<First embodiment>
The karaoke apparatus according to the first embodiment will be described with reference to FIGS.

== Karaoke device ==
The karaoke apparatus 1 is an apparatus for performing karaoke performance and singing karaoke by a user. The karaoke apparatus 1 is installed in each room (karaoke room) of a karaoke store, for example. The karaoke apparatus 1 has a scoring function for evaluating a karaoke singing by a user and presenting a scoring result (details will be described later).

  As shown in FIG. 1, the karaoke apparatus 1 includes a karaoke body 10, a speaker 20, a display device 30, a microphone 40, and a remote control device 50.

  The karaoke main body 10 performs various controls related to karaoke performance and karaoke singing, such as performance control of the selected karaoke music, display control of lyrics and background images, and processing of audio signals input through the microphone 40. 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. The microphone 40 is configured to convert the singing voice of the user into an analog 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.

  Here, the microphone 40 according to the present embodiment is also used as a “sound collection unit” capable of collecting conversation voices of all users within a predetermined range. The predetermined range is a range in which conversation sound can be collected by the sound collection unit. For example, the inside of the karaoke room where the karaoke apparatus 1 is installed is an example of “within a predetermined range”. The microphone 40 collects conversation voices exchanged in the karaoke room before karaoke singing is started.

  The microphone 40 outputs the collected conversation voice (conversation voice data) to the karaoke body 10. Note that the sound collection unit may be provided separately from the microphone 40. Also, a plurality of sound collecting units may be provided.

== Karaoke body 10 ==
As shown in FIG. 2, the karaoke body 10 according to the present embodiment includes a storage unit 10a, a communication unit 10b, an input unit 10c, and a control unit 10d. Each component is connected to the bus B via an interface (not shown).

[Storage unit, communication unit, input unit]
The storage unit 10a is a large-capacity storage device that stores various data such as music data for performing a karaoke performance. The communication unit 10b provides an interface for performing communication between the karaoke body 10 and other components of the karaoke apparatus 1. The input unit 10c has a configuration for the user to input various instructions. Various instructions can be input by selecting various icons displayed on the display screen of the display device 30 or the remote control device 50. In this case, the display device 30 and the remote control device 50 function as the input unit 10c.

[Control unit]
The control unit 10d performs various controls in the karaoke device 1. The control unit 10d includes a CPU and a memory (both not shown). The CPU realizes various functions by executing a program stored in the memory. In the present embodiment, when the CPU executes the program stored in the memory, the control unit 10d functions as the extracting unit 100, the determining unit 200, the scoring unit 300, the correcting unit 400, and the presenting unit 500.

(Extraction means)
The extraction unit 100 extracts voiceprint data of each user from the collected conversation voice.

  A known technique can be used as a method for extracting voiceprint data from a conversation voice. Also, in the case where there are a plurality of users, a method of separating the voice of each user from the conversation voice collected by one sound collection unit is also known in the art (for example, Mitsubishi Electric Corporation HP “http: //www.mitsubishielectric.co.jp/news/2017/0524-e.html ”).

  As a specific example, it is assumed that the general manager A and the employee B (no position) of X Corporation entertain the karaoke room at the second party after receiving the business managers of the general managers C and D of Y Corporation. In this case, the manager A, the employee B, the manager C, and the manager D correspond to the user of the karaoke apparatus 1.

  The microphone 40 collects conversation voice from the time when each user enters the karaoke room, and outputs the voice to the extraction means 100. The extracting means 100 extracts voiceprint data of each user from the conversation voice. In this example, since there are four users, usually four voiceprint data (voiceprint data V1 to voiceprint data V4) are extracted. In addition, the karaoke apparatus 1 cannot identify which user the extracted voiceprint data is.

(Determining means)
The determining means 200 determines the order of each voiceprint data based on the collected conversation voice, and stores the information of the order in association with each voiceprint data.

