<First Embodiment>
A first embodiment of the present invention will be described with reference to the drawings.

  In the first embodiment of the present invention, an information processing apparatus such as a smart speaker (AI (Artificial Intelligence) speaker) can recognize voice and perform various operations corresponding to the voice. For example, the information processing apparatus can recognize a specific voice command (for example, “Hello!”) From the user and start in response to the specific voice command. The activation of the information processing apparatus is to change the information processing apparatus from the sleep state to the active state. Details of the specific voice command will be described later.

  Such an information processing apparatus may recognize not only a human voice but also a voice emitted from a television, a radio, a PC, or the like. Therefore, the information processing apparatus may be activated by a specific voice command issued by a television or the like.

  In particular, when an advertisement broadcast (information so-called CM (Commercial Message)) of an information processing device (smart speaker) is performed on a television, radio, or distribution video, a specific information is transmitted in order to inform the viewer of the operation of the information processing device. A situation in which a voice command must be issued is assumed. In such a case, there is an increased risk that the information processing apparatus is activated by a specific voice command issued in an advertisement broadcast on a television or the like.

  FIG. 1 is a diagram for explaining a state of a conventional information processing apparatus. In FIG. 1, an information processing apparatus 10 is a smart speaker that is actually installed in a room or the like. In the example of FIG. 1, an advertisement broadcast (CM) of an information processing device (smart speaker) is broadcast on the television 20. Specifically, the television 20 broadcasts “a scene where the character 30 is issuing a specific voice command“ Hello! ”To the information processing apparatus 10A” as an advertisement broadcast. 1, the information processing apparatus 10 </ b> A is an information processing apparatus in an advertisement broadcast and is virtual.

  When such an advertisement broadcast is broadcast by the television 20, the information processing apparatus 10 actually installed in a room or the like recognizes a specific voice command “Hello!” Output from the television 20, The information processing apparatus 10 starts up. In other words, the information processing apparatus 10 transitions from the sleep state to the active state (the “ON” state in FIG. 1).

  Then, once the information processing apparatus 10 is activated, the information processing apparatus 10 enters an active state, and thus receives instructions for executing various processes by voice. Therefore, there arises a problem that the information processing apparatus 10 reacts to various sounds emitted from a television or the like and executes a process unintended by the user.

  Therefore, in the first embodiment of the present invention, a predetermined sound is included in an advertisement broadcast (CM) broadcast on a television or the like. For example, a company that sells the information processing apparatus 10 includes a predetermined sound in an advertisement broadcast (CM) of the information processing apparatus 10. Then, the information processing apparatus 10 is configured to stop the activation process for a predetermined period even when a specific voice command is subsequently recognized when a predetermined sound is detected. Details of the predetermined sound and the predetermined period will be described later.

  FIG. 2 is a diagram for explaining the state of the information processing apparatus 10 according to the first embodiment of the present invention. In FIG. 2, the television 20 broadcasts an advertisement broadcast including a predetermined sound 40. The content of the advertisement broadcast is the same as that of the advertisement broadcast illustrated in FIG.

  When such an advertisement broadcast is broadcast by the television 20, the information processing apparatus 10 actually installed in a room or the like detects a predetermined sound 40. Then, the information processing apparatus 10 stops the activation process of the information processing apparatus 10 for a predetermined period even if it recognizes a specific voice command “Hello!” After detecting a predetermined sound. That is, the information processing apparatus 10 sets a predetermined period after detecting a predetermined sound as a dead period in which the information processing apparatus 10 is not activated even when a specific voice command is recognized. The information processing apparatus 10 does not start even when a specific voice command is recognized during the dead period. For example, in FIG. 2, even if a specific voice command is issued from the television 20 in a predetermined period after detecting a predetermined sound, the information processing apparatus 10 is in the sleep state (the “OFF” state in FIG. 2). Remain and do not transition to the active state.

  As a result, since the information processing apparatus 10 according to the first exemplary embodiment of the present invention maintains the sleep state, the information processing apparatus 10 does not respond to various sounds emitted from a television or the like, and prevents a process unintended by the user from being executed. it can.

(System configuration)

The information processing apparatus 10 is, for example, a smart speaker (AI speaker). The smart speaker has a voice interactive function, and can execute a predetermined process, for example, when a user gives a voice instruction. The predetermined process is, for example, starting up the information processing apparatus 10. The activation of the information processing apparatus 10 is a process for causing the information processing apparatus 10 in the sleep state to transition to the active state. The sleep state is a state where processing of the information processing apparatus 10 is restricted. For example, in the sleep state, the processing of the information processing apparatus 10 is limited to only processing that accepts voice input. Then, in the sleep state, the information processing apparatus 10 does not transition to the active state unless it recognizes a specific voice command by voice input.

