You may make it input / output. In such a case, the audio processing unit 16 does not need to perform A / D conversion or D / A conversion.
The storage unit 12 has a music data storage area 121 and a correspondence relation storage area 122 as shown in the figure. The music data storage area 121 stores a large number of music data representing music played back during karaoke performance. The music data includes accompaniment data constituting accompaniment sounds of each music in a data format such as MIDI (Musical Instruments Digital Interface) format, lyrics data representing lyrics of music displayed as lyrics telop at the time of karaoke accompaniment, It includes guide melody data representing a guide melody of music in a data format such as MIDI format. In this embodiment, the guide melody data is used as reference data that is referred to when scoring the singer's voice.
The correspondence relationship storage area 122 stores a table indicating the correspondence relationship between the viewer's behavior and the correction mode data indicating the correction mode of the scoring. FIG. 2 is a diagram illustrating an example of the contents of the table stored in the correspondence storage area 122. As shown in the figure, each item of “viewer behavior” and “modification mode” is stored in association with each other in this table. Among these items, the “viewer behavior” item includes a behavior type indicating the type of viewer behavior, such as “applause”, “shoulder”, “smile”, “depressed”, etc. Information is stored. In the item “correction mode”, correction mode data indicating a correction mode of scoring such as “+15”, “+20”, “−10”, and the like is stored. The control part 11 of the karaoke apparatus 10 corrects the scoring result of a song with reference to this table.
Next, the functional configuration of the karaoke apparatus 10 will be described with reference to FIG. FIG. 3 is a block diagram showing a functional configuration of the karaoke apparatus 10. In the figure, the scoring unit 111 and the behavior detecting unit 112 are realized by the control unit 11 of the karaoke apparatus 10 executing a computer program stored in the ROM or the storage unit 12. The arrows in the figure schematically show the flow of data. Note that the scoring unit 111, the behavior detection unit 112, and the like may be realized by hardware such as a DSP (Digital Signal Processor) dedicated to audio processing.
In FIG. 3, the scoring unit 111 compares the singer voice data supplied via the voice processing unit 16 with the guide melody data stored in the music data storage area 121, and based on the comparison result, the singer's voice data. It has a function of scoring voice (hereinafter referred to as “singer voice”). For this scoring, for example, the voice characteristics such as the pitch and power of the singer voice data and the guide melody data may be compared, and the scoring may be performed such that the scoring result is better as the difference is smaller. Note that the content of the scoring process performed by the scoring unit 111 is the same as the scoring process performed in the conventional apparatus, and the detailed description thereof is omitted here.
In this embodiment, the guide melody data is used as reference data to be referred to when scoring the voice. However, the reference data is not limited to the guide melody data, and data that can be scored using the data. Anything may be used.
Next, the behavior detection unit 112 illustrated in FIG. 3 has a function of analyzing the video signal output from the photographing unit 18 and detecting the viewer's behavior. Here, an example of viewer behavior detection processing performed by the behavior detection unit 112 will be described below. In this embodiment, the behavior detection unit 112 analyzes the video signal output from the imaging unit 18, performs a person (individual) detection process, performs a face detection process, and determines the viewer's behavior based on the detection result. To detect.
The behavior detection unit 112 distinguishes between an individual object and a moving object from a stream video for a predetermined time, and performs person detection. The behavior detection unit 112 detects the behavior of the viewer by comparing the detected motion pattern of the person with a predetermined pattern. Specifically, for example, data indicating an applause motion pattern is stored in the storage unit 12 in advance, and this data is compared with the detected motion pattern of the person, and the degree of coincidence is a predetermined amount or more. In some cases, it is determined that the viewer (person) is applauding. Similarly, the behavior detection unit 112 also determines whether or not the viewer has a shoulder, whether or not a wave is being performed, and whether or not a scrum is being formed. The behavior detection unit 112 outputs a parameter indicating the determination result to the scoring unit 111. In the case where there are a plurality of viewers, data indicating the ratio of viewers performing the operation (applause, shoulder crossing, etc.) with respect to the total number of viewers may be used as a parameter. Note that the method for detecting the viewer's behavior is not limited to this, and any method may be used as long as the viewer's behavior is suitably detected.
