Here, it is assumed that while one user is singing karaoke, another user searches for music by voice input using a remote control device. In this case, the remote control device may extract the search word from the singing voice accompanying the karaoke singing of one user instead of the voice of another user. As a result, the remote controller erroneously recognizes the search word, and there is a possibility that the search result different from the user's wish is presented.

On the other hand, there is a possibility that the lyrics of the music in which the user sings karaoke matches the command executed by voice input. For example, suppose a user utters the word "cancel", which is the lyrics of a song. In this case, the remote controller may mistakenly recognize the lyrics "stop" as the command "stop karaoke performance" and stop the karaoke performance.

An object of the present invention is to provide a karaoke input device capable of reducing erroneous recognition when using voice input in a karaoke singing place.

[Memory means]
The storage means 50a is a large-capacity storage device that stores various types of data, such as a hard disk drive. In the present embodiment, a part of the area of the storage means 50a functions as a data storage unit 100.

(Data storage)
The data storage unit 100 stores a plurality of commands and trigger words in association with different text data.

The command is a command corresponding to a process that can be executed when singing karaoke. The commands are, for example, "Increase the tempo of the karaoke performance", "Decrease the key of the karaoke performance", "Pause the karaoke performance", "Increase the volume of the microphone", "Decrease the volume from the speaker", " It is an instruction to execute a process such as "turn off the display of lyrics".

A trigger word is a word or short sentence for instructing the execution of a command or the search for a song. The trigger word is preferably a coined word that does not appear in the lyrics of the music or the conversation between users. As the trigger word, one word is set in advance for each remote controller.

Text data is data for identifying a command or trigger word. A different text data is associated with each of a plurality of commands and trigger words.

FIG. 3 is an example of a table stored in the data storage unit 100. For example, the text data of "tempo agete" is associated with the command C01 (which raises the tempo of the karaoke performance by 5%). Also, in this example, the text data "Karaoka" is associated as a trigger word. Text data that is not stored in the table is treated as if there is no corresponding command. Hereinafter, it is assumed that the table of FIG. 3 is stored in the data storage unit 100.

[Communication means / Display means / Input means / Sound collecting means]
The communication means 50b provides an interface for communicating with the karaoke body 10. The display means 50c is configured to display various types of information.

Alternatively, when the display means 50c is configured in the touch panel format, the display means 50c also functions as the input means 50d. The sound collecting means 50e is a microphone for collecting sound emitted by the user and outputting it as a voice signal.

[Control means]
The control means 50f performs various controls on the remote controller 50. The control means 50f includes a CPU and a memory (neither of which is shown). The CPU realizes various functions by executing a program stored in the memory.

Here, it is assumed that the user who uses the karaoke device K wants to input a command or a search word by voice. In this case, the user selects the "voice input" icon displayed on the display means 50c, for example, via the input means 50d. Based on the selection, the CPU of the control means 50f executes a program stored in the memory and shifts to the voice input mode. In this case, the control means 50f functions as a voice processing unit 200, a search unit 300, a notification unit 400, an execution unit 500, and a control unit 600.

(Voice processing unit)
The voice processing unit 200 performs voice recognition processing on the user's voice signal output from the sound collecting means 50e and outputs it as text data. A known method can be used for the voice recognition process.

For example, suppose that the user U utters "Kara OK" to the sound collecting means 50e. The sound collecting means 50e collects sound and outputs it as a voice signal to the voice processing unit 200. The voice processing unit 200 processes the voice signal and outputs the "color okay" indicated by the voice signal as text data.

(Search department)
The search unit 300 searches for music based on the search word. The search word is used when searching for a song for karaoke singing. Specifically, the search word is a singer name, a song name, a part of lyrics, or the like. The search unit 300 extracts a song including a search word from a plurality of songs. A known method can be used to search for music based on the search word. In the present embodiment, the search word is input by voice. The search unit 300 searches for music in response to an instruction from the control unit 600 (details will be described later).

(Notification unit)
The notification unit 400 notifies the user of the search result. For example, suppose that the search unit 300 extracts songs X1, X2, and X3 as search results. In this case, the notification unit 400 notifies the search result by displaying the music titles and music IDs of the music X1, the music X2, and the music X3 on the display means 50c. The search result may be notified by voice via a speaker (not shown) provided in the remote controller device 50.

(Execution department)
The execution unit 500 executes a command. The execution unit 500 executes a command stored in the storage means 50a based on an instruction from the control unit 600 (details will be described later).

(Control unit)
The control unit 600 acquires a trigger word based on the text data output by the voice processing unit 200.

