<First embodiment>
A car-mounted karaoke device according to a first embodiment will be described with reference to FIGS.

== vehicle ==
The vehicle 1 is an automobile such as a sightseeing bus. As shown in FIG. 1, the vehicle 1 is equipped with an acceleration sensor S and a karaoke device K.

== Acceleration sensor ==
The acceleration sensor S is a sensor that detects acceleration acting on the vehicle 1. As the acceleration sensor S, for example, a known sensor such as an analog type three-axis acceleration sensor that detects acceleration in three axial directions orthogonal to each other can be used.

  The analog type three-axis acceleration sensor has three output terminals corresponding to three detection axes, respectively. From each of the three output terminals, a voltage indicating an acceleration acting in an axial direction corresponding to the output terminal. The signal is output to the karaoke apparatus K main body.

  For example, when the vehicle 1 is traveling on a road, vertical acceleration due to unevenness of the road surface and horizontal acceleration according to the acceleration / deceleration operation act on the vehicle 1. Further, when the vehicle 1 runs on a curve or the like, a centrifugal force acts on the vehicle 1. Further, when the vehicle 1 includes an engine as a drive source, acceleration due to vibration of the engine acts. The acceleration sensor S detects these components and outputs them to the karaoke apparatus K.

  The acceleration sensor S detects the acceleration while at least the karaoke singing is performed using the karaoke apparatus K.

== Karaoke device ==
The karaoke device K is a device that allows a user who gets on the vehicle 1 to sing karaoke in the vehicle. As shown in FIG. 2, the karaoke apparatus K includes a karaoke body 10, a speaker 20, a display device 30, a microphone 40, and a remote control device 50. The karaoke device K according to the present embodiment is equivalent to an “on-board karaoke device”.

  The speaker 20 is configured to emit sound based on a sound emission signal from the karaoke body 10. The display device 30 is configured to display a video or an image on a screen based on a signal from the karaoke body 10. Further, the display device 30 according to the present embodiment functions as a “display unit” that displays an evaluation (described later) of the karaoke song. The microphone 40 is configured to convert a user's singing voice (voice input to the microphone 40) into an analog voice signal (singing voice signal) and input the analog voice signal to the karaoke body 10. The remote control device 50 is a device for performing various operations on the karaoke body 10. The user can use the remote control device 50 to search for a song for which karaoke singing is desired, select a song (reserve), and the like. Icons and the like for inputting various operation instructions are displayed on the display screen of remote control device 50.

  The karaoke body 10 performs various controls relating to karaoke singing, such as karaoke performance control of the selected music, display control of lyrics and background images, and processing of audio signals input through the microphone 40. As shown in FIG. 2, the karaoke main body 10 includes a control unit 11, a communication unit 12, a storage unit 13, a sound 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 and a memory (not shown). The CPU realizes various control functions by executing an operation program stored in the memory. The memory is a storage device that stores a program to be executed by the CPU and temporarily stores various information when the program is executed.

  The communication unit 12 provides an interface for connecting the karaoke body 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. The storage unit 13 stores, for example, a plurality of music data used in the karaoke apparatus K. The music data is provided with a music ID (identification information) for specifying each music. The music data includes accompaniment data for performing a karaoke performance, reference data used for karaoke singing evaluation, lyrics telop data, background image data, and music attribute information (song name, singer name, lyric / composer name, genre) Etc.).

  The sound processing unit 14 controls the karaoke performance of the music and processes the singing voice signal input through the microphone 40 based on the control of the control unit 11. The display processing unit 15 performs various display-related processes on the display device 30 and the remote control device 50 based on the control of the control unit 11. For example, the display processing unit 15 causes the display device 30 to display a video in which lyrics telops and various icons are superimposed on a background video during a karaoke performance. Alternatively, the display processing unit 15 displays various icons for operation input on the display screen of the remote control device 50. The operation unit 16 includes a panel switch, a remote control receiving circuit, and the like, and sends an operation signal such as a music selection signal or a performance stop signal to the control unit 11 in response to a user's operation of the panel switch of the karaoke apparatus K or the remote control apparatus 50. Output. The control unit 11 detects an operation signal from the operation unit 16 and executes a corresponding process.

  The user who has boarded the vehicle 1 selects a karaoke song via the remote control device 50. The karaoke body 10 causes the display device 30 to display lyrics and a background image while performing the karaoke performance of the selected music. The user can sing a karaoke song via the microphone 40 while referring to the displayed lyrics.