  In the present embodiment, the determining means 200 determines the order based on honorific information obtained by processing the collected conversational voice. The honorific information is information corresponding to the honorific used by each user in the conversation. For example, honorific information is classified into three categories (respect, humble, polite) and five categories (respect, humble, polite, Polite words, beautifying words). The “order” in the present embodiment is based on the position and position. For example, a user with a high rank may be a person with a higher position or a party to be entertained (entertained party).

  Known methods can be used to obtain honorific information and determine the order.

  As a specific example, the determining unit 200 generates text data by performing voice recognition processing on one conversation voice (see Japanese Patent Application Laid-Open No. 2014-026603). The deciding means 200 detects a honorific word from the textual conversation voice, and calculates a ratio of the number of characters of the honorific character to the total number of characters as a score.

  For example, if the text conversation voice is "always overwhelmed", the total number of characters is 18 characters, and the number of honorific words ("o" and "ori") is 5 characters in total. Therefore, the determining means 200 calculates a score of (5/18) × 100 = 27.82 (point). On the other hand, when the textual conversation voice is “No, this is not it,” the number of honorific words is zero. In this case, the determining unit 200 calculates a score of 0 (point) for the conversation voice.

  The determining means 200 calculates a score for each voiceprint data. When there are a plurality of conversation voices for one voiceprint data, the determination unit 200 calculates a score based on the number of characters of all conversation voices and the number of characters of all honorific words.

  The deciding means 200 decides the order of the voiceprint data in the descending order of the score, that is, in the descending order of the use of honorifics.

  FIG. 3 is a diagram showing the score for each voiceprint data calculated in the present embodiment and the determined order. In FIG. 3, the score corresponding to the voiceprint data V1 is 16 (points), the score corresponding to the voiceprint data V2 is 38 (points), the score corresponding to the voiceprint data V3 is 10 (points), and the score corresponding to the voiceprint data V4. The score is 18 (points). The determining unit 200 determines the order of the voiceprint data V3, the voiceprint data V1, the voiceprint data V4, and the voiceprint data V2 in ascending order of the score of the voiceprint data.

  The method for calculating the score is not limited to the above example. For example, the determining means 200 may calculate the ratio of the number of honorific words in the total number of characters as a score. For example, if the text-based conversational voice is “always overwhelmed”, the determination means 200 determines (2 A score of (/18)×100=11.11 (point) is calculated. Further, the determining means 200 distinguishes and detects the classification of honorific words, and refers to a table weighted for each classification (for example, respectful word: 1.5, humble word: 1.3, polite word 1.0), and scores. May be calculated.

  The determining means 200 stores the information of the determined order in the storage unit 10a in association with each voiceprint data. In the example of FIG. 3, the determining unit 200 links the voiceprint data V3 with the rank “1st”, the voiceprint data V1 with the rank “2nd”, and the voiceprint data V4 with the rank “3rd”. The voiceprint data V2 is stored in the storage unit 10a in association with the rank “fourth”.

(Scoring method)
The scoring means 300 evaluates the karaoke singing by the user and obtains a scoring result. Specifically, the scoring unit 300 scores the singing voice data extracted from the singing voice of the user based on at least one of a pitch, a volume, and a singing technique. The scoring result can be obtained, for example, as a specific numerical value (a numerical value with a perfect score of 100).

  For the evaluation of the karaoke singing, a known technique can be used. For example, the scoring unit 300 extracts singing voice data such as pitch (pitch) data and volume data from a singing voice signal input from the microphone 40, and compares the extracted singing voice data with reference data of a song that has performed karaoke singing. , Scoring value can be obtained. The scoring unit 300 outputs the obtained scoring result to the correcting unit 400.

(Correction means)
When a certain user sings a karaoke song, the correction means 400 specifies voiceprint data that matches the voiceprint authentication data extracted from the singing voice of the certain user, and associates the voiceprint data with the specified voiceprint data. The scoring result of the karaoke singing of the certain user is corrected based on the information of the order.