In addition, the behavior detection unit 112 performs skin color detection, collates the captured video with an image of a predetermined pattern, and detects a face portion from the video based on the degree of coincidence. The behavior detection unit 112 determines the orientation of the viewer's face based on the detected face part image, and outputs a parameter indicating the determination result (facing downward, etc.) to the scoring unit 111.
In addition, the behavior detection unit 112 compares the detected face image with a predetermined pattern to detect a facial expression. Specifically, for example, when data indicating a smiling face is stored in the storage unit 12 in advance, the data is compared with the detected face portion data, and the degree of coincidence is a predetermined amount or more. , Determine that the viewer is laughing. The behavior detection unit 112 outputs a parameter indicating the face determination result to the scoring unit 111. When there are a plurality of viewers, data indicating the ratio of viewers of the facial expression (smiles, etc.) to the total number of people may be used as a parameter. Note that the method for detecting the orientation and expression of the viewer's face is not limited to this, and any method may be used as long as it suitably detects the orientation and expression of the viewer's face. .
In this embodiment, the behavior detection unit 112 periodically outputs a parameter indicating the detection result to the scoring unit 111 (for example, every 10 seconds).
The scoring unit 111 analyzes the detected behavior based on the parameters supplied from the behavior detection unit 112, and corrects the scoring result based on the analysis result. Specifically, the scoring unit 111 specifies a correction mode corresponding to the supplied parameter with reference to a table stored in the correspondence storage area 122, and corrects the scoring result in the specified correction mode. . Specifically, in the example illustrated in FIG. 2, when the parameter indicating that the viewer is “smile” is received, the scoring unit 111 adds “20” to the scoring result.
In this way, the scoring unit 111 corrects the scoring result according to the behavior of the viewer, so that, for example, when there are many people who are depressed during singing, it is determined that the viewer feels “boring”. The On the other hand, if there are many people with a smiley expression while singing, it is determined that “the place has a pleasant atmosphere”. If the facial expression is recognized as “laughing”, it is determined that the place is exciting and points are added.
Next, the operation of this embodiment will be described. First, a singer operates the operation part 14 of the karaoke apparatus 10, and performs operation which selects the music to sing. The operation unit 14 outputs an operation signal corresponding to the operated content to the control unit 11. The control unit 11 selects music according to the operation signal output from the operation unit 14. The control part 11 starts the karaoke accompaniment of the selected music. That is, the audio processing unit 16 reads accompaniment data from the music data storage area 121 under the control of the control unit 11, converts it into an analog signal, and supplies the analog signal to the speaker 17. The speaker 17 emits an accompaniment sound according to the supplied analog signal. The singer sings along with the accompaniment sound emitted from the speaker 17. At this time, the voice of the singer is picked up by the microphone 15, converted into a voice signal, and output to the voice processing unit 16. The audio processing unit 16 converts the audio signal output from the microphone 15 into digital data (hereinafter referred to as “singer audio data”).
The control unit 11 performs the processing of the scoring unit 111 described above. That is, the control unit 11 compares the singer voice data with the guide melody data, and scores the singer's voice (hereinafter referred to as “singer voice”) based on the comparison result. Moreover, the control part 11 performs the process of the behavior detection part 112 mentioned above. That is, the control unit 11 detects the viewer's behavior based on the video signal from the photographing unit 18, and corrects the scoring result in a correction manner corresponding to the detected behavior.
Next, the control unit 11 outputs data indicating the corrected scoring result to the display unit 13. The display unit 13 displays the scoring result based on the data supplied from the control unit 11. The singer can grasp the scoring result for his / her song by checking the screen displayed on the display unit 13.
