The present invention relates to a karaoke apparatus capable of executing a command for performing a predetermined operation according to a command word input by voice.

Patent Document 1 below describes a karaoke device that has a function of executing a command (operation command) corresponding to the command word to perform a predetermined operation when a predetermined command word (keyword) is voice input from a microphone. Are listed. For example, the command word "Owari" corresponds to the command "Stop playing." When the command word "Owari" is input by voice, the karaoke apparatus executes the command "Stop playing" and stops playing the music.

In a karaoke device having such a function, a command may be executed against the user's will based on the user's karaoke singing voice while a song is being played. For example, if the character string "Owari" is included in the lyrics of a song, the moment the user utters "Owari" as part of the lyrics while singing the song at karaoke, the user will be prompted to "stop playing." It is conceivable that the command will be executed and the karaoke device will stop playing the music against the user's wishes.

In this regard, the karaoke device described in the same document detects the characters forming the command word when a command word is detected from the singing voice at a certain point while the user is performing karaoke singing of a certain song. The string is compared with the lyrics of the song at that point in time, and if they do not match, execute the command corresponding to that command word, and if they match, prohibit execution of the command corresponding to that command word. It has a function.

JP2019-117282A

However, in the karaoke device described in Patent Document 1, if the lyrics of a song include a character string that is aurally similar to a command word, the user utters the string while singing the song. When doing so, the karaoke machine may mistakenly detect a command word similar to the character string. In this case, the character string forming the erroneously detected command word does not match the lyrics of the song at the time when the character string similar to the command word was uttered, so the karaoke device Execute a command. As a result, the karaoke device will operate against the user's wishes.

For example, assume that the command word "stop" corresponds to the command "stop playing." On the other hand, assume that the lyrics of the song include the character string "stock." "Stop" and "Stock" are aurally similar, so when a user says "Stock" while singing the song, the karaoke machine incorrectly detects "Stock" as "Stop". There is a possibility that it will happen. In this case, the lyrics of the song at the time when the user utters "Stock" do not include the string "Stop", so the karaoke machine executes the command "Stop playing" and follows the user's wishes. On the other hand, the performance of the song is stopped.

The present invention has been made in view of the above-mentioned problems, for example, and an object of the present invention is to suppress execution of the command corresponding to the command word even if a command word is erroneously detected during karaoke singing. Our goal is to provide a karaoke device that can do the following.

For example, by operating the remote control device 3, the user can specify a song for karaoke singing, start and stop playing the song, adjust the key and tempo of the song, adjust the volume, etc.

(Voice operation related functions)
The karaoke apparatus 1 has a voice operation function that executes a command and performs a predetermined operation according to a command word that is input by voice through the microphone 5. FIG. 2 shows a command table 31 used to implement the voice operation function and an explanation of each command.

In FIG. 2, a command is an instruction for operating the control unit 8. For example, commands include: start playing a song, stop playing a song, raise the key of the song by a semitone, lower the key of the song by a semitone, increase the tempo of the song by 1 unit, decrease the tempo of the song by 1 unit, etc. There are commands such as increasing the volume by 1 unit and decreasing the volume by 1 unit.

The command word is a keyword for identifying a command based on the voice uttered by the user. A command word is assigned to each command. For example, the command word "start" is assigned to a command to start playing a piece of music. Further, the command word "stop" is assigned to the command to stop playing a song. Additionally, the command word "Key Agete" is assigned to the command to raise the key of a song by a semitone. Additionally, the command word "keysagete" is assigned to the command to lower the key of a song by a semitone.

A command code is an identification code assigned to each command. For example, a command code "wwwwww" is assigned to a command to start playing a song. Further, a command code "xxxxxx" is assigned to a command to stop playing a song.

The command table 31 is data indicating the correspondence between command words and command codes in each command. Command table 31 is stored in storage unit 9.

For example, when a user speaks "start" into the microphone 5, the voice is converted into an analog signal by the microphone 5 and input to the sound processing section 13, and then converted into a digital signal by the sound processing section 13. and input to the control section 8. The control unit 8 performs voice recognition processing on the digital signal corresponding to the input voice of "start", and detects the command word "start" from this digital signal. Next, the control unit 8 refers to the command table 31, identifies the command code "wwwwww" that corresponds to the detected command word "start", and starts the command corresponding to the identified command code "wwwwww", that is, starts playing. Execute the command to. As a result, the karaoke device 1 starts playing the music.

Furthermore, the karaoke apparatus 1 has a function of switching the voice operation function on and off according to the user's operation input. That is, the karaoke device 1 has two modes related to the voice operation function: a voice operation off mode in which commands are not executed according to voice input command words, and a voice operation on mode in which commands are executed according to voice input command words. has been done. When the user uses the remote control device 3 to turn on the voice operation function, the control unit 8 selects the voice operation on mode. Further, when the user uses the remote control device 3 to turn off the voice operation function, the control unit 8 selects the voice operation off mode. Note that the voice operation off mode is a specific example of the "first mode," and the voice operation on mode is a specific example of the "second mode."

In addition, the karaoke device 1 is configured to detect a command word from the voice of the user who is performing karaoke singing when a song is being played and karaoke singing is performed with the voice operation on mode selected. It has a command execution restriction function that restricts the execution of commands corresponding to command words. This will be discussed in detail later.

In FIG. 1, the control unit 8 includes a mode selection unit 21, a command word detection unit 22, a storage control unit 23, an execution determination unit 24, and a command execution unit 25 as configurations for realizing the functions related to the voice operation described above. have. These configurations are realized by the microprocessor of the control unit 8 reading and executing a computer program stored in the storage unit 9, for example. Note that the mode selection section 21 is a specific example of a "selection section," the command word detection section 22 is a specific example of a "detection section," and the execution judgment section 24 is a specific example of a "judgment section."