  On the other hand, the active state is a state in which the information processing apparatus 10 can execute various processes. The user can instruct the information processing apparatus 10 in the active state to execute various processes by voice. The various processes are, for example, a process of playing music, a search process using a search engine on the Internet, and a product purchase process on various WEB sites. For example, the information processing apparatus 10 executes a process of playing music in response to a voice instruction “play music” from the user.

The specific voice command may be referred to as a wake word, a hot word, a call, or the like. Further, as described above, the activation of the information processing apparatus 10 is a process of causing the information processing apparatus 10 in the sleep state to transition to the active state.

  The specific voice command is a predetermined phrase and is a phrase that the user calls to activate the information processing apparatus 10. For example, the specific voice command is “Hello”, “Ok Computer”, or the like, and may be any word or phrase. Further, the specific voice command may be a combination of a plurality of words (for example, “Ok Computer”). Further, the specific voice command may be a command that repeats a phrase multiple times (for example, “Hello” is repeated three times). Further, the specific voice command may be appropriately changed by the user.

  Further, the voice input may instruct the information processing apparatus 10 in the active state to execute various processes. For example, the input / output unit 103 can accept voice instructions such as “Play music” and “What is the weather today?”. The input by voice is not limited to these examples, and any input may be used.

  Furthermore, the input / output unit 103 can accept input of a predetermined sound (including sound data). The predetermined sound is, for example, a predetermined sound logo included in the advertisement broadcast. For example, a predetermined sound logo determined in advance among the plurality of sound logos is set as the predetermined sound.

  The sound logo is a sound such as a melody, sound effect, song, or voice attached to a company or a product of the company in an advertisement broadcast (CM) such as television, radio, or distribution video. The sound logo may be a short sound such as several seconds, for example, may be a long sound of about several tens of seconds flowing from the start to the end of advertisement broadcasting, and may be any length.

  The predetermined sound is not limited to the sound logo, and may be a predetermined melody, sound effect, song, or voice. The predetermined sound does not need to be heard by humans, and may be any sound information such as a high frequency such as a mosquito sound as long as the information can be detected by the information processing apparatus 10. Further, the predetermined sound may have any length.

  Note that when a predetermined sound is detected, the information processing apparatus 10 stops starting the information processing apparatus 10 for a predetermined period, even if a specific voice command is received thereafter. Specifically, when a predetermined sound is detected, the information processing apparatus 10 in the sleep state does not transition to the active state even if a predetermined voice command “Hello!” Is received for a predetermined period.

  The display unit 104 is, for example, a liquid crystal display or OELD. In addition, the display part 104 is not limited to these examples, A head mounted display (HMD) etc. may be sufficient. The display unit 104 can display display data such as images, text information, and 3D (three dimensional) according to display data written in the frame buffer.

  The storage unit 105 has a function of storing various programs and various data necessary for the information processing apparatus 10 to operate. The storage unit 105 is realized by various storage media such as an HDD, an SSD, and a flash memory.

For example, the detection unit 112 detects a predetermined sound logo included in an advertisement broadcast on a television, radio, video distribution service, or the like. The detection unit 112 can detect a predetermined sound regardless of recognition of a specific voice command by the recognition unit 110.

  The activation unit 111 has a function of activating the information processing apparatus 10 in response to the recognition unit 110 recognizing a specific voice command. Specifically, in response to the recognition unit 110 recognizing a specific voice command, the activation unit 111 causes the information processing apparatus 10 in the sleep state to transition to the active state. Note that, as described above, the sleep state is a state in which the processing of the information processing apparatus 10 is restricted, and is a state in which, for example, the state is restricted to only processing that accepts input by voice. On the other hand, the active state is a state in which the information processing apparatus 10 can execute various processes. For example, the active state is a state in which an instruction to execute various processes by voice can be received from the user.

  Further, when detecting a predetermined sound, the activation unit 111 stops a process (activation process) for activating the information processing apparatus 10 in response to a specific voice command for a predetermined period. That is, when detecting a predetermined sound, the activation unit 111 does not execute the process of transitioning the information processing apparatus 10 in the sleep state to the active state even if a predetermined voice command “Hello!” Is received for a predetermined period. .