Thus, in this embodiment, since the control part 11 detects a viewer's behavior and performs scoring which considered the detection result, a viewer's behavior can be reflected in scoring. In this way, by incorporating the viewer's reaction into the evaluation criteria, more human evaluation points can be taken into account. The viewer's behavior often expresses the viewer's feelings during viewing, thereby making it possible to score more artificially as compared with a conventional device. Specifically, for example, when the viewer is applauding, the place is often exciting, and in this case, the scoring result is high. On the other hand, when there are many viewers who are depressed, the place is often raised, and in such a case, the scoring result becomes worse.
As described above, in this embodiment, it is possible to analyze the enjoyment on the spot using gestures and sounds that the viewer reacts in a human manner, and incorporate it into the scoring results. This makes it possible to reflect elements (human reactions) that could not be caught by the conventional parameter-based evaluation algorithm, and to add realism to scoring.
As mentioned above, although embodiment of this invention was described, this invention is not limited to embodiment mentioned above, It can implement with another various form. An example is shown below. In addition, you may combine each following aspect suitably.
(1) In the above-described embodiment, the singer's voice picked up by the microphone 15 is scored. However, the input voice may be a voice picked up by the microphone 15 or stored in the storage unit 12 in advance. Audio data may be used. Moreover, it is set as the structure which provides a communication part in the karaoke apparatus 10, and audio | voice data received via this communication part may be scored. In short, any audio data input to the control unit 11 may be used.
(2) In the above-described embodiment, the karaoke apparatus is applied as the voice evaluation apparatus according to the present invention. However, the apparatus applied as the voice evaluation apparatus is not limited to the karaoke apparatus, for example, a personal computer, a mobile communication terminal, or a portable type. Various devices such as a game machine and a portable music player are applicable as the voice evaluation device according to the present invention.
(3) In the embodiment described above, the viewer's behavior detection and voice scoring are performed in real time. However, the present invention is not limited to this, and scoring may be performed when the singing is finished. Is optional.
(4) In the above-described embodiment, the scoring result is notified to the singer by displaying it on the display unit 13, but the notification mode is not limited to this, and for example, it may be notified by outputting a voice message. Alternatively, a voice message indicating the scoring result may be output. Moreover, the form which transmits the information which shows a scoring result to a singer's mail terminal in an email format may be sufficient. In addition, information indicating the scoring result may be output to the storage terminal and stored. In this case, the singer can refer to the information by reading the information from the storage medium using a computer. it can. The scoring result may be printed out on a predetermined sheet. In short, what is necessary is just to output the information which shows a scoring result so that a message thru | or information can be conveyed to a singer by some means.
Further, the scoring result may be notified in real time during the singing, or the scoring result may be notified after the singing is finished, and the timing of notifying the scoring result is arbitrary.
(5) In the above-described embodiment, a surveillance camera installed in a karaoke box is used as a photographing unit for photographing a viewer. The imaging unit is not limited to this. For example, a video from a dedicated camera may be used, or a video from a camera provided in a mobile communication terminal or the like may be used.
In the above-described embodiment, the photographing unit has photographed a moving image. However, the present invention is not limited to this, and a still image may be photographed and a viewer's behavior may be detected based on the photographed still image. In this case, for example, the viewer is photographed every predetermined unit time (for example, 1 minute), the viewer's face is recognized from the photographed image, and it is determined whether or not the viewer is laughing. . Note that facial expression recognition other than laughter may be performed.
In short, the photographing unit may be anything as long as it captures the viewer.
In addition, the method for detecting the viewer's behavior is not limited to the method described in the above-described embodiment. For example, the viewer's voice is collected and the collected voice is analyzed to detect the viewer's behavior. May be. In this case, a sound collecting means (such as a microphone) that outputs a sound signal representing the sound collected by collecting the sound of the viewer is provided, and the sound signal output by the sound collecting means is analyzed for viewing. The behavior of a person is detected. Specifically, for example, when a sound signal output from the sound collecting means is compared with a predetermined sound pattern and the degree of coincidence is within a predetermined range, the behavior corresponding to the sound pattern May be specified as viewer behavior.
In this case, as the sound collecting means, a microphone installed in the karaoke box may be used, or a dedicated microphone for collecting the voice of the viewer may be provided.