The mode selection unit 21 has a function of selecting either the voice operation off mode or the voice operation on mode according to the user's operation input. That is, when the user uses the remote control device 3 to turn on the voice operation function, the mode selection unit 21 selects the voice operation on mode, and when the user uses the remote control device 3 to turn on the voice operation function. Select the voice operation off mode when you perform an operation to turn it off.

The command word detection unit 22 has a function of detecting a command word from input audio (including karaoke singing audio input during the performance of a song). That is, the command word detection unit 22 performs voice recognition processing on the voice input through the microphone 5 and converted into a digital signal by the audio processing unit 13, and detects a command word from this voice.

If the mode selection unit 21 selects the voice operation off mode when the command word detection unit 22 detects the command word, the storage control unit 23 detects the position of the detected command word in the song. It has a function of storing location information and the like in the storage unit 9 in association with the music identification information of the music. This will be discussed in detail later.

If the voice operation on mode is selected by the mode selection unit 21 when the command word detection unit 22 detects the command word, the execution determination unit 24 determines the position of the detected command word in the song and the memory. It has a function of determining whether or not to execute a command in accordance with the detected command word, based on detected position information and the like stored in association with the music identification information of the music by the control unit 23. This will be discussed in detail later.

The command execution section 25 has a function of executing a command according to the command word detected by the command word detection section 22. That is, when a command word is detected by the command word detection section 22, the command execution section 25 refers to the command table 31, specifies the command code corresponding to the detected command word, and executes a command corresponding to the specified command code. Execute the command to. Execution of commands by the command execution unit 25 may be restricted by a command execution restriction function. This point will be discussed later.

(Command execution restriction function)
As described above, when the voice operation on mode is selected and a command word is detected from the voice of karaoke singing, the karaoke device 1 sets a command execution restriction that restricts the execution of the command corresponding to the command word. It has a function. The command execution restriction function is realized by the following method.

(1) While music is being played and karaoke singing is being performed with the voice operation off mode selected, the command word detection unit 22 detects command words from the user's karaoke singing voice. During this time, when the command word detection unit 22 detects a command word from the karaoke singing voice, the storage control unit 23 stores detection position information indicating the position of the detected command word in the song and the detected command word. Detection number information indicating the number of times a command word has been detected at the position where the command word has been detected is stored in the storage unit 9 in association with the music identification information of the music.

Specifically, when a command word is detected from the karaoke singing voice by the command word detection unit 22 while a song is being played and karaoke singing is being performed with the voice operation off mode selected, the memory control is performed. The unit 23 adds the music identification information of the music being played, the detection position information, and the detection number information to the command word detection information group 32 stored in the storage unit 9. The command word detection information group 32 is, for example, as shown in FIG. 3(A), an information group in which music identification information, detection position information, and detection number information of a music piece are arranged in correspondence with each other. , are stored in the storage unit 9. The song identification information is, for example, a several-digit numerical value unique to each song. Further, the detected position information is, for example, information indicating the bar number of the music being played at the time the command word is detected. Further, the detection count information is information indicating the number of times a command word has been detected in a bar in which a command word has been detected.

For example, with the voice operation off mode selected, a song with song identification information "aaaaa" is played and karaoke singing is performed, and during this time, at the 16th measure of the song, a command word is heard for the first time from the karaoke singing voice. If detected, the storage control unit 23 associates the music identification information “aaaaa”, the detection position information “16”, and the detection number information “1” with each other, and detects the command word stored in the storage unit 9. Add to information group 32. After that, with the voice operation off mode selected, the song with the song identification information "aaaaa" is played and karaoke sings again, and during the 16th measure of the song, a command word is heard from the karaoke singing voice. If detected, the storage control unit 23 sets the detection number information corresponding to the detection position information “16” of the song identification information “aaaaa” to “1” in the command word detection information group 32 stored in the storage unit 9. ” to “2”. In the command word detection information group 32 shown in FIG. 3(A), the detection number information corresponding to the detection position information "16" of the song identification information "aaaaa" is "5". This means that the song with the song identification information "aaaaa" is played and karaoke-sung more than 5 times with the voice operation off mode selected, and during that time, a command is issued from the karaoke-singing voice at the 16th measure of the song. This means that the word was detected a total of 5 times.

(2) On the other hand, while music is being played and karaoke singing is being performed with the voice operation on mode selected, the command word detection unit 22 detects command words from the user's karaoke singing voice. During this period, when the command word detection unit 22 detects a command word from the karaoke singing voice, the execution determination unit 24 determines the position of the detected command word in the song, and the storage control unit 23 determines the song identification information of the song. Based on the detected position information and the like stored in association with the detected command word, it is determined whether or not to execute the command according to the detected command word.

The specific method for making this determination is as follows. That is, in the command word detection information group 32 stored in the storage unit 9, there is a piece of music that corresponds to the music identification information of the music that is currently being played and that is being played at the time when the command word is detected. When there is detection position information that matches the bar number and the number of detections indicated by the song identification information and the detection number information corresponding to the detection position information is greater than or equal to a predetermined judgment reference value, the execution judgment unit 24 , it is determined that the command corresponding to the command word is not to be executed. The above-mentioned judgment reference value is set to "1", for example. On the other hand, in the command word detection information group 32 stored in the storage unit 9, there is a piece of music that corresponds to the music identification information of the music currently being played and that is being played at the time when the command word is detected. When there is no detected position information that matches the bar number, or when there is no detected position information that matches the measure number, or when there is a command word that corresponds to the song identification information of the currently played song and is included in the command word detection information group 32 stored in the storage unit 9. There is detection position information that matches the measure number of the song being played at the time when the song is detected, but the number of detections indicated by the song identification information and the detection number information corresponding to the detection position information is less than the above criterion value. If so, the execution determining unit 24 determines to execute the command corresponding to the command word.