  The voiceprint authentication data is voiceprint data extracted from a singing voice of a user who sings a karaoke song. For example, in the above example, assume that the manager A, the employee B, the manager C, and the manager D enter the karaoke room and then sing karaoke in order. The extracting unit 100 extracts voiceprint data of a certain user as voiceprint authentication data by analyzing a singing voice of a user who sings karaoke at the start of the performance of the karaoke music.

  The correction of the scoring result is performed based on the correction information set in advance and stored in the storage unit 10a. The correction information indicates, for example, a specific numerical value such as “Add 10 points to the scoring result of the first-ranked user”, or “increase the scoring result of the first-ranked user by 10%”. ". However, if there is an upper limit (for example, 100 points) of the scoring result, it is preferable to adjust the score so as not to exceed the upper limit. Further, instead of correcting only the scoring result of the first-ranked user, correction may be made to add a difference in points according to the rank or to deduct points depending on the rank. For example, correction information such as “ranking first place is +10 points, ranking second place is +5 points, ranking third place is ± 0 point, and ranking fourth place is −5 points” may be used. In addition, when the scoring result is deducted, the scoring result may be low even though the actual karaoke singing sounds good. When such a situation occurs, there is a possibility that the scoring result may be doubted (a possibility that the scoring result is operated). Therefore, when the scoring value by the scoring unit 300 is equal to or more than a certain value (for example, 90 points or more), it is preferable that no deduction is performed even if the order is a point to be deducted.

  The correction unit 400 specifies voiceprint data that matches the voiceprint authentication data from the voiceprint data stored in the storage unit 10a.

  For example, assume that employee B sings karaoke. In this case, the correction means 400 specifies one voiceprint data from the storage unit 10a based on the voiceprint authentication data of the employee B. Here, it is assumed that the voice data V2 shown in FIG. 3 is specified as the voiceprint data of the employee B.

  It is assumed that the employee B finishes the karaoke singing, and the scoring unit 300 calculates “80 points” as the result of the scoring of the karaoke singing of the employee B. The correcting unit 400 corrects the scoring result based on the information of the order linked to the identified one voiceprint data V2 for the scoring result “80 points”. Here, it is assumed that the correction information is “Add 10 points to the scoring result of the first-ranked user”. In this case, according to the example of FIG. 3, the order of the identified one voiceprint data V2 is not the first. Therefore, the correcting unit 400 outputs the result to the presenting unit 500 without correcting the scoring result “80 points”.

  On the other hand, for example, assume that the manager C sings karaoke. In this case, the correction unit 400 specifies one voiceprint data from the storage unit 10a based on the voiceprint authentication data of the manager C. Here, it is assumed that the voice data V3 shown in FIG. 3 has been specified as the voiceprint data of the C section manager.

  It is assumed that the manager C finishes the karaoke singing, and the scoring unit 300 calculates “85 points” as the scoring result of the karaoke singing of the manager C. The correcting unit 400 corrects the scoring result based on the information of the order linked to the identified one voiceprint data V3 for the scoring result “85 points”. Similarly to the above, it is assumed that the correction information is “Add 10 points to the scoring result of the first-ranked user”. In this case, according to the example of FIG. 3, the specified one voiceprint data V3 is ranked first. Accordingly, the correcting unit 400 outputs “95 points” obtained by adding “10 points” to the scoring result “85 points” as the scoring result of the C section manager, and outputs the result to the presentation unit 500.

[Presentation means]
The presenting unit 500 presents the scoring result obtained by the scoring unit 300 or the scoring result corrected by the correcting unit 400 to the user.

  Various methods can be used to present the scoring results. For example, the presentation unit 500 can display the scoring result on the display screen of the display device 30. Alternatively, the presentation means 500 can emit the scoring result via the speaker 20.

== Processing in karaoke device ==
Next, a specific example of processing in the karaoke apparatus 1 according to the present embodiment will be described with reference to FIG. FIG. 4 is a flowchart illustrating a processing example in the karaoke apparatus 1.