  Note that a vehicle speaker that is installed in the vehicle 1 in advance may be used instead of the speaker 20. Further, a car navigation device mounted on the vehicle may function as a substitute for the display device 30 or the remote control device 50.

== Karaoke body ==
As shown in FIG. 3, the karaoke body 10 in the present embodiment includes an evaluation unit 100, an acquisition unit 200, a correction unit 300, and a display control unit 400. The evaluation unit 100, the acquisition unit 200, the correction unit 300, and the display control unit 400 are realized by the CPU of the control unit 11 executing a program stored in a memory.

[Evaluation Department]
The evaluation unit 100 obtains an evaluation of the karaoke singing based on the singing voice of the karaoke singing.

  The evaluation of the karaoke song can be obtained, for example, as a score value. A well-known method can be used to obtain a score based on karaoke singing. For example, the evaluation unit 100 obtains a score by extracting singing voice data such as pitch (pitch) data and volume data from a singing voice signal input from the microphone 40 and comparing the singing voice data with reference data of the music. . The scoring value may be a specific numerical value (0 to 100 points) or a rank (for example, a 10-level evaluation of A to J) classified into several categories.

  In the present embodiment, the evaluation unit 100 evaluates the karaoke singing for each singing section (for example, the first A melody, the first B melody, the first rust, the second A melody...). The evaluation of the karaoke singing in each singing section may be performed each time the karaoke performance in each singing section ends, or may be performed after the karaoke performance in all singing sections ends.

  The evaluation may include singing expressiveness such as accuracy, stability, and singing technique of the pitch. In addition, the evaluation unit 100 may calculate a score value in consideration of these evaluations.

[Acquisition unit]
The acquisition unit 200 acquires travel information according to the output of the acceleration sensor S.

  The travel information is information corresponding to a specific movement of the vehicle 1. The specific movement is, for example, shaking or vibration of the vehicle 1 accompanying running on an uneven road, starting or stopping of the vehicle, running on a curve, or changing directions of the vehicle 1.

  For example, if the vehicle 1 vibrates while singing a karaoke song, the user's voice may tremble. In addition, if the user travels on a curve while singing a karaoke song, the user who sings the karaoke song may lean due to centrifugal force. In any case, it becomes a factor that hinders karaoke singing in the vehicle 1. That is, the travel information is information that may adversely affect the evaluation of the karaoke singing.

  The acquisition unit 200 acquires travel information based on the output from the acceleration sensor S. For example, the acquisition unit 200 acquires a factor (type) of change in acceleration and a degree (level) of change in acceleration as the traveling information by filtering a signal output from the acceleration sensor S. Factors that have changed the acceleration are, for example, “vibration”, “shake”, “turning (curve running or direction change)”, “start”, and “stop”. The degree of change in acceleration is, for example, “small scale (acceleration change is 1 to 10%)”, “medium scale (acceleration change is 11% to 30%)”, or “large scale (acceleration change is 31%). Above) ”).

  For example, it is assumed that the vehicle 1 has traveled on an uneven road surface. In this case, the acceleration sensor S inputs to the karaoke body 10 a signal indicating the acceleration due to the unevenness of the road surface. The acquisition unit 200 can acquire, for example, traveling information such as “vibration” and “medium scale” by filtering this signal.

  The acquisition unit 200 outputs the acquired traveling information to the correction unit 300. The timing at which the travel information is output varies. For example, the acquisition unit 200 temporarily stores the acquired traveling information in the memory of the control unit 11 sequentially. Then, after the end of the karaoke singing, the acquisition unit 200 reads the running information stored in time series from the memory and outputs the running information to the correction unit 300. Alternatively, the acquisition unit 200 may output the traveling information to the correction unit 300 each time the traveling information is acquired.

[Correction unit]
The correction unit 300 corrects the evaluation based on the travel information.

  Various methods can be used to correct the evaluation. For example, when the evaluation is obtained as a scoring value, the correction unit 300 can correct the evaluation by adding a correction value based on the traveling information to the scoring value. Alternatively, the correction unit 300 can correct the evaluation by multiplying the scoring value by a correction coefficient based on the travel information. The correction value and the correction coefficient may use a preset correction table or may be calculated using a predetermined conversion formula.