For example, assume that the command word detection information group 32 shown in FIG. 3(A) is stored in the storage unit 9. In this state, the voice operation on mode is selected, and the song with the song identification information "aaaaa" is played and karaoke singing is performed. During the 16th measure of the song, a command is issued from the user's karaoke singing voice. Suppose a word is detected. In this case, in the command word detection information group 32 shown in FIG. Since the number of detections "5" indicated by the number of detections information corresponding to the music identification information and the detection position information is greater than or equal to the above judgment reference value, the execution judgment unit 24 judges not to execute the command corresponding to the command word. do.

When the execution determination unit 24 determines that the command corresponding to the command word is not to be executed, the command execution unit 25 does not execute the command. On the other hand, if the execution determination unit 24 determines that the command corresponding to the command word is to be executed, the command execution unit 25 executes the command.

(Operation example 1)
FIG. 4 shows the operation of the karaoke apparatus 1 for realizing the command execution restriction function. Hereinafter, four operational examples of the karaoke apparatus 1 will be described using FIG. 4.

First, operation example 1 will be explained. Operation example 1 is an operation example in a case where the music with the music identification information "bbbbb" is played and karaoke singing is performed in a state where the voice operation off mode is selected. The lyrics of the 24th measure and the 48th measure of the song with the song identification information "bbbbbb" include "stop", which is the same word as the command word "stop". However, other than these, the lyrics of this song do not include the word "stop". Furthermore, at the start of the operation of operation example 1, the storage unit 9 stores a command word detection information group 32 shown in FIG. 3(A). Furthermore, the default setting of the mode of the voice operation function in the karaoke apparatus 1 is the voice operation off mode, and at the start of the operation of operation example 1, the voice operation off mode is maintained in a selected state.

User G entered a karaoke room where karaoke device 1 was installed. User G did not wish to use the voice operation function, and therefore did not perform an operation to switch the mode related to the voice operation function. In this case, the mode selection unit 21 in the karaoke apparatus 1 does not switch the mode regarding the voice operation function (step S1: NO).

Thereafter, the user G used the remote control device 3 to specify the song with the song identification information "bbbbb" and input an instruction to start playing this song. In this case, the control unit 8 of the karaoke device 1 stores the music identification information “bbbbb” specified by the user G in the storage unit 9, and then controls the music of the music identification information “bbbbb” stored in the storage unit 9. Based on the music data, the performance of the music is started (step S3).

User G picked up microphone 5 and started singing karaoke. While the music is being played and karaoke singing is being performed, the user G's voice input into the karaoke device main body 2 via the microphone 5 is converted into a digital signal by the audio processing unit 13 and input into the control unit 8. Ru. Then, the command word detection unit 22 performs voice recognition processing on the user G's voice converted into a digital signal, and monitors the appearance of a command word included in this voice. Further, while the music is being played, the control unit 8 counts the bar number of the music that is being played.

When the performance reached the 24th measure of the song, user G uttered "stop" as part of the lyrics of the song. In this case, the command word detection unit 22 detects the command word "stop" when the performance reaches the 24th measure of the music (step S4: YES).

Subsequently, the control unit 8 determines whether the voice operation off mode is selected as the mode related to the voice operation function (step S5). Since the mode related to the voice operation function has not been switched since the start of operation example 1, the voice operation off mode is currently selected (step S5: YES). In this case, the storage control unit 23 adds music identification information “bbbbb”, detection position information “24”, and detection number information “1” to the command word detection information group 32 stored in the storage unit 9, respectively. They are added in association (step S6). Note that when the voice operation off mode is selected, even if the command word detection section 22 detects a command word, the command execution section 25 does not execute the command corresponding to the command word. Subsequently, the control unit 8 determines whether or not the performance of the music has ended, and if the performance of the music has not ended (step S7: NO), the process returns to step S4.

Subsequently, when the performance reached the 48th bar of the song, User G again uttered "stop" as part of the lyrics of the song. In this case, the command word detection unit 22 detects the command word "stop" when the performance reaches the 48th measure of the music (step S4: YES). At this time, since the voice operation off mode is selected (step S5: YES), the storage control unit 23 adds the song identification information “bbbbb” to the command word detection information group 32 stored in the storage unit 9. Detection position information "48" and detection number information "1" are added in association with each other (step S6). Subsequently, the control unit 8 determines whether or not the performance of the music has ended, and if the performance of the music has not ended (step S7: NO), the process returns to step S4.

On the other hand, in step S7, when the control unit 8 determines whether or not the performance of the music has ended (step S7: YES), the control unit 8 returns the process to step S1.

By the operation of operation example 1, detection position information and detection number information corresponding to the song identification information "bbbbb" are added to the command word detection information group 32 stored in the storage unit 9. As a result, at the end of operation example 1, the command word detection information group 32 changes from the state shown in FIG. 3(A) to the state shown in FIG. 3(B).

(Operation example 2)
Next, operation example 2 will be explained. In operation example 2, after the operation in operation example 1 is performed, the mode related to the voice operation function is switched to voice operation on mode, and in that state, the song with the song identification information "bbbbb" is played and karaoke singing is performed. This is an example of how it works. At the start of the operation of operation example 2, the storage unit 9 stores a command word detection information group 32 shown in FIG. 3(B). Furthermore, at the start of the operation in operation example 2, the voice operation off mode is selected as the mode of the voice operation function.

User H, who is different from user G, enters a karaoke room where karaoke device 1 is installed. Using the remote control device 3, the user H performed an operation input to switch the mode related to the voice operation function from the voice operation off mode to the voice operation on mode. In this case, the mode selection unit 21 switches the mode regarding the voice operation function from the voice operation off mode to the voice operation on mode. That is, the mode selection unit 21 selects the voice operation on mode (step S1: YES, step S2).

Thereafter, the user H operated the remote control device 3 to specify the song with the song identification information "bbbbb" and input an instruction to start playing this song. In this case, the control unit 8 stores the music identification information “bbbbb” designated by the user H in the storage unit 9, and then stores the music data of the music with the music identification information “bbbbb” stored in the storage unit 9. Based on this, the performance of the music piece is started (step S3).