For example, it is assumed that the text data "Kara OK" is output from the voice processing unit 200. The control unit 600 confirms whether or not the data corresponding to the output text data is stored in the data storage unit 100. According to the example of FIG. 3, the text data “Karaoka” is associated with the trigger word. In this case, the control unit 600 acquires the trigger word.

For example, it is assumed that the text data "Harahetta" is output from the voice processing unit 200. The control unit 600 confirms whether or not the data corresponding to the output text data is stored in the data storage unit 100. According to the example of FIG. 3, there is no trigger word or command associated with the text data “Harahetta”. In this case, the control unit 600 does not perform the following processing.

Here, the control unit 600 according to the present embodiment performs the first process and the second process. Hereinafter, each process will be described in detail.

In the first process, when the voice processing unit 200 outputs text data in which the voice processing unit 200 outputs text data after the trigger word is acquired and before the first predetermined time elapses, the search for a song using the text data as the search word is searched. This is a process instructing the unit 300. A value of 1 is set in advance for the first predetermined time, for example, "3 seconds".

Specifically, the control unit 600 starts timing when the trigger word is acquired. The control unit 600 confirms whether or not the voice processing unit 200 outputs text data by the time when the first predetermined time elapses after the trigger word is acquired. Here, it is assumed that the user U utters "Iruma chair" by the time when the first predetermined time elapses, and the text data "Ilmais" is output from the voice processing unit 200 based on the utterance. In this case, the control unit 600 determines the text data "Ilmais" as a search word. The control unit 600 instructs the search unit 300 to search for a song using "Ilmice" as a search word. The search unit 300 searches for music using the search word "Ilmais" based on the instruction.

On the other hand, if the voice processing unit 200 does not output the text data by the time when the first predetermined time elapses, the control unit 600 does not instruct the search unit 300 to search for the music.

If the text data is output before the first predetermined time elapses, or if the text data is not output until the first predetermined time elapses, the control unit 600 ends the time counting and the timer. To reset.

In the second process, when the text data associated with the command is output, the command associated with the text data is stored in the storage means 50a, the trigger word is acquired, and the command is stored in the storage means 50a. If so, after instructing the execution unit 500 to execute the memorized command, the memorized command is deleted, and when the second predetermined time elapses from the memorization of the latest command, the memorized command is memorized. This is the process to delete the existing command. A value of 1 is set in advance for the second predetermined time, for example, "3 seconds". The first predetermined time and the second predetermined time may be the same time or may be different.

For example, suppose that the user U who listens to the prelude part of the music X1 feels that the key is high and the tempo is fast for himself to sing the music X1 in karaoke. In this case, the user U utters "key down" and "tempo down" in order to the sound collecting means 50e. The voice processing unit 200 performs voice recognition processing on a voice signal based on the voice, and outputs "key sagete" and "tempo sagete" as text data.

The control unit 600 confirms whether or not the data corresponding to the output text data is stored in the data storage unit 100. According to the example of FIG. 3, the text data "key sagete" is associated with the command C05 (lower the key of the karaoke performance by one semitone), and the text data "tempo sagete" lowers the tempo of the karaoke performance by 5%. ) Is linked. Therefore, the control unit 600 stores the commands C05 and C02 associated with the text data "key sagete" and "tempo sagete" in the storage means 50a in the order in which they are uttered.

When the command is stored, the control unit 600 resets the timer and starts timing. When a plurality of commands are stored as in the above example, the control unit 600 resets the timer each time the commands are stored and starts new time counting.

It is assumed that the user U utters "Kara OK" and the control unit 600 acquires the trigger word. In this case, the control unit 600 instructs the execution unit 500 to execute the commands C05 and C02 stored in the storage means 50a. After giving the instruction, the control unit 600 deletes the stored command C05 and command C02 from the storage means 50a. When the command is deleted, the control unit 600 ends the timing.

On the other hand, when the second predetermined time elapses after the command C02 is stored, the control unit 600 deletes the command C05 and the command C02 from the storage means 50a. When the command is deleted, the control unit 600 ends the timing. That is, when the second predetermined time has elapsed from the storage of the latest command, the control unit 600 deletes the stored command.

Here, when a plurality of commands are stored, the control unit 600 can instruct the execution unit 500 to execute all the commands.

For example, the control unit 600 can instruct the execution unit 500 to execute all the commands in the memorized order. In the above example, when the trigger word is acquired and the command C05 and the command C02 are stored, the control unit 600 instructs the execution unit 500 to execute the command C05 and the command C02 in this order. Further, after giving the instruction, the control unit 600 deletes all the stored commands from the storage means 50a.