In this case, specifically, as the voice pattern, for example, voice characteristics (pitch, spectrum, etc.) emitted in various behaviors such as voice representing boos, voice representing yaji, voice representing applause, etc. What is necessary is just to memorize | store beforehand as a pattern and collate this memorize | stored audio | voice pattern and the pattern of the collected audio | voice.
For example, when booing or gouge is detected as the viewer's behavior, the control unit 11 adds a minus point, and when applause is detected as the viewer's behavior, the control unit 11 performs point addition processing. May be.
In this case, for example, if the environmental sound recorded through the microphone is quiet, it is judged that the song is “listening to the song” and the score is increased. If there is a big applause sound in the interlude, it is judged that it is “good”. The atmosphere of the place that appears in the viewer's behavior can be added to the scoring, such as increasing the score.
Note that the viewer's behavior may be detected by performing both the analysis of the viewer's voice and the analysis of the viewer's video.
Further, as another configuration for detecting the listener's behavior, for example, an operation means operated by the viewer may be provided, and the viewer's behavior may be detected according to the operation content of the operation means. In this case, specifically, for example, an operation unit provided with various buttons for evaluating the skill of the singer's singing is provided, and when operated by the viewer, the operation unit is set according to the operated content. The operation signal is output to the control unit 11. The control unit 11 detects the viewer's behavior according to the operation signal supplied from the operation means.
As described above, the method for detecting the behavior of the viewer may detect the behavior of the viewer by analyzing the captured image of the viewer, and collects the voice of the viewer. The viewer's behavior may be detected by analyzing the collected sound, or the viewer's behavior may be detected according to the operated content. In addition, for example, a sensor or the like that detects vibration may be attached to the viewer, and the viewer's behavior may be detected according to an output signal from the sensor. In this case, for example, the greater the number of vibrations, the greater the field may be determined.
In short, any device that can detect the behavior of the viewer may be used.
(6) In the above-described embodiment, the scoring result is modified according to the viewer's behavior (reaction). However, the present invention is not limited to this, and scoring may be performed only from the viewer's behavior. Even in this case, the degree of excitement of the field can be determined by detecting the behavior of the viewer. Specifically, for example, not only in singing but also in the case of rakugo, comics, etc., by detecting the behavior of viewers and scoring, when there are multiple people who are particularly evaluated, relative Scoring is possible.
(7) In the above-described embodiment, the singer voice data and the guide melody data are compared, and the singer voice is scored based on the comparison result. However, the scoring method is not limited to this. Anything may be used as long as the person's voice is scored. Specifically, for example, the model voice data representing the model singing voice may be compared with the singer voice data, and the singer voice may be scored based on the comparison result. In this case, specifically, for example, the pitch, power, spectrum, and the like of the model voice data and the singer voice data may be compared, and the score may be scored such that the score is higher as the degree of coincidence is higher. Further, for example, the singer voices and the model voice data may be compared with singing techniques (vibrato, fist, etc.), and the singer voices may be scored based on the degree of coincidence. In short, as long as the singer's voice is scored, any scoring method may be used.
(8) In the embodiment described above, the behavior detection unit 112 is configured to periodically output a parameter indicating the detection result to the scoring unit 111, but the configuration in which the scoring unit 111 acquires the parameter is limited to this. It is not something. Specifically, for example, the behavior detection unit 112 regularly stores data indicating the detection result in a predetermined storage area of the storage unit 12, and the scoring unit 111 stores the predetermined storage. It is good also as a structure which acquires data regularly from an area | region. Further, for example, the behavior detection unit 112 is configured to store data with a time stamp in a predetermined storage area of the storage unit 12, and the scoring unit 111 refers to the time stamp of the stored data, and arbitrarily It is good also as a structure which can acquire the parameter of time (for example, 10 minutes before). In short, as long as the scoring unit 111 can acquire parameters, any acquisition method may be used.