User H picked up microphone 5 and started singing karaoke. While the music is being played and karaoke singing is being performed, the command word detection unit 22 performs voice recognition processing on the user H's voice input through the microphone 5 and converted into a digital signal, Monitor the occurrence of command words contained within. Further, while the music is being played, the control unit 8 counts the bar number of the music that is being played.

When the performance reached the 24th measure of the song, user H uttered "stop" as part of the lyrics of the song. In this case, the command word detection unit 22 detects the command word "stop" when the performance reaches the 24th measure of the music (step S4: YES).

Subsequently, the control unit 8 determines whether the voice operation off mode is selected (step S5). In operation example 2, the mode selection unit 21 selects the voice operation on mode in step S2 (step S5: NO). In this case, the execution determination unit 24 determines whether or not the music identification information “bbbbb” of the music being played exists in the command word detection information group 32 stored in the storage unit 9 (step S8 ).

As shown in FIG. 3B, music identification information "bbbbb" is present in the command word detection information group 32 stored in the storage unit 9 (step S8: YES). In this case, the execution determination unit 24 subsequently selects the song being played at the time when the command word is detected in the detection position information corresponding to the song identification information "bbbbb" in the command word detection information group 32. It is determined whether detected position information matching bar number "24" exists (step S9).

As shown in FIG. 3(B), in the command word detection information group 32, among the detected position information corresponding to the song identification information "bbbbb", there is detected position information that matches the measure number "24". (Step S9: YES). In this case, the execution determining unit 24 subsequently determines whether or not the detection number information corresponding to the detected position information is equal to or greater than the determination reference value (step S10).

As shown in FIG. 3(B), in the command word detection information group 32, the detection indicated by the detection number information corresponding to the detection position information that corresponds to the music identification information "bbbbb" and matches the measure number "24" The number of times is "1", which is greater than or equal to the criterion value (for example, "1") (step S10: YES). In this case, the execution determining unit 24 determines not to execute the command corresponding to the command word "stop" detected by the command word detecting unit 22 (step S11). In this case, the command execution section 25 does not execute the command corresponding to the command word "stop" detected by the command word detection section 22. Therefore, the performance of the music continues. Subsequently, the control unit 8 determines whether or not the performance of the music has ended, and if the performance of the music has not ended (step S7: NO), the process returns to step S4.

Subsequently, when the performance reached, for example, the 30th measure of the song, user H stopped the karaoke singing and uttered "stop" to stop the performance of the song. In this case, the command word detection unit 22 detects the command word "stop" when the performance reaches the 30th measure of the music (step S4: YES).

At this time, since the voice operation on mode is selected, the execution determination unit 24 determines that the music identification information “bbbbb” of the music being played is included in the command word detection information group 32 stored in the storage unit 9. It is determined whether it exists (step S8).

As shown in FIG. 3B, since the music identification information "bbbbb" exists in the command word detection information group 32 stored in the storage unit 9 (step S8: YES), the execution determination unit 24 Next, in the command word detection information group 32, the detection position information corresponding to the music identification information "bbbbb" matches the measure number "30" of the music being played at the time the command word was detected. It is determined whether detected position information exists (step S9).

As shown in FIG. 3(B), in the command word detection information group 32, among the detected position information corresponding to the music identification information "bbbbb", there is no detected position information that matches the measure number "30". Therefore, the execution determining unit 24 determines to execute the command corresponding to the command word “stop” detected by the command word detecting unit 22 (step S12). In this case, the command execution section 25 executes the command corresponding to the command word "stop" detected by the command word detection section 22 (step S13). The control unit 8 immediately stops playing the music according to the executed command. Then, upon completion of the music performance (step S7: YES), the process returns to step S1.

To summarize the operations in operation example 1 and operation example 2, first, in operation example 1, while the voice operation off mode is selected and the song with song identification information "bbbbb" is being played and karaoke singing is being performed, When the command word detection unit 22 detects the command word "stop" from the karaoke singing voice, the song identification information, detection position information, and detection number information of the song are respectively associated with each other to generate a command word detection information group. 32 will be added. After that, in operation example 2, while the music with the music identification information "bbbbb" is being played and karaoke singing is being performed with the voice operation on mode selected, the command word detection unit 22 detects the karaoke singing voice. When the command word "stop" is detected, the command word "stop" is detected based on the command word detection information group 32 to which the song identification information, detection position information, and detection number information of the song are added in operation example 1. Whether the bar number of the song at the time when the music is detected matches the detected position information corresponding to the song identification number "bbbbb", and whether the number of detections indicated by the detection number information corresponding to the detected position information is equal to or greater than the above criteria. is judged. If this determination is affirmative, it is determined that the command corresponding to the command word "stop" is not to be executed, and the command is not executed. As a result, the moment a user utters "stop" as part of the lyrics while singing a song at karaoke, the command corresponding to the command word "stop" is executed, causing the song to start playing against the user's will. This prevents the performance from being stopped. On the other hand, if the above determination is negative, it is determined that the command corresponding to the command word "stop" is to be executed, and a command to stop playing the music is executed. As a result, when the user utters "stop" to stop the music while the music is being played, the music is stopped.

(Operation example 3)
Next, operation example 3 will be explained. Operation example 3 is an operation example when the music with the music identification information "ccccc" is played and karaoke singing is performed in a state where the voice operation off mode is selected. The lyrics of the 15th measure of the song with the song identification information "ccccc" include the word "stock" which is aurally similar to the command word "stop". Furthermore, at the start of the operation of operation example 3, the storage unit 9 stores a command word detection information group 32 shown in FIG. 3(B). Furthermore, at the start of the operation in operation example 3, the voice operation off mode is selected.

User G entered a karaoke room where karaoke device 1 was installed. User G did not perform any operation to switch the mode regarding the voice operation function. In this case, the mode selection unit 21 does not switch the mode regarding the voice operation function (step S1: NO).