  In the correction table, for example, as shown in FIG. 4, 15 types of correction values are set according to the factors (five types) of the acceleration change and the degree of the change of the acceleration (three levels).

  The correction unit 300 obtains one correction value by applying the traveling information output from the obtaining unit 200 to the correction table, and corrects the evaluation (scoring value) obtained by the evaluation unit 100.

  For example, it is assumed that the evaluation unit 100 obtains a value of “91.2 points” as a score value in the singing section D1 of the song X of the user A. On the other hand, it is assumed that the acquisition unit 200 acquires “vibration” and “small scale” as travel information while the user A is singing karaoke in the singing section D1.

  In this case, the correction unit 300 acquires a correction value “+1” corresponding to “vibration” / “small” with reference to the correction table in FIG. The correction unit 300 obtains the scoring information “92.2 points” in the singing section D1 by adding the correction value “+1” to the scoring value. The correction unit 300 corrects the score value for each singing section. When the traveling information is not acquired by the acquiring unit 200, the correcting unit 300 performs processing with the correction value “0” (that is, does not perform any special correction).

  FIG. 5 shows the score values for each singing section, running information for each singing section, the corrected scoring values, and the average values of the scoring values (before and after the correction) obtained by performing karaoke singing of song X by the user A. An example is shown. In this example, since the traveling information has not been acquired for the singing sections D3 and D8, the scoring value has not been corrected.

  In addition, when the range of the scoring value is 0 to 100 points, adding the correction value to the scoring value may exceed 100 points (full score). In this case, the correction unit 300 may limit the scoring value after correction to 100 points for a singing section exceeding 100 points, or may set the value exceeding 100 points as the scoring value of the singing section as it is. . However, in the latter case, the correction unit 300 preferably limits the average of the scoring values to 100 points.

[Display control unit]
The display control unit 400 displays the corrected evaluation on a display unit (display device 30).

  The display control unit 400 can display the corrected evaluation in various display modes. When the evaluation as shown in FIG. 5 is obtained, the display control unit 400 displays, for example, only the average value (87.34 points) of the corrected scoring values. Alternatively, the display control unit 400 causes the average value of the corrected scoring values (87.34 points) and the average value of the scoring values before correction (79.96 points) to be displayed side by side. Alternatively, the display control unit 400 may display the corrected score values for each of the singing sections D1 to D8 side by side. When the corrected score value is displayed for each singing section, there may be uncorrected singing sections (singing sections D3 and D8 in the example of FIG. 5). In this case, the display control unit 400 causes the original scoring value to be displayed as it is for the uncorrected scoring value.

  Further, the display control unit 400 may display the corrected evaluation and the travel information used for the correction in association with each other.

  For example, in the example of FIG. 5, the singing section D1 gives “+1 point” to the scoring value in consideration of the influence of vibration, and the singing section D2 takes “+2 points” to the scoring value in consideration of the influence of vibration. Singing section D4 gives “+15 points” to the scoring value in consideration of the influence of turning, and singing section D5 gives “+1 point” to the scoring value in consideration of the influence of vibration. The singing section D6 is “+10 points” with respect to the scoring value in consideration of the influence of shaking, and the singing section D7 is “+30 points” with respect to the scoring value in consideration of the influence of stoppage.

  In this case, as shown in FIG. 6, the display control unit 400 displays the factor and the correction value as a comment for each corrected singing section, in addition to the average value of the corrected score values.

== Processing in the in-car karaoke device ==
Next, a specific example of processing in the karaoke apparatus K according to the present embodiment will be described with reference to FIG. FIG. 7 is a flowchart illustrating a processing example in the karaoke apparatus K. In this example, the karaoke apparatus K is mounted on the vehicle 1. Then, it is assumed that the user who has boarded the vehicle 1 sings karaoke in the running car using the karaoke apparatus K. Further, in this example, description will be made assuming that some traveling information is acquired during traveling of the vehicle 1.

  The evaluation unit 100 evaluates the karaoke singing based on the singing voice of the karaoke singing (evaluation of the karaoke singing. Step 10).

  The acquisition unit 200 acquires travel information of the vehicle 1 according to the output of the acceleration sensor S (acquisition of travel information, step 11).

  The acquisition unit 200 causes the storage unit 13 to temporarily store the traveling information acquired in Step 11 (storage of traveling information; Step 12).

