG. 6E) is generated between the previous singing section, the next singing section, and the message. That is, since the interval between the singing section and the sound emission period of the message is large, the message contents can be easily heard. Therefore, it becomes easier for the singer to grasp the contents of the entire message including the portion A having the highest priority. When the interval length is longer than the predetermined message length, priority information is not used for timing determination.

  Moreover, it is not restricted to the said example from a viewpoint of determining the timing that the part with the highest priority is output longer during an interval. For example, the timing determination unit 400 first compares the length of the interval with the length of the portion A with the highest priority, and determines whether the length of the interval is longer or shorter than the length of the portion A with the highest priority. .

  When the length of the interval is longer than the length of the portion A having the highest priority, the timing determination unit 400 further compares the length of the entire message with the length of the interval.

  When the length of the interval is longer than the length of the entire message, the timing determination unit 400 determines the start time of the interval as the timing (see FIG. 6D), or uses the time point delayed by a predetermined time from the start time of the interval as the timing. Determine (see FIG. 6E).

  Also, if the length of the interval is shorter than the length of the entire message, the timing determination unit 400 determines the timing so that the voice output of the portion A having the highest priority is started at the start of the interval (FIG. 6A). The timing is determined so that the part A having the highest priority and the part B having the second highest priority are output during the interval (see FIG. 6C).

  On the other hand, when the length of the interval is shorter than the length of the portion A having the highest priority, the timing is determined so that the voice output of the portion A having the highest priority is started at the start of the interval (see FIG. 6B).

== About the operation of the karaoke apparatus 1 ==
Next, a specific example of the operation of the karaoke apparatus 1 according to this embodiment will be described with reference to FIGS. FIG. 7 is a flowchart showing an operation example of the karaoke apparatus 1. FIG. 8 is a musical score showing a part of a nursery rhyme “Fujinoyama” (Lyrics: Minami Kajitani) which is the Ministry of Education's song.

  The singer selects the song “Fujinoyama” via the remote control device 50 and sings (music selection / singing, step 10).

  The scoring unit 100 is the first singing section, 87.5% of the first 8 bars of the song “Ama Omomono ni wo shi no ya mio iro sei te wo wo wo wo wo wo wo wo wo” When the singing of “Mioroshii” of the bar ends, 85 points are calculated as the scoring result of the singing section (calculation of scoring result, step 11). If scoring results are calculated for all the songs in the singing section, the voice output of the message may not start in time. Therefore, it is desirable to obtain a scoring result at the time when, for example, about 80% to 90% of the singing is completed in a certain singing section. In the present invention, “calculating a scoring result for each singing section” includes a case where a scoring result is obtained based on a part of singing in a singing section.

  The message selection unit 200 refers to the table data (see FIG. 3) stored in the message storage unit 13b, and selects the message M03 corresponding to the scoring result of 85 points (message selection, step 12).

  The interval detection unit 300 refers to the reference data of the song “Fujinoyama” selected in step 10, and after the singing of the first singing segment (“te” in the eighth measure) is completed, the next singing segment (“ The interval length of 750 msec until the start of “Kanami Sama (...)” is detected (interval detection, step 13). As shown in the score of FIG. 8, the interval of this music is 1 beat (quarter rest), and BPM is 80. Therefore, the interval is 60/80 = 0.75 sec.

  The timing determination unit 400 determines the timing for starting voice output of the message M03 based on the length of the interval detected in step 13 and the priority information and time information corresponding to the message M03 selected in step 12. (Determine timing. Step 14).

  In this example, the total length of the message M03 is 2,200 msec with respect to the detected interval length of 750 msec. Therefore, the timing determination unit 400 outputs the message M03 as an audio signal at a timing that is 1,400 msec earlier than the start of the interval so that the highest priority part “Yaruwanee ~” does not overlap with the singing voice (singing section). The timing to start.

  Based on the control of the audio output control unit 500, the acoustic processing unit 14 outputs the message M03 through the speaker 20 at the timing determined in step 14 (message sound emission; step 15).

  As described above, according to the karaoke apparatus 1 according to the present embodiment, during the non-singing section (interval) in which the singing voice is not emitted, the most important part of the message corresponding to the singing evaluation can be output as voice. it can. Therefore, the singer can easily grasp the contents of the message without being affected by the voice of his / her song.

  In addition, when a singer sings, it is also possible to utilize "character scoring mode". The character scoring mode is a mode that the karaoke apparatus 1 has. When the character scoring mode is selected, the display processing unit 15 (the control unit 11) causes the display device 30 to display the character together with the background image and the lyrics when singing, and changes the character display mode according to the progress of the music. By installing such a mode, the karaoke apparatus 1 can give a higher preference to the singer.

  In such a mode, the display processing unit 15 (the control unit 11) can also perform control to change the character display mode in accordance with the voice output timing of the message. For example, when the content of the message is “praise”, the display processing unit 15 displays an animation that makes the character happy. Further, by changing the character's facial expression according to the sound of the message, it is possible to give a visual effect as if the message is being sounded as a character's speech. In such a case, the singer can grasp the outline of the message visually.

  The above embodiment is presented as an example and does not limit the scope of the invention. The above configurations can be implemented in appropriate combination, and various omissions, replacements, and changes can be made without departing from the scope of the invention. Those embodiments and modifications thereof are included in the invention described in the claims and equivalents thereof as well as included in the scope and gist of the invention.