  The predetermined period is, for example, the length of an advertisement broadcast (CM) including a predetermined sound, such as 30 seconds or 1 minute. Here, it is the time of the advertisement broadcast that the TV or the like is likely to issue a specific voice command. Therefore, the activation unit 111 sets the length of the advertisement broadcast on a television or the like as a predetermined period (that is, a dead period) and recognizes a specific voice command during the predetermined period (dead period). The device 10 is not activated. The predetermined period is not limited to these examples, and may be set to any length, for example, 5 minutes.

  Thereafter, the recognition unit 110 recognizes a specific voice command (S101). For example, the recognition unit 110 recognizes a predetermined voice command “Hello!”.

  In response to the recognition unit 110 recognizing a predetermined voice command, the activation unit 111 determines whether or not a predetermined period has elapsed since the detection unit 112 detected a predetermined sound (S102).

  When the predetermined period has elapsed (YES in S102), the activation unit 111 activates the information processing apparatus 10 (S103). Specifically, the activation unit 111 causes the information processing apparatus 10 in the sleep state to transition to the active state. On the other hand, when the predetermined period has not elapsed (NO in S102), the activation unit 111 stops the activation process of the information processing apparatus 10 (S104). Specifically, the activation unit 111 does not execute the process of causing the information processing apparatus 10 in the sleep state to transition to the active state.

  As described above, in the first embodiment of the present invention, when the information processing apparatus 10 detects a predetermined sound, even if it recognizes a specific voice command thereafter, the information processing apparatus 10 Stop the startup process. As a result, the information processing apparatus 10 can prevent the information processing apparatus 10 from being erroneously activated by a specific voice command issued from a television or the like. Further, since the information processing apparatus 10 maintains the sleep state, the information processing apparatus 10 does not react to various sounds emitted from a television or the like, and can prevent a process unintended by the user from being executed.

  As described above, the information processing apparatus 10 can erroneously start the information processing apparatus 10 by detecting the predetermined sound. However, the detection of the predetermined sound is lower in cost than the case of identifying by the speaker recognition technology. It is feasible. Therefore, the information processing apparatus 10 according to the first exemplary embodiment of the present invention can reduce the erroneous start of the speaker due to a specific voice command from a television or the like at low cost. Further, the information processing apparatus 10 according to the first exemplary embodiment of the present invention can determine whether or not activation is necessary depending on the presence or absence of a predetermined sound, and does not need to register a user who operates the information processing apparatus 10 in advance.

  As described above, in the first modification of the first embodiment of the present invention, the information processing apparatus 10 detects a predetermined sound and registers it in advance even within a predetermined period from the detection of the predetermined sound. In response to a specific voice command issued by the user, the information processing apparatus 10 is activated. For this reason, the information processing apparatus 10 does not stop at all even within a predetermined period after detection of a predetermined sound, and can be started by a user registered in advance. As a result, if the user is registered in advance, the information processing apparatus 10 can be activated at any time, and convenience can be improved.

(Modification 2)
In the second modification, in addition to the predetermined sound, the information processing apparatus 10 detects the direction in which the predetermined sound is emitted, thereby recognizing a specific voice command issued from other than the direction. This is a mode in which the processing apparatus 10 is activated.

  The detection unit 112 of the information processing apparatus 10 in Modification 2 detects the direction in which the predetermined sound is emitted in addition to the predetermined sound. That is, the direction of the sound source of a predetermined sound is detected. The direction of the sound source can be detected using, for example, a method based on time difference detection of a sound signal, a method of scanning a directional beam (beam forming technique), a method of obtaining a spatial frequency, or the like. In addition, the process in which the detection part 112 detects the direction in which the predetermined sound was emitted is the same as the process of the information processing apparatus 10 in the 2nd Embodiment of this invention demonstrated below.

  The activation unit 111 receives a specific voice command from the direction in which the predetermined sound detected by the detection unit 112 is emitted (that is, the specific voice command from the direction in which the predetermined sound is generated). However, the activation processing of the information processing apparatus 10 is not performed. That is, the activation unit 111 sets the direction in which the predetermined sound detected by the detection unit 112 is emitted as the insensitive direction, and even if a specific voice command is received from the insensitive direction, the activation process of the information processing apparatus 10 is performed. Do not do.

  The predetermined sound is included in the advertisement broadcast broadcast on the television or the like, and the direction in which the predetermined sound is emitted is the direction in which the television or the like is installed. A specific voice command issued from the direction in which the television or the like is installed is highly likely to be issued from the television or the like. Therefore, in the second modification, the activation unit 111 sets the direction in which the television or the like is installed as the insensitive direction, and does not activate the information processing apparatus 10 for a specific voice command issued from the direction.