Thereafter, the user G operated the remote control device 3 to specify the song with the song identification information "ccccc" and input an instruction to start playing this song. In this case, the control unit 8 stores the music identification information “ccccc” designated by the user G in the storage unit 9, and then stores the music data of the music with the music identification information “ccccc” stored in the storage unit 9. Based on this, the performance of the music piece is started (step S3).

User G picked up microphone 5 and started singing karaoke. Thereafter, when the performance reached the 15th measure of the song, User G uttered "Stock" as part of the lyrics of the song. At this time, the command word detection unit 22 erroneously detected "stock" as the command word "stop". In this case, since the control unit 8 does not recognize the erroneous detection of the command word by the command word detection unit 22, the control unit 8 repeats the process from step 4 to Move to S5.

Subsequently, in step S5, the control unit 8 determines whether the mode related to the voice operation function is the voice operation off mode. At this point, the mode related to the voice operation function is the voice operation off mode (step S5: YES), so the storage control unit 23 adds the song identification information " ccccc", detection position information "15", and detection number information "1" are added in association with each other (step S6).

Thereafter, the command word detection unit 22 did not detect a command word or erroneously detect a command word until the performance of the music was finished. In step S7, the control unit 8 determines whether or not the performance of the music has ended, and if the performance of the music has ended (step S7: YES), the process returns to step S1.

By the operation of operation example 3, detection position information and detection number information corresponding to the song identification information "ccccc" are added to the command word detection information group 32 stored in the storage unit 9. As a result, at the end of operation example 3, the command word detection information group 32 changes from the state shown in FIG. 3(B) to the state shown in FIG. 3(C).

(Operation example 4)
Next, operation example 4 will be explained. In operation example 4, after the operation in operation example 3 is performed, the mode related to the voice operation function is switched to voice operation on mode, and in that state, the song with the song identification information "ccccc" is played and karaoke singing is performed. This is an example of how it works. At the start of the operation of operation example 4, the storage unit 9 stores a command word detection information group 32 shown in FIG. 3(C). Furthermore, at the start of the operation in operation example 4, the voice operation off mode is selected as the mode of the voice operation function.

A user H entered a karaoke room in which a karaoke device 1 was installed. Using the remote control device 3, the user H performed an operation input to switch the mode related to the voice operation function from the voice operation off mode to the voice operation on mode. In this case, the mode selection unit 21 switches the mode regarding the voice operation function from the voice operation off mode to the voice operation on mode (step S1: YES, step S2).

Thereafter, the user H operated the remote control device 3 to specify the song with the song identification information "ccccc" and input an instruction to start playing this song. In this case, the control unit 8 stores the music identification information “ccccc” in the storage unit 9 and then controls the performance of the music based on the music data of the music with the music identification information “cccc” stored in the storage unit 9. Start (step S3).

User H picked up microphone 5 and started singing karaoke. Thereafter, when the performance reached the 15th measure of the song, User H uttered "Stock" as part of the lyrics of the song. At this time, the command word detection unit 22 erroneously detected "stock" as the command word "stop". Even in this case, since the control unit 8 does not recognize the erroneous detection of the command word by the command word detection unit 22, the process starts from step 4 in the same way as when the command word is correctly detected by the command word detection unit 22. The process moves to step S5.

Subsequently, in step S5, the control unit 8 determines whether the mode related to the voice operation function is the voice operation off mode. The mode related to the voice operation function is switched to voice operation on mode. (Step S5: NO). In this case, the execution determination unit 24 determines whether or not the music identification information “ccccc” of the music being played exists in the command word detection information group 32 stored in the storage unit 9 (step S8 ).

As shown in FIG. 3C, music identification information "ccccc" is present in the command word detection information group 32 stored in the storage unit 9 (step S8: YES). In this case, the execution determination unit 24 subsequently selects the song being played at the time when the command word is detected in the detection position information corresponding to the song identification information "ccccc" in the command word detection information group 32. It is determined whether detected position information matching bar number "15" exists (step S9).

As shown in FIG. 3(C), in the command word detection information group 32, among the detected position information corresponding to the song identification information "ccccc", there is detected position information that matches the bar number "15". (Step S9: YES). In this case, the execution determining unit 24 subsequently determines whether or not the detection number information corresponding to the detected position information is equal to or greater than the determination reference value (step S10).

As shown in FIG. 3(C), in the command word detection information group 32, the detection indicated by the detection number information corresponding to the detection position information that corresponds to the music identification information "cccc" and matches the measure number "15" The number of times is "1", which is greater than or equal to the criterion value (for example, "1") (step S10: YES). In this case, the execution determining unit 24 determines not to execute the command corresponding to the command word "stop" detected by the command word detecting unit 22 (step S11). In this case, the command execution section 25 does not execute the command corresponding to the command word "stop" detected by the command word detection section 22. Therefore, the performance of the music continues.

Thereafter, the command word detection unit 22 did not detect a command word or erroneously detect a command word until the performance of the music was finished. In step S7, the control unit 8 determines whether or not the performance of the music has ended, and if the performance of the music has ended (step S7: YES), the process returns to step S1.

To summarize the operations in operation example 3 and operation example 4, first, in operation example 3, while the voice operation off mode is selected and the song with song identification information "ccccc" is being played and karaoke singing is being performed, , when the command word detection unit 22 erroneously detects the word "stock" which is not a command word from the karaoke singing voice as the command word "stop", the song identification information, detection position information and detection number information of the song are respectively They are added to the command word detection information group 32 in correspondence with each other. After that, in operation example 4, while the music with the music identification information "ccccc" is being played and karaoke singing is being performed with the voice operation on mode selected, the command word detection unit 22 detects the sound of karaoke singing. Therefore, when the word "stock" which is not a command word is erroneously detected as the command word "stop", the command corresponding to the erroneously detected command word "stop" must be executed based on the command word detection information group 32. be judged. As a result, the moment a user utters the word "stock" as part of the lyrics while singing a song karaoke, the command word "stop" is erroneously detected, and the command corresponding to the command word "stop" is executed. It is possible to prevent the performance of a song from being stopped against the user's will.