(9) In the above-described embodiment, the control unit includes a correspondence storage unit that stores the correspondence between the combination of the type of music and the behavior of the viewer and the correction mode data indicating the correction mode of the scoring. 11 determines the type of music, specifies the correction of scoring corresponding to the combination of the determined music type and the detected behavior of the viewer with reference to the correspondence storage means, and specifies the specified scoring It is good also as a structure which corrects a scoring result by the aspect of correction of these.
FIG. 4 is a diagram showing an example of the contents of the table used in this case. As shown in the figure, this table stores items of “music type”, “viewer behavior”, and “modification mode” in association with each other. Among these items, the “music type” item stores music type information representing the type of music such as “ballad”, “rap”, “arbitrary”, and the like. Note that an item whose “music type” is “arbitrary” is an item referred to in all music types. In the item “viewer behavior”, behavior type information indicating the type of viewer behavior such as “smile” and “applause” is stored. The item of “modification mode” stores correction mode data indicating the mode of scoring correction, such as “−10”, “+20”, “+15”, and the like.
In this aspect, the control unit 11 of the karaoke apparatus 10 first determines the type of music. This determination may be made, for example, from a song code included in the song data, or the genre data indicating the genre is included in the song data, and the control unit 11 determines the type by referring to this genre data. May be. Moreover, the control part 11 may analyze the rhythm, tempo, melody, etc. of a music, and may determine the kind of music based on the analysis result. When determining the type of music, the control unit 11 searches this table using a combination of the determined type of music and the detected viewer's behavior as a key, and corrects the scoring result in the searched correction mode.
According to this aspect, even if the behavior of the viewer is the same, different scoring corrections can be performed according to the type of music (for example, ballad, rap, etc.).
(10) In the above-described embodiment, the unique scoring is performed for one piece of music, but instead of this, the scoring method may be changed according to the portion of the music. For example, the scoring process and the scoring correction process may be performed only on the rust portion of the music. Also, for example, referring to the table shown in FIG. 4 described above, the first half of the music is corrected in the correction mode corresponding to “ballad”, while the second half of the music is changed to “rap”. You may make it correct scoring by the aspect of corresponding correction.
Further, not only video but also microphone input or the like may be used to analyze shouts, cheers, applause, etc., and perform weighting in comparison with the music sequence. Specifically, for example, the excitement of the place may be evaluated by the size of the applause sound immediately after entering the interlude immediately after one chorus. In the case of evaluation, instead of comparing / verifying within one musical piece, a change in the immediately preceding musical piece and the same karaoke box / user may be considered. In other words, by introducing relative results, it becomes easier to grasp the “field atmosphere”.
(11) In the above-described embodiment, the case where a singer's song is scored is described as an example. However, the present invention is not limited thereto, and the performance of a person who plays an instrument may be scored. As described above, the “voice” in the present invention includes various sounds such as a voice generated by a person and a performance sound of a musical instrument.
(12) In the above-described embodiment, the control unit 11 corrects the scoring result in the correction mode as shown in FIG. 2, but the scoring correction mode is not limited to this. If you're laughing, you can set the score to "120%", if you're "depressed", you can set the score to "80%", etc. There may be. In short, any mode may be used as long as the viewer's behavior is reflected in the scoring result.
(13) In the above-described embodiment, the correction mode is specified with reference to the table stored in the correspondence storage area 122. However, the correction mode specifying method is not limited to this. For example, the viewer's behavior may be added to the scoring result using a predetermined algorithm, and any method may be used as long as the viewer's behavior is added to the scoring result.
(14) In the embodiment described above, the karaoke apparatus 10 has realized all the functions according to the embodiment. In contrast, two or more devices connected via a network may share the above functions, and a system including the plurality of devices may realize the karaoke device 10 according to the embodiment. For example, a terminal device including a microphone, a speaker, and a camera and a dedicated computer device having a scoring function may be configured as a system connected via a network.
(15) The program realized by the control unit 11 of the karaoke apparatus 10 described above is provided in a state of being recorded on a recording medium such as a magnetic tape, a magnetic disk, a flexible disk, an optical recording medium, a magneto-optical recording medium, a RAM, or a ROM. Can do. It is also possible to download to the karaoke apparatus 10 via a network such as the Internet.