  After the karaoke singing is completed (Y in Step 13), the correction unit 300 corrects the evaluation based on the traveling information acquired in Step 11 (Evaluation correction; Step 14).

  The display control unit 400 displays the evaluation corrected in step 14 on the display device 30 (display of evaluation. Step 15).

  As described above, the karaoke device K according to the present embodiment is a device mounted on the vehicle 1 for singing karaoke in the vehicle. The karaoke apparatus K includes an evaluation unit 100 that obtains an evaluation of the karaoke singing based on the singing voice of the karaoke singing, and an obtaining unit that obtains traveling information corresponding to a specific movement of the vehicle 1 according to an output of the acceleration sensor S. 200, and a correction unit 300 that corrects the evaluation based on the travel information.

  As described above, when the evaluation (for example, the scoring value) is corrected based on the traveling information, the karaoke singing cannot be successfully performed due to the vibration or shaking of the vehicle 1 or the influence of traveling on a curve. Even so, the evaluation of karaoke singing does not become extremely bad. That is, according to the karaoke apparatus K according to the present embodiment, the karaoke singing can be evaluated in consideration of the running state of the vehicle 1.

  In addition, the karaoke apparatus K has a display control unit 400 that displays the corrected evaluation on the display device 30. The display control unit 400 can display the corrected evaluation and the traveling information used for the correction in association with each other. By performing such a display, the user can visually grasp what kind of traveling information has been used to correct the evaluation.

<Second embodiment>
Next, a car-mounted karaoke device according to a second embodiment will be described with reference to FIGS. In the present embodiment, an example will be described in which the evaluation is corrected in consideration of the emotion of the user in addition to the driving situation. A detailed description of the same configuration as in the first embodiment will be omitted.

  As shown in FIG. 8, the karaoke body 10 according to the present embodiment includes an evaluation unit 100, an acquisition unit 200, a correction unit 300, a display control unit 400, and an emotion analysis unit 500. The evaluation unit 100, the acquisition unit 200, the correction unit 300, the display control unit 400, and the emotion analysis unit 500 are realized by the CPU of the control unit 11 executing a program stored in a memory.

[Sentiment Analysis Department]
The emotion analysis unit 500 analyzes the emotion of the user based on face image data obtained by photographing the face of the user performing the karaoke singing, and acquires emotion data.

  The photographing of the user's face is performed by a photographing device (not shown). The photographing device is a device for photographing the face of a user performing karaoke singing and acquiring a face image (face image data). At least one photographing device is installed in the vehicle 1 on which the karaoke device K is mounted. The photographing device outputs the acquired face image to the karaoke device K. The photographing by the photographing device is performed at an arbitrary timing (for example, for each singing section) during the singing of the karaoke song.

  The processing of emotion analysis using the face image (face image data) can use a known technique. For example, according to “BeesightMARKII” (Arts Aihan Co., Ltd., “Beesight” is a registered trademark), it is possible to analyze six types of emotions from a human face image and obtain parameters for each emotion. Further, according to a convolutional neural network (CNN / ConvNet) described in JP-A-2017-156854, it is possible to obtain a parameter of a specific emotion.

  When receiving the input of the face image data, the emotion analysis unit 500 analyzes the user's face image by using the above-described known technology, and obtains some emotion-related parameters.

  For example, it is assumed that the user feels “anxiety” due to a sudden deceleration while singing karaoke. The emotion analysis unit 500 analyzes the face image taken at that time to obtain a parameter relating to the feeling of “anxiety”. The processing by the emotion analysis unit 500 may be performed each time face image data is input, or may be collectively performed after the karaoke singing.

[Correction unit]
The correction unit 300 according to the present embodiment corrects the evaluation based on the travel information and the emotion data.

  Various methods can be used to correct the evaluation. For example, when the evaluation is obtained as a scoring value, the correcting unit 300 corrects the evaluation by adding a value obtained by multiplying a correction value based on the traveling information by a correction coefficient based on emotion data to the scoring value. Can be. Alternatively, the correction unit 300 can correct the evaluation by multiplying a value obtained by adding the correction value based on the traveling information to the scoring value by a correction coefficient based on the emotion data. The correction value and the correction coefficient may use a preset correction table or may be calculated using a predetermined conversion formula.

  In the correction table for emotion data, for example, as shown in FIG. 9, correction coefficients corresponding to the types of emotion (three types) are set.