  After the user enters the karaoke room, the microphone 40 collects the conversation voices of all the users in the karaoke room (collection of conversation voices, step 10).

  The extraction means 100 extracts voiceprint data of each user from the conversation voice collected in step 10 (voiceprint data extraction; step 11).

  The deciding means 200 decides the order of each voiceprint data based on the conversation voice collected in step 10 (determines the order of voiceprint data, step 12).

  The deciding means 200 stores the information on the sequence determined in step 12 in association with the voiceprint data extracted in step 11 in the storage unit 10a (storage of the sequence information and voiceprint data; step 13).

  Here, when a certain user sings a karaoke song (in the case of Y in step 14), the microphone 40 collects the singing voice of the certain user (collection of singing voice; step 15). The extracting means 100 extracts voiceprint data (voiceprint authentication data) of a user from the singing voice (extraction of voiceprint authentication data, step 16).

  The correction means 400 specifies voiceprint data that matches the voiceprint authentication data extracted in step 16 from the voiceprint data stored in step 13 (voiceprint data specification, step 17).

  The scoring means 300 evaluates the karaoke singing of a certain user and obtains a scoring result (scoring of karaoke singing. Step 18).

  The correction means 400 corrects the scoring result of a certain user's karaoke singing obtained in step 18 based on the information of the order linked to the voiceprint data specified in step 17 (correction of the scoring result). Step 19).

  The presentation means 500 presents the scoring result corrected in step 19 (presentation of the scoring result. Step 20).

  As described above, the karaoke apparatus 1 according to the present embodiment has a scoring function of evaluating a karaoke singing by a user and presenting a scoring result. The karaoke apparatus 1 includes a microphone 40 that can collect conversation voices of all users within a predetermined range, and a control unit 10d that controls the karaoke apparatus 1. The control unit 10d extracts the voiceprint data of each user from the collected conversation voices, determines the rank of each voiceprint data based on the collected conversation voices, and stores the information of the ranks in each voiceprint. Determining means 200 for storing in association with data, when a certain user sings karaoke, specifies voiceprint data that matches voiceprint authentication data extracted from the singing voice of the certain user, and specifies the specified voiceprint It functions as a correction unit 400 that corrects the scoring result of the karaoke song of the certain user based on the information of the order linked to the data.

  According to such a karaoke apparatus 1, when a certain user sings karaoke, the scoring result can be corrected according to the automatically determined order of voiceprint data. In this case, since a partner with a higher rank (for example, an entertainment partner) tends to obtain a better scoring result, the place can be excited using the scoring function. That is, according to the karaoke apparatus 1 according to the present embodiment, the scoring result of the karaoke song can be corrected without being noticed by the user who has performed the karaoke song.

  Further, the determining means 200 according to the present embodiment is characterized in that an order is determined based on a score calculated based on honorific word information obtained by processing collected speech sounds. As a general business manner, it is preferable to use honorifics for those who are superior. Therefore, by determining the rank using the score calculated based on such honorific information, the rank of the voiceprint data can be determined more accurately.

<Second embodiment>
Next, a karaoke apparatus according to a second embodiment will be described with reference to FIGS. In the present embodiment, an example will be described in which the order of the voiceprint data is determined using the title information of each user included in the conversation voice. Note that a detailed description of the same configuration as that of the first embodiment is omitted.

(First storage means)
As shown in FIG. 5, a part of the storage area of the storage unit 10a in the present embodiment functions as a first storage unit 600. The first storage unit 600 stores a title of honor score table in which the title of the user is associated with a predetermined score. A title is a suffix ("san", "sama", "kun", etc.) that a person attaches to a name that is used with respect and respect for the other person, or the word itself. It is a pronoun to express (such as "manager" or "teacher").

