Description

  The present invention comprises storage means for storing accompaniment data and lyric data of karaoke music, voice input means for inputting a singer's voice, and a control unit for controlling karaoke performance and display display of the music selected by the singer. It is related with the karaoke apparatus which determines whether the singer could sing the lyrics correctly.

  2. Description of the Related Art Karaoke devices that have been provided with a singing ability scoring function to enhance entertainment are widely used. This kind of karaoke device compares and collates the singing timing, scale, tempo, etc. of the singer's vocal data input from the microphone with the music data, and scores it, for example, on a 100-point scale. The score is configured to be displayed on the display.

  Recently, in order to further enhance entertainment and production effects, it has been proposed to combine the scoring function with other functions, or to enhance the scoring function itself.

  For example, in the following Patent Documents 1 and 2, a technique is proposed in which the singing ability is scored in the middle of the music, and the music performance is forcibly terminated when it falls below the reference score. Moreover, in patent document 2, the scoring standard of singing ability is selected at random from a pitch, a tempo, and a volume, and it becomes the structure which can vary a scoring result even if the same person sings the same music.

  Further, Patent Document 3 discloses a technique for partially or completely hiding the lyrics of a musical piece being played and determining whether or not it matches the lyrics sung by the singer.

JP-A-9-166992 JP-A-2005-195852 JP-A-10-91172

  By the way, any of the karaoke apparatuses described in Patent Documents 1 and 2 described above evaluates the skill of the singer's singing based on the scale and tempo. Therefore, people who are skilled in singing and those who know the scoring method and standards can always get high scores, while those who are not skilled always get low scores.

  On the other hand, in the conventional karaoke apparatus, a device has been devised to make it easy to sing even an unfamiliar song by displaying lyrics telop on the display and changing the display color of the lyrics in synchronization with the music performance.

  Therefore, with a conventional karaoke device, a person who is skilled in singing can get a high score even with a song that hardly knows the lyrics, but a person who is unskilled is also high in the 18th song that memorizes the lyrics. It is an unfair situation that it is difficult to get a score. In addition, although the coincidence rate is automatically determined based on the scale, tempo, etc., there are not a few cases where the evaluation result / sensation of the singer and the like is shifted and the scoring result cannot be convinced. Therefore, even when competing for scores with friends at first, the reliability of the score gradually decreases, resulting in lack of excitement.

  On the other hand, in the prior document 3, it can be said that the above-mentioned feeling of unfairness is reduced because the lyric can be accurately sung is included in the scoring standard. However, in this prior art document 3, when the song has been sung to the end, in addition to the scale, tempo, and volume, the lyric is included in the scoring standard, so the singer can determine the accuracy of the lyrics ( I can't understand how much error is reflected in the score. In addition, if only the final scoring results are displayed, there is a risk of lack of novelty and getting bored immediately.

  The present invention was made in order to solve such problems, and based on whether or not the lyrics can be accurately sung to the end, the only scoring standard improves the objectivity and reliability of the scoring results (scores), and the production effect An object of the present invention is to provide a karaoke apparatus that can be improved.

  In order to achieve the above object, the present invention provides a storage means for storing accompaniment data and lyrics data of karaoke music, a voice input means for inputting a singer's voice, and a karaoke performance and display of the music selected by the singer. A karaoke apparatus comprising a control unit for controlling display, wherein the control unit displays on a display a background video associated with accompaniment data being played and does not display a lyrics telop, and an input Means for converting the singer's voice into digital data, extracting the character data of the lyrics sung by the singer, and the character data of the extracted lyrics and the lyrics data stored in the storage means during karaoke performance And a means for determining whether the lyrics sung by the singer are matched by comparing them with a predetermined period, and if it is determined that they do not match, Characterized in that a karaoke performance ending means forcibly ends the orchestra playing.

  According to the present invention, since the only scoring criterion is whether or not the lyrics can be accurately sung to the end, even those who are not skilled at singing can aim for a high score. Moreover, since the singer and the audience can easily evaluate whether or not the lyrics can be accurately sung, the reliability of the scoring results is improved. Furthermore, if the lyrics are wrong, it can be forced to end even in the middle of the song, giving a moderate tension and enhancing entertainment.

  Thereby, the karaoke apparatus which can improve the objectivity and reliability of a scoring result (score) and can also improve a production effect can be obtained.

  Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

<Schematic configuration of karaoke equipment>
FIG. 1 is a functional block diagram showing a schematic configuration of a karaoke apparatus according to an embodiment of the present invention, and FIG. 2 is a flowchart showing processing steps. The karaoke apparatus 1 is configured as a communication karaoke system that performs karaoke performance by reproducing music data distributed from a host computer (not shown) via a communication network, and serves as an input device connected to the karaoke apparatus body 2. A microphone (voice input means) 3, left and right channel speakers 4 (only one is shown) as an output device, and a display device 5 are configured. These input / output devices are connected to a video interface circuit, a mixing amplifier 23, and the like via output terminals (not shown). Note that an operation panel and a remote control for the singer to input or cancel a music request and change various settings such as tempo and key are not shown.

  The karaoke apparatus main body 2 includes a CPU 11 that controls the entire apparatus such as karaoke performance and display display of music selected by the singer and communication control with a host computer, and data related to music (MIDI standard data, lyrics data, background video). Data storage area 12a for storing data etc., and a program storage for storing a system program (karaoke program) for performing karaoke performance and a program (lyric scoring program) for realizing the lyrics scoring function that is a feature of the present invention An HDD (storage means) 12 having an area 12b and a work RAM 13 are provided. The HDD (storage means) 12 is connected to the CPU 11 via the HDD controller 14 and the system bus 15. The karaoke program and the lyrics scoring program read from the HDD 12 in the HDD controller 14 are stored in the work RAM 13 by the CPU 11, and the CPU 11 performs various controls of the karaoke apparatus 1 according to these programs.

  The CPU 11 also has a VDP (Video Display Processor) 17 and a video RAM 18 for displaying image image data such as CG images and various standard messages on the display device 5 via the system bus 15. , A DSP (Digital Signal Processor) 19 and voice RAM 20 for performing music reproduction and voice recognition of a singer input from the microphone 3, and a D / A converter 21 and A for mutually converting digital data and analog data The / D converter 22 is connected to a mixing amplifier 23 that mixes the music data and the voice of the singer and outputs them to the speaker 4. Here, since the gist of the present invention is to determine whether the singer can accurately sing the lyrics, the VDP 17 displays only the image data on the display device 5 in the lyrics scoring mode in which the lyrics are sung accurately. The lyrics telop is not displayed as in the conventional karaoke apparatus. The VDP 17, DSP 19 and CPU 11, and a karaoke program stored in the HDD 12 constitute a control unit. In such a basic configuration, when the song code of the requested song is input via the operation panel (remote control) and the order of the song arrives, the CPU 11 determines the karaoke performance (accompaniment) data to the DSP 19 and the lyric data to match the lyrics. The background video data is output to the unit 28 in synchronization with the VDP 17. Note that the lyrics scoring mode and the normal mode can be switched with a remote controller or the like.

  In the data storage area 12a of the HDD 12, for each piece of music, the sound source data of the music to which an address value corresponding to the time during the music is added, the image image (background video) data that matches the image of the music, the attributes of the music (performance) Code for identifying the person, famousness, genre, etc.) and lyrics data. In the sound source data of music, a plurality of flags for identifying the beginning and end of a cycle for determining lyrics (such as one measure) are arranged at predetermined intervals on a time axis indicating performance timing. That is, in MIDI data in which accompaniment sounds are described along a performance time series, address values at the start and end of scoring units such as the start and end of a scoring section are described in specific accompaniment sounds. Then, whenever the VDP 17 detects a start flag from the music data during the performance of the music, the lyrics phrase associated with the VDP 17 is read from the HDD 12 and transferred to the lyrics match determination unit 28 described later, and the end flag is set. The song data is transferred to the character conversion unit 27 every time it is detected.

  In the present embodiment, in the data storage area 12a, at least any one of background video to be displayed on the display device 5, sound effect / accompaniment sound to be output from the speaker 4, or singer's voice according to the number of errors in the lyrics of the singer. A plurality of effect patterns for changing the above are stored.

  For example, when the allowable error count of lyrics, which will be described in detail later, is set to a value of 2 or more, every time a mismatch of lyrics is detected (every allowable count is subtracted), the background video is gradually darkened. It is replaced with another video, the display area displayed on the display device 5 is gradually reduced, or the volume of accompaniment data is gradually reduced. Thereby, a pressure can be given to a singer in a form that the audience can clearly see, and entertainment can be improved. Such production patterns include background video type codes (bright / fun image to medium / dark / lonely / sad image with multiple levels, brightness / saturation with multiple levels, etc.), accompaniment data with multiple levels of volume level codes, etc. Are recorded in association with the allowable number of errors (or the number of errors, accuracy, deduction points, etc.).

  Here, “Lyrics error count” means the number of characters that are mistaken or missed (forgetting to sing), and “Error tolerance count” is the upper limit of how many mistakes (how many characters) are allowed. means.