As explained above, in the karaoke apparatus 1 according to the first embodiment of the present invention, if the voice operation off mode is selected when a command word is detected from the user's voice while playing music, the memory control The unit 23 stores the music identification information of the music being played, the detection position information indicating the bar number in the music of the detected command word, and the number of times the command word was detected at the position where the command word was detected. The detection number information shown is added to the command word detection information group 32 stored in the storage unit 9. On the other hand, if the voice operation on mode is selected when a command word is detected from the user's voice while playing a song, the execution determination unit 24 selects the command word detection information group stored in the storage unit 9. 32, there is detected position information that corresponds to the song identification information of the song being played and that matches the bar number of the song that is being played at the time the command word is detected, and the song identification information It is determined whether or not the condition that the number of detections indicated by the information and the number of detections information corresponding to the detected position information is equal to or greater than a predetermined judgment reference value is met, and if such a condition is met, the number of detections is not detected. It is determined that the command corresponding to the specified command word will not be executed. With this configuration, as explained in operation examples 3 and 4, even if a command word is erroneously detected during karaoke singing, execution of the command corresponding to the command word can be suppressed. In other words, even though the user has no intention of using the voice operation function and the voice operation off mode is selected based on the user's operation, the command word is detected while the song is being played. The presence of a word the same as a command word or a word similar to a command word in lyrics (more precisely, the position and number of times a command word is detected or erroneously detected in a song) is recognized. Therefore, when a command word is detected or erroneously detected while a song is being played with voice operation on mode selected, the command corresponding to the detected or erroneously detected command word is executed. Whether or not the voice operation off mode is selected can be determined based on the result of the above recognition performed when the voice operation off mode is selected.

[Second embodiment]
FIG. 5 shows the configuration of a karaoke apparatus 51 according to a second embodiment of the present invention. In FIG. 5, a karaoke apparatus 51 differs from the karaoke apparatus 1 of the first embodiment in that a control section 53 in a karaoke apparatus main body 52 includes a storage control section 54, an execution determination section 55, and a reservation section 56. The configuration of the karaoke device 51 other than these is the same as the karaoke device 1 of the first embodiment. In the karaoke apparatus 51 shown in FIG. 5, the same components as the karaoke apparatus 1 of the first embodiment shown in FIG.

In the karaoke device 51 of the second embodiment, the storage control unit 54 causes the command word detection unit 22 to control the karaoke singing while the music is being played and the karaoke singing is being performed with the voice operation off mode selected. When a command word is detected from audio, detection position information indicating the position (measure number) of the detected command word in the song and detection indicating the number of times the command word was detected at the position where the command word was detected. The number information is stored in the storage unit 9 in association with the music identification information of the music and the user identification information of the user.

Specifically, the memory control unit 54 causes the command word detection unit 22 to detect a command word from the voice of karaoke singing while the music is being played and karaoke singing is being performed with the voice operation off mode selected. When the command word detection information stored in the storage unit 9 is generated, the song identification information of the song being played, the usage identification information of the singing user, the detection position information, and the detection number information are stored in the storage unit 9. Add to group 58.

FIG. 6 shows an example of the command word detection information group 58 in the second embodiment. As shown in FIG. 6, in the command word detection information group 58 in the second embodiment, song identification information of a song, user identification information of a user, detected position information, and detection number information are associated with each other. They are arranged in the same way.

In addition, in the karaoke device 51 of the second embodiment, the execution determination unit 55 causes the command word detection unit 22 to perform karaoke while the music is being played and karaoke singing is performed with the voice operation on mode selected. When a command word is detected from the singing voice, the position (measure number) of the detected command word in the song, and the storage control unit 54 associates it with the song identification information of the song and the user identification information of the user. Based on the stored detected position information, etc., it is determined whether or not to execute a command according to the detected command word.

The specific method for making this determination is as follows. That is, in the command word detection information group 58 stored in the storage unit 9, there is a message that corresponds to the music identification information of the music being played, corresponds to the user identification information of the user who is singing, and There is detection position information that matches the bar number of the song being played at the time the command word is detected, and the song identification information, the user identification information, and the detection number information corresponding to the detection position information are When the indicated number of detections is equal to or greater than a predetermined determination reference value, the execution determining unit 55 determines not to execute the command corresponding to the command word. On the other hand, in the command word detection information group 58 stored in the storage unit 9, there is a command word that corresponds to the music identification information of the music being played, corresponds to the user identification information of the user who is singing, and When there is no detection position information that matches the measure number of the song being played at the time the command word is detected, or when the command word is being played in the command word detection information group 58 stored in the storage unit 9. There is detected position information that corresponds to the song identification information of the song, corresponds to the user identification information of the user who is singing, and matches the bar number of the song being played at the time the command word is detected. However, when the number of detections indicated by the number of detections information corresponding to the song identification information, the user identification information, and the detection position information is less than the above-mentioned criterion value, the execution judgment unit 55 determines that the number of detections corresponding to the command word is Decide to execute the command.

Furthermore, in the karaoke apparatus 51 of the second embodiment, the reservation section 56 has a function of making a reservation for the performance of a song by a user. The reservation section 56 is realized by the microprocessor of the control section 8 reading and executing a computer program stored in the storage section 9 of the karaoke apparatus main body 52, for example. When the user performs an operation input to reserve a piece of music, the reservation unit 56 associates the song identification information of the song and the user identification information of the user with each other and stores them in the storage unit 9 according to the user's operation input. (register. Specifically, the karaoke device 51 acquires the user identification information of the user through a login operation performed by the user when starting use. Furthermore, when the user makes a music reservation, the reservation unit 56 selectably displays the user identification information of the user acquired at the start of use on the touch panel display 4 of the remote control device 3, so that the user can When the device 3 is operated to designate a song and select its own user identification information, the music identification information of the specified song and the selected user identification information are associated with each other and stored in the storage unit 9. to be memorized. Note that the user identification information is, for example, a several-digit numerical value unique to each user.