  A predetermined value is associated with each score for each title. Here, of the titles, words that the upper one has a higher tendency to use for the lower ones ("kun", "chan", etc.) and words that the lower ones have a high tendency to use for the upper ones ("san", " "). In the present embodiment, the score is set high for words in which the upper one is more likely to use the lower one among the titles, and lower for words that the lower one is more likely to use for the upper one.

  FIG. 6 is an example of the honorific score table. In this example, the table is configured such that the scores become lower in the order of “sama”, “san”, “kun”, and “chan”.

(Determining means)
The determining unit 200 according to the present embodiment determines the order based on the scores calculated based on the honorific information and the honorific score table obtained by processing the collected speech sounds.

  As a specific example, it is assumed that the manager A visits his favorite karaoke snack with the employee B, referred to as a reflection meeting of the entertainment of the company Y. In this karaoke snack, a plurality of microphones 40 are provided for one karaoke body 10. Each microphone can communicate with the karaoke body 10. At least one microphone 40 is placed on each table of the karaoke snack. The microphone 40 collects conversation voice near the table where the microphone is placed. The “predetermined range” in the present embodiment corresponds to the vicinity of the table where the microphone 40 is placed.

  The deciding unit 200 detects the title information included in one conversation voice by performing voice recognition processing on the conversation voice. The deciding means 200 applies the detected title information to the title title table, and obtains a score for one conversational voice. The deciding means 200 sums up the scores for each voiceprint data, and decides the order according to the totaled scores.

  For example, as a result of processing conversation voices of the manager A and the employee B, the voiceprint data Va includes the title “Sama” once, “San” twice, “Kun” 12 times, and “Chan” 3 times. It was assumed that The determining means 200 obtains the total score “88 points” by multiplying the score for each title by referring to the title list and multiplying the multiplied score for each title. On the other hand, it is assumed that the voiceprint data Vb includes the title “Sama” once, “San” 10 times, “Kun” twice, and “Chan” 0 times. The determining means 200 obtains the total score “41 points” by multiplying the score for each title by referring to the title table and multiplying the multiplied score for each title. In this case, the determining means 200 determines the order of the voiceprint data Va as “first” and the order of the voiceprint data Vb as “second” (see FIG. 7). The method for calculating the score is not limited to the above example. For example, the determining means 200 may compare the total of the scores for each honorific title by the number of honorific titles. Specifically, the voiceprint data Va includes 1 + 2 + 12 + 3 = 18 times in all, and when the total score is “88 points”, the determining unit 200 calculates the score as 88/18 = 4.89 points. I do. In addition, the voiceprint data Vb includes a total of 1 + 10 + 2 + 0 = 13 times for the honorific title, and when the total score is “41 points”, the determining unit 200 calculates the score as 41/13 = 3.15 points. Then, by comparing the calculated scores, the determination unit 200 can determine the rank of the voiceprint data Va as “1st” and the rank of the voiceprint data Vb as “2nd”.

== Processing in karaoke device ==
Next, a specific example of processing in the karaoke apparatus 1 according to the present embodiment will be described with reference to FIG. FIG. 8 is a flowchart illustrating a processing example in the karaoke apparatus 1. The first storage unit 600 in the present embodiment stores a title of honorific score table.

  After the user enters the karaoke room, the microphone 40 collects the conversation voices of all the users in the karaoke room (collection of conversation voices, step 30).

  The extracting means 100 extracts voiceprint data of each user from the conversation voice collected in step 30 (voiceprint data extraction; step 31).

  The determining means 200 determines the order of each voiceprint data based on the title calculated based on the title information and the title table obtained by processing the conversational voice collected in step 30 (based on the title information and the like). The order of the voiceprint data is determined (step 32).

  The determining means 200 stores the information of the sequence determined in step 32 in association with the voiceprint data extracted in step 31 in the storage unit 10a (storage of the sequence information and voiceprint data; step 33).

  The processing after step 34 is the same as the processing after step 14 in the first embodiment, and a detailed description thereof will be omitted.