  The data storage area 12a also includes a phoneme / lexical database and a telop timing table that are used to determine whether the lyrics match. In the phoneme / lexical database, phoneme / lexical data converted from the singer's singing data by a character conversion unit 27 described later is recorded. This phoneme / lexical data is recorded at any time during the performance of the music and cleared when the next music performance is started. The telop timing table is generated according to the MIDI sequencer included in the music data described above, and describes the timing at which each character of the lyrics should be sung as shown in FIG.

  On the other hand, the computer program stored in the program storage area 12b of the HDD 12, except for the conventionally known program for reproducing karaoke data, and the like, only the functions related to the present invention are listed. A unit 26, a character conversion unit 27, a lyrics match determination unit 28, a karaoke performance end unit 29, and an effect processing execution unit 30. Each of these functional units 25 to 31 implements each function described below by being called and executed by the CPU 11, VDP 17, and DSP 19 by the work RAM 13 or the like.

  The allowable error count setting unit 25 sets the allowable error count on a predetermined basis for each predetermined time or predetermined phrase of the music, and stores it in the HDD 12 in association with this time or phrase time address value in the music data. It is. Specific criteria for setting the allowable error count will be described in detail later.

  The voice input receiving unit 26 receives voice data of a singer input from the microphone 3 and converted into digital data by the A / D converter 22, and transfers it to the character conversion unit 27.

  The character conversion unit 27 first converts the singer's voice data transferred from the voice input reception unit 26 into phonemes, converts the phonemes into characters, and describes them in the phoneme / lexical database. For this character conversion, general-purpose speech recognition technology (dictation) can be used. For example, a phoneme string is calculated by fitting the singer's input speech to an acoustic model and replaced with kana phonetic symbols (a, ka, sa, ta, na...) An acoustic analysis such as analysis is performed to convert the data into feature data, and the recognition decoder applies the feature data to the acoustic model and outputs it in the form of text data. In addition, in order to improve the accuracy of voice recognition, it is necessary to adjust the sound level of the microphone before singing or to enroll (analyze and register the tendency of the voice characteristics of the singer) as necessary. preferable.

  The lyric coincidence determination unit 28 determines the character of the converted lyric and the character of the lyric data stored in the HDD 12 (telop timing table) for a predetermined period (scoring period of 10 seconds, one measure, etc.) during karaoke performance. In this case, it is determined whether or not the lyrics sung by the singer matches the lyrics in the cycle. When it is determined that the lyrics do not match, the determination result is transferred to the karaoke performance end unit 29.

  Here, the accuracy of lyric determination is also affected by the accuracy of speech recognition, microphone input volume, ambient noise, and so on. On the other hand, there is a risk of lack of reliability and killing interest. Therefore, for example, it is preferable to set an allowable error such as “determined that the vowels and the number of phonemes are the same”.

  The karaoke performance ending unit 29 acquires the number of times (number of errors) that the lyrics match determination unit 28 has determined that “the lyrics do not match”, counts the number of determinations and the total from the beginning of the singing, and performs the number of times In addition to transferring to the execution unit 30, it is determined whether or not the total number of errors exceeds the allowable number of errors, and if it exceeds, the karaoke performance is forcibly terminated.

  Here, the timing to forcibly end may be the time when it is determined that the allowable number of errors has been exceeded. However, as in the present embodiment, when one measure or the like is used as a scoring period, It is during the performance of the next measure that it can be determined that “the number of times allowed has been exceeded”. In this case, the singer will be forcibly terminated even if the phrase being sung is accurately sung, and the situation may not be understood. Therefore, in this embodiment, the karaoke performance is forcibly terminated not after the allowable number of times has been exceeded, but after the scoring period (measures, etc.) to which that time belongs. Thus, after the forced termination is determined, the singer's score, the number of errors, etc. can be displayed on the display device 5, the time for performing accompaniment processing such as fade-out of accompaniment, replacement of image images, message display, etc. can be secured. Can understand the situation.

  The effect processing execution unit 30 reads an effect pattern corresponding to the total number of errors of the singer received from the karaoke performance end unit 29 from the HDD 12 during the karaoke performance, and executes the effect process according to the pattern. . For example, the display device 5 displays a score or a fixed message associated with the score on the VDP 17, and instructs the DSP 19 to perform an effect process such as decreasing the volume level of karaoke performance or increasing the tempo. In this embodiment, in this embodiment, four stages A to D (rank D is forcibly terminated) are set according to the number of errors.