Based on the instruction, the execution unit 500 first executes a process of lowering the key of the karaoke performance of the music X1 by one semitone, and then executes a process of lowering the tempo by 5%.

Alternatively, when a plurality of commands are stored, the control unit 600 may instruct the execution unit 500 to execute only some of the commands.

For example, the control unit 600 may instruct the execution unit 500 to execute only the latest command, and then delete all the stored commands.

In the case of the above example, the storage means 50a stores the command C05 and the command C02 in this order. Here, when the trigger word is acquired, the control unit 600 instructs the execution unit 500 to execute only the latest command C02. Even when instructing the execution of some of the commands stored in this way, the control unit 600 deletes all the stored commands from the storage means 50a after the instruction.

The execution unit 500 executes only the process of lowering the tempo of the karaoke performance of the music X1 by 5% based on the instruction.

== Processing in the remote control device ==
Next, the process in the control unit 600 of the remote controller 50 according to the present embodiment will be described with reference to FIGS. 4A and 4B. FIG. 4A is a flowchart showing a process (first process) in the control unit 600 when searching for a song based on voice input. FIG. 4B is a flowchart showing a process (second process) in the control unit 600 when executing a command based on voice input. In this example, it is assumed that the voice input mode is being executed. Further, it is assumed that the data storage unit 100 stores a plurality of commands and one trigger word in association with different text data.

(First process)
The voice processing unit 200 performs voice recognition processing on the user's voice signal output from the sound collecting means 50e and outputs it as text data (text data output. Step 10).

The control unit 600 acquires a trigger word based on the text data output by the voice processing unit 200. Further, the control unit 600 starts timing when the trigger word is acquired (acquisition of the trigger word and start of timing. Step 11).

When the voice processing unit 200 outputs some text data (in the case of Y in step 12) from the acquisition of the trigger word to the elapse of the first predetermined time, the control unit 600 uses the certain text data as the search word. Instruct the search unit 300 to search for the music to be performed. Further, the control unit 600 ends the time measurement and resets the timer (search instruction and end of the time measurement. Step 13).

The search unit 300 searches for a song based on the instruction in step 13 (search for a song. Step 14).

The notification unit 400 notifies the user of the search result obtained in step 14 (notification of search result, step 15).

On the other hand, if the voice processing unit 200 does not output the text data (in the case of N in step 12) by the time when the first predetermined time elapses after acquiring the trigger word, the control unit 600 ends the time measurement. Then, the timer is reset, and the subsequent processing is not performed (timekeeping ends. Step 16).

(Second process)
The voice processing unit 200 performs voice recognition processing on the user's voice signal output from the sound collecting means 50e and outputs it as text data (text data output, step 20).

When the text data associated with the command is output, the control unit 600 stores the command associated with the text data in the storage means 50a. Further, when the command is stored, the control unit 600 resets the timer and starts timing (command storage, timer reset, and timing start. Step 21).

When the trigger word is acquired and the command is stored (Y in step 22), the control unit 600 instructs the execution unit 500 to execute the stored command (instructs the execution of the command. Step 23). ). The execution unit 500 executes a command based on the instruction in step 23.

After that, the control unit 600 deletes the stored command. Further, the control unit 600 ends the time measurement (command deletion and time measurement end. Step 24). On the other hand, when the second predetermined time has elapsed since the start of the timekeeping (in the case of Y in step 25), the control unit 600 deletes the stored command and ends the timekeeping (delete of the command and timekeeping). End of step 24).

As is clear from the above, the remote control device 50 according to the present embodiment is used when performing karaoke singing. The remote control device 50 is a data storage unit that stores a plurality of commands corresponding to processes that can be executed when singing karaoke, and trigger words for instructing execution of commands or search for songs in association with different text data. The 100, the voice processing unit 200 that performs voice recognition processing of the user's voice signal output from the sound collecting means 50e and outputs it as text data, the search unit 300 that searches for music based on the search word, and the user. On the other hand, the notification unit 400 that notifies the search result, the execution unit 500 that executes the command, and the control unit 600 that acquires the trigger word based on the text data output by the voice processing unit 200. When the voice processing unit 200 outputs some text data by the time when the first predetermined time elapses after the acquisition, the first processing of instructing the search unit 300 to search for a song using the certain text data as a search word. , And when the text data associated with the command is output, the command associated with the text data is stored in the storage means 50a, the trigger word is acquired, and the command is stored in the storage means 50a. , After instructing the execution unit 500 to execute the stored command, the stored command is deleted. On the other hand, when the second predetermined time has elapsed from the storage of the latest command, the stored command is deleted. It has a control unit 600 that performs a second process.