  As described above, the karaoke apparatus 1 according to the present embodiment includes the first storage unit 600 that stores the title of the title in which the title of the user is associated with the predetermined score. The rank is determined based on the title calculated based on the title information and the title table obtained by processing the spoken voice. By using the title information included in the conversation voice in this way, the order can be determined more reliably.

<Third embodiment>
Next, a karaoke apparatus according to a third embodiment will be described with reference to FIGS. In the present embodiment, an example will be described in which the rank of voiceprint data is determined using the seating position of each user. Note that a detailed description of the same configuration as the first embodiment or the second embodiment is omitted.

  The sound collection unit according to the present embodiment is a plurality of directional microphones provided at each user's seating position.

  FIG. 9 is a diagram showing the inside of the karaoke room R in which the karaoke apparatus 1 is installed. The karaoke room R is a so-called “VIP room” and is a room suitable for special occasions such as entertainment. In the karaoke room R, along with the karaoke apparatus 1, five seats (seats S1 to S5), two tables (tables T1, T2), and one display D are installed. In the example of FIG. 9, the display device 30 corresponds to the display D installed on the wall of the karaoke room R.

  In the example of FIG. 9, directional microphones M1 to M5 are respectively installed near each seat. The directional microphone can collect only the conversation voice of the user sitting on the seat.

(Second storage means)
As shown in FIG. 10, a part of the storage area of the storage unit 10a in the present embodiment functions as the second storage unit 700. The second storage unit 700 stores a seating position score table in which a user's seating position within a predetermined range is associated with a predetermined score.

  The seating position score table is provided for each predetermined range. In the example of FIG. 9, the karaoke room R corresponds to the predetermined range.

  FIG. 11 shows a seating position score table in the karaoke room R. As shown in FIG. 9, seats S1 to S5 are installed in the karaoke room R. Here, in general business manners, it is preferable that a person with a high rank sits in a seat far from the entrance of the room. Therefore, the score is set higher (in the order of 40 points, 30 points, 20 points, 10 points, and 0 points) in order from the seat far from the entrance of the karaoke room R (in the order of seats S1, S2, S3, S4, S5). The table is configured.

(Determining means)
The determining means 200 according to the present embodiment determines the order based on the seat position corresponding to the collected conversation voice and the score calculated based on the seat position score table.

  As a specific example, it is assumed that the manager A and the employee B (no position) of X Co., Ltd. entertain the karaoke room R at the second party after receiving the business managers of the managers C and D of Y Corporation. Further, assume that the manager C sits on the seat S2, the manager D sits on the seat S3, the manager A sits on the seat S4, and the employee B sits on the seat S5. In this case, the manager A, the employee B, the manager C, and the manager D correspond to the user of the karaoke apparatus 1.

  The directional microphones M <b> 1 to M <b> 5 collect the conversation voice from the time when each user takes a seat, and output the voice to the extraction unit 100. The extracting means 100 extracts voiceprint data for each seat from the conversation voice. In this example, since there are four users, usually four voiceprint data are extracted. Note that the karaoke apparatus 1 cannot identify who is seated in each seat and which user's voiceprint data is the extracted voiceprint data.

  Here, the directional microphone and the seat correspond one-to-one. Therefore, for example, the voiceprint data V11 extracted from the conversation voice collected by the directional microphone M1 can be determined to be the voiceprint data of the user having the highest rank. In this example, voiceprint data V12 to V15 are extracted from the conversation voice collected by the directional microphones M2 to M5.

  The deciding unit 200 applies the seating position of each user (that is, the installation position of each directional microphone) to the seating position score table, and calculates a score for each collected voiceprint data. The determining means 200 determines the order according to the score for each voiceprint data.