  For example, when the allowable error count is set to 10, the rank A is in the range of 0 to 3 and the rank B is in the range of 4 to 7, the rank B is in the range of 8 to 10, the rank D is in the range of 11 to 10. If the rank is D, the karaoke performance is forcibly terminated. In this embodiment, the accuracy of the lyrics is determined in units of characters or words. However, when a mistake in the lyrics occurs in a plurality of characters or words such as the first and second lyrics being mixed. It is thought that there are not many. Therefore, if the production process is switched once every time (one character, etc.) is mistaken, the production process is frequently switched and the process becomes complicated, and there is a possibility that the singer and the audience cannot recognize the production effect because the process is switched too early. is there. Therefore, it is effective to provide a range for the number of mistakes and to switch the production effect to the extent that a singer or the like can recognize it. A table for such ranking is stored in the HDD 12.

<Automatic error tolerance setting process>
Next, the automatic setting process of the allowable error number of lyrics based on the attribute of the music, which is executed by the allowable error number setting unit 25 will be described in detail. The following example can be considered as the relationship between the music attributes and the setting criteria for the allowable number of errors.

  When the tempo (attribute) of the music is high tempo, it is difficult to sing the lyrics accurately, so the allowable number of times (Nh) is set to a relatively large value, and when the tempo is slow tempo, the number of times (Ns) is set small. (Nh> Ns). A table in which the number of times is set according to an algorithm using a numerical value of tempo (quarter note = 60, etc.) or the number of times is preset in multiple stages according to the value of the tempo is prepared, and the number of times is extracted from this table. Also good.

  If the song's lyrics / composition or performance artist (attribute) is prominent, it is presumed that there are many people who remember the lyrics, so the allowable number of times (Nf) is set to a relatively small value and it is not prominent Sets a large number of times (Nu) (Nu> Nf). Since the determination of celebrity includes a subjective element, it is preferable to limit the number of prominent artists and the like, and to ensure objectivity by assuming that it is not prominent. The prominence may be set in a plurality of stages, and the allowable number may be set according to this.

  If the genre (attribute) of the song is Kayokyoku, Enka, J-pop, or a nursery rhyme, it is estimated that there are many people who remember the lyrics, so the allowable number of times (Nj) is set to a relatively small value. In the case of a word song or the like, the number of times (Nf) is set large (Nf> Nj). Information such as the gender, age, and preference of the singer may be input in advance, and the genre may be switched in relation to the information.

  If the release date (attribute) of the song is old, it is estimated that there are many people who remember the lyrics. Therefore, the allowable number of times (No) is set to a relatively large value, and the number of times (Nn) for the latest song. ) Is set small (No> Nn). Also in this case, it is preferable to determine the new and old reference times in relation to personal information such as the singer's age. For example, if the singer is 25 years old, a song released before 19 years before the age of entering elementary school (6 years old) is judged as an “old song”.

  When the degree of prominence (attribute) of the song is prominent, it is presumed that there are many people who remember the lyrics. Therefore, the allowable number of times (Nf) is set to a relatively small value. Is set large (Nf> Nn). As the degree of prominence of a song also includes subjective judgment as described above, for example, a song that sold more than 500,000 records and CDs, a song that was used in a movie with a certain amount of box office revenue and audience mobilization, and viewing Music used in TV dramas and animations with a certain rate or more, music used in TV CM for a certain period of time, music ranked more than once in a weekly sales or wired request ranking (1 week), etc. Regarded as “famous music”, other music is judged as non-famous music. Also in this case, the degree of prominence may be determined in relation to personal information such as the gender, age, address, and birthplace of the singer.

  The above-mentioned song attributes and the number of error tolerances can be set by combining multiple items such as old songs by famous artists, foreign language songs used in famous foreign movies, and high rankings in request rankings. May be. In addition, in the case of a general karaoke box or the like, a singer or the like inputs in advance to acquire the above-mentioned “personal information”, but if it is a communication karaoke system using a mobile phone or cable TV, it is registered in advance. Personal information can be used.

  In addition, the error tolerance number automatically set when the request for the music is received is displayed on the display, and the singer can input the increase / decrease in the number before or during the singing, or after the lyric scoring starts. The allowable number of errors may be changed dynamically.

  For example, at the time of request reception, the allowable number of times is set to 10 because it is an old song that is not famous, but if the number of errors is 0 at the end of singing No. 1, it is a song that this singer knows well It is judged that there is, and the allowable number of times is reduced (for example, three times). Also, if the composition of the music is No. 1, No. 2 and repeat, even if the allowable number of errors is initially set to 10 times, it is reset to 5 times at the end of No. 1 and further once at the end of No. 2 You may make it reset. In this case, the total number of allowable errors of No. 1 and No. 2 is not 10, but No. 1 is allowed 5 times, No. 2 is 4 times, and the repeat part is allowed up to once. On the contrary, in general, it is more likely that No. 2 will not remember the lyrics than No. 1, so change 10 times to 8 times at the end of No. 1 (allowed up to 2 times) and 1 at the end of No. 2 You may make it change again to once (allowed up to seven times). This makes it possible to automatically set a handicap or determine lyrics according to the singer's singing level or preference. Such a change in the allowable number of times in the music may be arbitrarily operated by a singer or the like.