FIG. 7 shows the operation of the karaoke apparatus 51 for realizing the command execution restriction function. The operation of the karaoke device 51 will be explained using FIG. 7. In FIG. 7, when the user uses the remote control device 3 to perform an operation input to switch the mode related to the voice operation function (step S21: YES), the mode selection unit 21 in the karaoke device 51 changes the mode related to the voice operation function. The mode is switched (step S22).

Further, when the user uses the remote control device 3 to input the song identification information of the song he or she wants to sing and reserves the performance of the song (step S23), the reservation unit 56 stores the song identification information input by the user. and the user identification information acquired by the user's login operation are stored (registered) in the storage unit 9 in association with each other (step S24).

Subsequently, the control unit 53 starts playing the reserved music (step S25). In response to this, the user picks up the microphone 5 and starts singing karaoke. While the music is being played and karaoke singing is being performed, the command word detection unit 22 performs voice recognition processing on the user's voice input through the microphone 5 and converted into a digital signal, Watch for occurrences of command words contained in . Further, while the music is being played, the control unit 53 counts the bar number of the music that is being played.

When the command word detection unit 22 detects a command word from the user's voice input through the microphone 5 and converted into a digital signal (step S26: YES), the control unit 53 then turns the voice operation off. It is determined whether the mode is selected (step S27). If the voice operation off mode is selected (step S27: YES), the storage control unit 54 adds the music of the song being played to the command word detection information group 58 stored in the storage unit 9. identification information, user identification information of the user who is singing, detection position information indicating the bar number of the song being played at the time the command word was detected, and the bar in which the command word was detected. Detection number information indicating the number of times the command word has been detected is added in association with each other (step S28). Next, the control unit 53 determines whether or not the performance of the music has ended (step S29), and if the performance of the music has not ended, the process returns to step S26, and if the performance of the music has ended, the control unit 53 determines whether or not the performance of the music has ended. Then, the process returns to step S21.

On the other hand, when the command word detection unit 22 detects a command word from the user's voice input through the microphone 5 and converted into a digital signal, if the voice operation on mode is selected (step S26 : YES, step S27: NO), the execution determination unit 55 determines whether or not the music identification information of the music being played exists in the command word detection information group 58 stored in the storage unit 9. (Step S30).

If the command word detection information group 58 includes music identification information of the music being played (step S30: YES), then the execution determination unit 55 determines whether the music to be played is included in the command word detection information group 58 (step S30: YES), It is determined whether the user identification information of the user who is singing exists in the user identification information corresponding to the music identification information of the song being played (step S31).

In the command word detection information group 58, if the user identification information of the user who is singing exists among the user identification information corresponding to the music identification information of the music being played (step S31: YES), the execution determination unit 55 then detects, in the command word detection information group 58, detection position information that corresponds to both the song identification information of the song being played and the user identification information of the user who is singing. It is determined whether there is detected position information that matches the bar number of the song being played at the time the command word is detected (step S32).

In the command word detection information group 58, at the time when a command word is detected in the detection position information corresponding to both the song identification information of the song being played and the user identification information of the user who is singing, If there is detected position information that matches the measure number of the song being played (step S32: YES), then the execution determining unit 24 determines that the detection number information corresponding to the detected position information meets the above criteria. It is determined whether or not the value is greater than or equal to the value (step S33).

If the detection number information corresponding to the detected position information is equal to or greater than the above-mentioned judgment reference value (step S33: YES), the execution judgment unit 24 executes the command corresponding to the command word detected by the command word detection unit 22. It is determined not to execute (step S34). In this case, the command execution section 25 does not execute the command corresponding to the command word detected by the command word detection section 22. Next, the control unit 53 determines whether or not the performance of the music has ended (step S29), and if the performance of the music has not ended, the process returns to step S26, and if the performance of the music has ended, the control unit 53 determines whether or not the performance of the music has ended. Then, the process returns to step S21.

On the other hand, in the command word detection information group 58, a command word is detected in the detection position information corresponding to both the song identification information of the song being played and the user identification information of the user who is singing. If there is no detected position information that matches the bar number of the song being played at the time (step S30: NO, step S31: NO, or step S32: NO), or if there is no detected position information that matches the measure number of the song being played at the time (step S30: NO, step S31: NO, or step S32: NO), The detection position information corresponding to both the song identification information of the song being played and the user identification information of the user singing the song matches the bar number of the song being played at the time the command word is detected. If there is detected position information that corresponds to the detected position information, but the detection number information corresponding to the detected position information is less than the above judgment reference value (step S33: NO), the execution judgment unit 55 causes the command word detection unit 22 to detect the detected position information. It is determined that the command corresponding to the given command word is to be executed (step S35). In this case, the command execution section 25 executes the command corresponding to the command word detected by the command word detection section 22 (step S36). Next, the control unit 53 determines whether or not the performance of the music has ended (step S29), and if the performance of the music has not ended, the process returns to step S26, and if the performance of the music has ended, the control unit 53 determines whether or not the performance of the music has ended. Then, the process returns to step S21.

As explained above, in the karaoke apparatus 51 of the second embodiment of the present invention, if the voice operation off mode is selected when a command word is detected from the user's voice while playing a song, the memory The control unit 54 associates the detection position information and detection number information of the detected command word with the music identification information of the music being played and the user identification information of the user who is singing, and generates command word detection information. Add to group 58. Further, if the voice operation on mode is selected when a command word is detected from the user's voice while playing a song, the execution determination unit 55 selects the command word detection information group stored in the storage unit 9. 32, the bar number of the song that corresponds to both the song identification information of the song being played and the user identification information of the user who is singing, and that is being played at the time the command word is detected. , and the number of detections indicated by the song identification information, the user identification information, and the detection number information corresponding to the detected location information is greater than or equal to a predetermined criterion value. If such a condition is satisfied, it is determined that the command corresponding to the detected command word is not to be executed. Therefore, according to the karaoke device 51 of the second embodiment, like the karaoke device 1 of the first embodiment, even if a command word is erroneously detected during karaoke singing, the command corresponding to the command word is Execution can be suppressed.