  The correction unit 300 obtains one correction value by applying the traveling information output from the obtaining unit 200 to the correction table in FIG. Further, the correction unit 300 obtains one correction coefficient by applying the emotion data obtained by the emotion analysis unit 500 to the correction table in FIG. 9, multiplies the one correction value by the specified correction coefficient, and scores the data. By adding to the value, the evaluation (scoring value) obtained by the evaluation unit 100 is corrected.

  For example, it is assumed that the evaluation unit 100 determines a value of “84.8 points” as a score value in the singing section D2 of the music piece X of the user A. Further, it is assumed that the acquisition unit 200 acquires “vibration” and “medium scale” as travel information while the user A is singing karaoke in the singing section D2. Further, it is assumed that the emotion analysis unit 500 obtains the emotion of “upset” as emotion data when the user A is singing karaoke in the singing section D2.

  In this case, the correction unit 300 acquires the correction value “+2” corresponding to “vibration” / “medium scale” with reference to the correction table in FIG. Further, the correction unit 300 refers to the correction table in FIG. 9 and acquires a correction coefficient “1.1” corresponding to “sway”. The correction unit 300 obtains a new correction value “+2.2” by multiplying the correction value “+2” by the correction coefficient “1.1”. The correction unit 300 obtains the scoring information “87.0 points” in the singing section D2 by adding the new correction value “+2.2” to the scoring value “84.8 points”. The correction unit 300 corrects the score value for each singing section. When emotion data is not acquired by emotion analysis section 500, correction section 300 performs processing with correction coefficient “1.0” (that is, correction based on emotion data is not performed).

  FIG. 10 shows scoring values for each singing section, running information for each singing section, emotion data, corrected scoring values, and average values of the scoring values obtained by performing karaoke singing of song X by the user A. (Before and after). In this example, since no emotion data has been obtained for the singing sections D1, D3, D5, and D8, the scoring value is not corrected based on the emotion data.

== Processing in the in-car karaoke device ==
Next, a specific example of processing in the karaoke apparatus K according to the present embodiment will be described with reference to FIG. FIG. 11 is a flowchart illustrating a processing example in the karaoke apparatus K. In this example, the karaoke apparatus K is mounted on the vehicle 1. Then, it is assumed that the user who got on the vehicle 1 sings a karaoke song in the running vehicle using the karaoke device K. Further, in this example, description will be made assuming that some traveling information is acquired during traveling of the vehicle 1.

  The evaluation unit 100 evaluates the karaoke singing based on the singing voice of the karaoke singing (evaluation of the karaoke singing. Step 20).

  The acquisition unit 200 acquires travel information of the vehicle 1 according to the output of the acceleration sensor S (acquisition of travel information, step 21).

  The acquisition unit 200 causes the storage unit 13 to temporarily store the traveling information acquired in Step 21 (storage of traveling information; Step 22).

  On the other hand, the emotion analysis unit 500 analyzes the emotion of the user based on the face image data obtained by photographing the face of the user performing the karaoke singing, and acquires the emotion data (acquisition of the emotion data. Step 23).

  The emotion analysis unit 500 causes the storage unit 13 to temporarily store the travel information acquired in step 23 (emotion data storage; step 24). Note that the processing of step 21 and step 22 and the processing of step 23 and step 24 may be performed in reverse order, or may be performed in parallel.

  After the karaoke singing is completed (Y in step 25), the correction unit 300 corrects the evaluation based on the traveling information obtained in step 21 and the emotion data obtained in step 23 (correction of evaluation. Step). 26).

  The display control unit 400 displays the evaluation corrected in step 26 on the display device 30 (display of evaluation; step 27).

  As described above, the karaoke apparatus K according to the present embodiment analyzes the emotion of the user based on the face image data obtained by photographing the face of the user performing the karaoke singing, and acquires the emotion data. It has an emotion analysis unit 500, and the correction unit 300 corrects the evaluation based on the travel information and the emotion data.

  If the emotion changes during the karaoke singing according to the driving situation, the evaluation may be adversely affected. In this case, by correcting the evaluation based on the emotion data, it is possible to obtain an evaluation in consideration of the adverse effect.

<Others>
In the above embodiment, an example in which karaoke singing is evaluated or corrected for each singing section has been described, but the unit of evaluation is not limited to this. For example, several singing sections may be evaluated collectively, and the evaluation may be corrected.