<Lyric scoring process>
Finally, with reference to the flowchart of FIG. 2, the lyrics scoring process according to this embodiment will be described in detail. This lyrics scoring function is executed in addition to a normal karaoke performance by a control unit such as the CPU 11 when a request for lyric scoring is received from a singer or the like through an operation panel or the like. In the following description, the CPU 11, the VDP 17, and the DSP 19 will be collectively referred to as a control unit. Note that description of processing common to normal karaoke performance is omitted or simplified.

  First, when a karaoke song selection and lyrics scoring request is received from a singer or the like, the previous allowable number of times set in the internal memory or the like of the control unit is cleared, and the error allowable number setting unit 25 The attribute of the music is read from the HDD 12, the allowable number of times is set according to the attribute, and stored in the internal memory in association with the music code (S1). In the present embodiment, the allowable error count is set to 10 (10 characters) (n: 10).

  When karaoke performance of the requested music starts, the voice input reception unit 26 acquires digital singing voice data input from the microphone 3 and sampled and converted by the A / D converter 22, and converts the singing voice data into lyrics characters. (S2, S3). Then, the converted character is transferred to the lyrics match determination unit 28 in the form of a character code (S4). These processes are executed in synchronization with the lyrics determination cycle, and character conversion / transfer is also performed for each measure in accordance with the determination cycle.

  When the control unit detects a flag set at the starting point of each measure of the musical piece being played, the lyrics data of the measure is extracted from the HDD 12 and transferred to the lyrics match determination unit 28 in the form of a character code (S5). ).

  The lyric coincidence determination unit 28 collates the character codes of the transferred lyric data and singing voice data character by character to determine whether they match (S6). When an error in the lyrics is detected (No in S6), the number of times is transferred to the karaoke performance end unit 29. The karaoke performance ending unit 29 substitutes n + 1 for the number of errors n, calculates the accumulated value and stores it in the memory (S7), and the accumulated value exceeds the allowable error number (10 times) set in S1. It is determined whether it is not (S8).

  When the number of errors exceeds the allowable number (n ≧ 11), the karaoke performance end unit 29 forcibly ends the music being played (S9). Specifically, the control unit stops the processing such as reading and outputting the music data being played and outputting the background image in synchronization with the end of the measure to which the determination time belongs. At this time, the effect processing execution unit 30 displays a fixed message for a predetermined period of time, such as a numerical value of the correct answer rate (match rate), and a standard message associated with the correct answer rate, such as “There is not enough practice yet” or “It was a little more”. The lyric scoring process is terminated by displaying on the device 5 (S10).

  On the other hand, when the number of errors is less than the allowable number (n <10), the karaoke performance end unit 29 transfers the number of times to the effect processing execution unit 30 (S11). The effect processing execution unit 30 reads an effect pattern based on the acquired number of errors (cumulative value) from the HDD 12 (S12-1 to S12-3), and executes the effect process along the pattern (S13). Specifically, the VDP 17 and DSP 19 are instructed to change the display size of the background image, the output level (volume) of the accompaniment data, the replacement of the background image, and the like.

  The above processing is continuously executed until the number of errors reaches an allowable number or until the karaoke performance of the music is finished (S14). The same applies when it is determined that the lyrics match (Yes in S6). Finally, the production processing execution unit 30 gives a standard message and a score (such as the number of errors) such as “Congratulations on Perfect”! The lyric scoring process is terminated by displaying on the display device 5 for a predetermined time (S10).

  In addition, this invention is not limited to said embodiment, A various change is possible.

  For example, in the above embodiment, the number of errors and the correct answer rate are displayed on the display device 5, but the score obtained by adding or subtracting the number of errors from the initial score or by converting the count number by a predetermined conversion rate is used. May be displayed. Also, the score conversion standard may be the whole music piece, or the number of matched characters (or the number of unmatched characters) per predetermined time such as one measure or 10 seconds. For example, if one bar contains the 13-letter words “Harusame will fall in the heart,” 13/13 = 100 points if you can sing all 13 characters correctly. When characters are mistaken or missing, 12/13 ≒ 93 points, when 2 characters are used, 11/13 ≒ 85 points, etc. Every time one character is missed or missed, 100 points will be deducted one by one.