  For example, the voiceprint data V12 is extracted from a conversation voice collected by the directional microphone M2 installed at the seat position S2. Therefore, the determining means 200 calculates a score “30 points” from the seat position S2 and the seating position score table for the voiceprint data V12. Similarly, the voice print data V13 is extracted from the conversation voice collected by the directional microphone M3 installed at the seat position S3. Therefore, the determination means 200 calculates a score “20 points” for the voiceprint data V13 from the seat position S3 and the seating position score table. The voiceprint data V14 is extracted from the conversation voice collected by the directional microphone M4 installed at the seat position S4. Therefore, the determining means 200 calculates a score “10 points” for the voiceprint data V13 from the seat position S4 and the seating position score table. The voiceprint data V15 is extracted from the conversation voice collected by the directional microphone M5 installed at the seat position S5. Therefore, the determining means 200 calculates a score “0” for the voiceprint data V15 from the seat position S5 and the seating position score table.

  In this case, the determining unit 200 determines that the rank of the voiceprint data V12 is “1st”, the rank of the voiceprint data V13 is “2nd”, the rank of the voiceprint data V14 is “3rd”, and the rank of the voiceprint data V15 is “4th”. (See FIG. 12).

== Processing in karaoke device ==
Next, a specific example of processing in the karaoke apparatus 1 according to the present embodiment will be described with reference to FIG. FIG. 13 is a flowchart illustrating a processing example in the karaoke apparatus 1. In the present embodiment, it is assumed that a plurality of users enter the karaoke room R shown in FIG. 9 and each of them takes a seat. The second storage unit 700 in the present embodiment stores a seating position score table.

  After the user is seated, each directional microphone collects the conversation voice of the user for each seat (collects conversation voice for each seat. Step 50).

  The extracting means 100 extracts voiceprint data of each user from the conversation voice collected in step 50 (extraction of voiceprint data; step 51).

  The determining means 200 determines the order of each voiceprint data based on the seat position corresponding to the conversation voice collected in step 50 and the score calculated based on the seat position score table (the voiceprint data of the voiceprint data is determined based on the seat position and the like). Determine the order, step 52).

  The determining means 200 stores the information of the order determined in step 52 in association with the voiceprint data extracted in step 51 in the storage unit 10a (storage of information of the order and voiceprint data; step 53).

  Since the processing after step 54 is the same as the processing after step 14 in the first embodiment, a detailed description is omitted.

  As described above, the karaoke apparatus 1 according to the present embodiment includes the second storage unit 700 that stores the seating position score table in which the user's seating position within the predetermined range is associated with the predetermined score. The sound section is a plurality of directional microphones M1 to M5 provided at the seating positions of the respective users. The deciding means 200 decides the order based on the seat position corresponding to the collected conversation voice and the score calculated based on the seat position score table. By using the seating position corresponding to the conversation voice in this way, the order can be determined more reliably.

  In the above embodiment, an example is described in which a directional microphone installed in each seat is used, but the present invention is not limited to this. For example, conversation sounds of a plurality of users are collected as stereo signals using two microphones. The karaoke apparatus 1 may determine the position (seated seat) of each user by separating the sound source of the collected conversation sound and detecting the localization and volume of each conversation sound. Known techniques can be used for sound source separation and localization and volume detection of conversational voice.

  Further, the determining means 200 may acquire gender information from the collected conversation voice using a known technique, and determine the order together with the information on the seat position. For example, if a certain user is sitting next to the opposite sex, the certain user is receiving a companion, and can be regarded as a side to be treated, that is, a user with a high rank.

<Others>
The first to third embodiments can be implemented in appropriate combinations. For example, for each voiceprint data, the determining unit 200 detects a honorific word from the text-based conversational voice, and calculates a score based on the ratio of the number of honorific words to the total number of characters (see the first embodiment) and the detected honorific information (Second embodiment), and a score calculated based on the seating position and the seating position score table corresponding to the collected conversational voice (third embodiment). A score may be obtained, and a ranking may be determined based on the total score.

  The above embodiments have been presented by way of example and do not limit the scope of the invention. The above configurations can be appropriately combined and implemented, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. The above-described embodiments and their modifications are included in the scope and gist of the invention, and are also included in the invention described in the claims and equivalents thereof.