Furthermore, in the karaoke device 51 of the second embodiment, when the voice operation off mode is selected, a plurality of users sing the same song at karaoke, and the command word detection unit 22 detects or erroneously detects a command word. When detected, the detected position information and detection count information are added to the command word detection information group 58 in association with not only the song identification information of the song but also the user identification information of each user. That is, practically speaking, detection position information and detection number information regarding the same song are stored in the storage unit 9 for each user. After that, when a certain user sings the song at karaoke with the voice operation on mode selected, and the command word detection unit 22 detects or erroneously detects a command word, only the song identification information of the song is used. Whether or not to execute the command corresponding to the detected or erroneously detected command word is determined based on the presence of detected position information corresponding to the usage identification information of the user who is singing karaoke. . That is, practically speaking, it is determined for each user whether or not to execute a command corresponding to a command word detected from the karaoke singing voice of the song. The audio of karaoke singing differs depending on the voice quality or singing style of each individual user, so if multiple users perform karaoke singing of the same song, the audio of those karaoke singing will differ. Command words that are erroneously detected may vary depending on the user. Even in such a case, according to the karaoke device 51 of the second embodiment, when the voice operation off mode is selected, the detection position information and detection number information for the same song are stored for each user. , and when the song is karaoke-sung with the voice operation on mode selected, it is determined whether or not to execute a command corresponding to a command word detected or erroneously detected from the karaoke-singing audio. Since this is performed for each user, it is possible to accurately determine whether or not to execute a command corresponding to a command word while the music is being played.

[Third embodiment]
FIG. 8 shows the configuration of a karaoke apparatus 61 according to a third embodiment of the present invention. As shown in FIG. 8, in the karaoke apparatus 61, the control section 63 of the karaoke apparatus main body 62 has an output section 64. The configuration of the karaoke device 61 is the same as the configuration of the karaoke device 51 of the second embodiment except for this point. In FIG. 8, the same components as the karaoke device 51 shown in FIG. 5 are given the same reference numerals, and the explanation thereof will be omitted or simplified.

The output unit 64 stores detected position information associated with the song identification information of the song and the user identification information of the user in the storage unit 9 when the voice operation on mode is selected by the mode selection unit 21. If the detected position information associated with the song identification information of the song and the user identification information of the user is stored in the storage unit 9, a message based on the detected position information is sent. It has a function to output to the user.

Specifically, when the voice operation on mode is selected, the output unit 64 outputs the detected position information associated with the song identification information of the song and the user identification information of the user to the command word detection information group 58. If the detected position information exists in the command word detection information group 58, the same word as the command word is added to the lyrics of the song before the song starts playing. Alternatively, a message is displayed on the touch panel display 4 of the remote control device 3 to inform the user that the command will not be executed during karaoke singing even if a word that is confusing as a command word is included. Here, the same word as the command word is, for example, "stop" in Operation Example 1 and Operation Example 2 of the first embodiment. Further, the word that is confusing as a command word is, for example, "stock" in Operation Example 3 and Operation Example 4 of the first embodiment.

FIG. 9 shows the operation of the karaoke apparatus 61 for realizing the command execution restriction function. In FIG. 9, regarding the operations of the karaoke apparatus 61, the same operations as those of the karaoke apparatus 51 of the second embodiment shown in FIG. 7 are given the same reference numerals, and the explanation thereof will be omitted or simplified. In the operation of the karaoke apparatus 61 shown in FIG. 9, steps S41 to S43 are added between steps S24 and S25 in the operation of the karaoke apparatus 51 shown in FIG.

In FIG. 9, when the user performs an operation input to switch the mode related to the voice operation function, the mode selection unit 21 switches the mode related to the voice operation function (steps S21, S22). Further, when the user inputs the song identification information of the song he/she wants to sing and reserves the performance of the song, the reservation unit 56 stores the song identification information of the song and the user's user identification information in association with each other. 9 (steps S23, S24).

Subsequently, the output unit 64 determines whether the voice operation on mode is selected as the mode related to the voice operation function (step S41).

If the voice operation on mode is selected (step S41: YES), then the output unit 64 stores the detected position information corresponding to the song identification information and user identification information input by the user. It is determined whether the command word exists in the command word detection information group 58 stored in the unit 9 (step S42).

If detected position information corresponding to the music identification information and user identification information input by the user exists in the command word detection information group 58 (step S42: YES), the output unit 64 outputs the detected position information. A message based on the information is output to the user (step S43). Specifically, the output unit 64 reads detected position information corresponding to the music identification information and user identification information input by the user from the command word detection information group 58, and reads out the measure number indicated by the detected position information, and A message is displayed on the touch panel display 4 of the remote control device 3 to inform the user that the command will not be executed even if the lyrics of the song include the same word as the command word or a word confusingly similar to the command word. For example, the storage unit 9 stores the command word detection information group 58 shown in FIG. When the two pieces of detected position information read from the word detection information group 58 indicate measure numbers “24” and “48,” respectively, the output unit 64 outputs “the 24th measure and the 48th measure of the song with the song identification number bbbbb”. The lyrics of the song contain words that are the same as command words or are confusingly similar to command words, but no command will be executed based on these words while singing.'' is displayed on the touch panel display 4 of the remote control device 3. do.

On the other hand, if the voice operation off mode is selected (step S41: NO), or the detected position information corresponding to the song identification information and user identification information input by the user exists in the command word detection information group 58.