According to such a remote controller device 50, it is possible to search for a musical piece by voice input when the trigger word is acquired. Therefore, the possibility of erroneously recognizing the search word is reduced. Further, according to such a remote controller device 50, when the command is input by voice, the command is executed with the acquisition of the trigger word as a trigger. Therefore, there is a low possibility that an unintended command will be executed due to a misrecognition of the command. That is, according to the remote control device according to the present embodiment, it is possible to reduce erroneous recognition when using voice input in a karaoke singing place.

When the control unit 600 stores a plurality of commands, the control unit 600 instructs the execution unit 500 to execute all the commands in the stored order, and then deletes all the stored commands. With such a configuration, all commands can be executed in the order desired by the user. In addition, after instructing the execution of the command, all the memorized commands are deleted, so that the next voice input becomes possible.

On the other hand, when the control unit 600 stores a plurality of commands, the control unit 600 may instruct the execution unit 500 to execute only the latest command, and then delete all the stored commands. With such a configuration, only a part of the command desired by the user can be executed. In addition, after instructing the execution of the command, all the memorized commands are deleted, so that the next voice input becomes possible.

<Others>
The above embodiment has been described by taking the remote controller device 50 as an example of the input device for karaoke. On the other hand, the karaoke device K itself may function as a remote control device for karaoke. In this case, the karaoke body 10 has at least a storage means 50a (data storage unit 100), a communication means 50b, an input means 50d, and a control means 50f (voice processing unit 200, search unit 300, notification unit 400, execution unit 500, control unit 600). ) Is provided. Further, the display device 30 functions as the display means 50c, the remote control device 50 functions as the input means 50d, and the microphone 40 functions as the sound collecting means 50e.

In the example of the above embodiment, the priority may be set for a plurality of commands stored in the data storage unit 100. In this case, the data storage unit 100 stores priority information indicating the priority when executing a plurality of commands for each command. When the control unit 600 stores a plurality of commands, the control unit 600 instructs the execution unit 500 to execute the command based on the priority information, and then deletes all the stored commands. For example, in the example of the embodiment, it is assumed that the priority of the command C05 stored in the storage means 50a is set to "high" and the priority of the command C02 is set to "medium". In this case, the control unit 600 can instruct the execution unit 500 to execute only the high-priority command C05, or to execute the high-priority command C05 first.

In addition, depending on the user, it may be desired to cancel the command once input by voice. Therefore, the data storage unit 100 may store the cancel word for canceling the command input in association with the text data. In this case, the control unit 600 can acquire the cancel word based on the text data output by the voice processing unit 200. Further, when the cancel word is acquired, the control unit 600 deletes all the stored commands without instructing the execution unit 500 to execute the stored command.

For example, in the example of the embodiment, it is assumed that the command C05 and the command C02 are stored in the storage means 50a. Also, assume that the text data "Motoi" is associated with the cancel word.

The user utters the cancel word "Motoi" in order to cancel the command input by voice. The voice processing unit 200 outputs the text data "motoi". The control unit 600 confirms whether or not the data corresponding to the output text data is stored in the data storage unit 100. As mentioned above, the text data "Motoi" is associated with the cancellation word. Therefore, the control unit 600 acquires the cancel word. The control unit 600 deletes the command C05 and the command C02 stored in the storage means 50a from the storage means 50a without instructing the execution unit 500 to execute the command C05 and the command C02.

Further, the first process and the second process in the above embodiment may be continuously performed. That is, when the control unit 600 instructs the execution unit 500 to execute the command stored in the storage means 50a, and then the voice processing unit 200 outputs the text data before the first predetermined time elapses. , The search unit 300 may be instructed to search for music using the text data as a search word.

On the contrary, after instructing the execution unit 500 to execute the command stored in the storage means 50a, the control unit 600 tentatively elapses a first predetermined time until a new trigger word is input by voice. Even if the voice processing unit 200 outputs the text data by then, the search unit 300 may not be instructed to search for music using the text data as a search word.

The above-described embodiment is presented as an example and does not limit the scope of the invention. The above configurations can be implemented in appropriate combinations, and various omissions, replacements, and changes can be made without departing from the gist of the invention. The above-described embodiment and its modifications are included in the scope and gist of the invention, as well as in the scope of the invention described in the claims and the equivalent scope thereof.