  On the other hand, the activation unit 111 receives a specific voice command from a direction other than the direction in which the predetermined sound detected by the detection unit 112 is emitted (that is, the specific voice command from a direction other than the direction in which the predetermined sound is generated). When the information processing apparatus 10 is recognized, an activation process of the information processing apparatus 10 is executed. That is, the activation unit 111 activates the information processing apparatus 10 in response to a specific voice command issued from a direction other than the dead direction.

  As described above, in the second modification of the first embodiment of the present invention, the information processing apparatus 10 activates the information processing apparatus 10 in response to a specific voice command issued from the direction in which the television or the like is installed. By not doing so, it is possible to prevent the information processing apparatus 10 from being erroneously activated by a specific voice command issued from a television or the like. In addition, the information processing apparatus 10 activates the information processing apparatus 10 in response to a specific voice command issued from a direction other than the direction in which the television or the like is installed, and therefore, within a predetermined period from detection of a predetermined sound. However, it does not become impossible to start up at all, and convenience can be improved.

(Modification 3)
The modified example 3 is a form in which a plurality of types of predetermined sounds exist and a predetermined period for stopping the activation processing of the information processing apparatus 10 is set for each of the plurality of types of predetermined sounds. .

  The predetermined sound is, for example, a predetermined sound logo, and is included in an advertisement broadcast broadcast on a television or the like. The predetermined period is, for example, the length of the advertisement broadcast. Here, the length of the advertisement broadcast varies depending on the time zone (for example, morning and night) when the advertisement broadcast is broadcast and the medium (for example, television, radio, video distribution, etc.) that broadcast the advertisement broadcast. The length is set. For example, an advertisement broadcast that is broadcast at noon or late at night may be longer than an advertisement broadcast that is broadcast in the morning or evening. In addition, advertisement broadcasts for video distribution may be longer than advertisement broadcasts on television and radio. For other reasons as well, the length of the advertisement broadcast is set to various lengths. Therefore, it is necessary to change the predetermined period according to the length of the advertisement broadcast. If the predetermined period is not changed according to the length of the advertisement broadcast, the predetermined period may be shorter than the length of the advertisement broadcast. In this case, there is a case where the predetermined period ends even though the advertisement broadcast continues, and in such a case, the information processing apparatus 10 may be erroneously started by a specific voice command broadcast in the advertisement broadcast. Because.

  Therefore, in the third modification of the first embodiment of the present invention, a predetermined period for stopping the activation process of the information processing apparatus 10 is set for each of a plurality of types of predetermined sounds. Based on the length of the advertisement broadcast, a predetermined sound to be included in the advertisement broadcast is determined. Specifically, a company that sells the information processing apparatus 10 includes a predetermined sound in which a predetermined period longer than the length of the advertisement broadcast is set in the advertisement broadcast. Thus, the activation unit 111 of the information processing apparatus 10 can stop the activation process of the information processing apparatus 10 for a predetermined period corresponding to a predetermined sound, that is, a period longer than the length of the advertisement.

  The storage unit 105 stores information in which each of a plurality of types of predetermined sounds is associated with a predetermined period. For example, the storage unit 105 stores information in which a predetermined period of 15 seconds is associated with one predetermined sound, and a predetermined period of 30 seconds is associated with another predetermined sound. Memorize the added information. Note that 15 seconds and 30 seconds are merely examples, and the predetermined period (dead period) may be any length.

  The activation unit 111 identifies a predetermined period corresponding to the predetermined sound detected by the detection unit 112 with reference to the storage unit 105. And the starting part 111 stops the starting process of the information processing apparatus 10, even if the recognition part 110 recognizes a specific voice command for the specified predetermined period.

  As described above, in the third modification of the first embodiment of the present invention, a predetermined period for stopping the activation process is set for each of a plurality of types of predetermined sounds. For this reason, for example, by determining a predetermined sound to be included in the advertisement broadcast based on the length of the advertisement broadcast, the information processing apparatus can be used for a predetermined period corresponding to the predetermined sound, that is, a period longer than the advertisement length. 10 start-up processes can be stopped. As a result, it is possible to prevent the predetermined period from becoming shorter than the length of the advertisement broadcast, and to reduce the erroneous start of the information processing apparatus 10 due to a specific voice command issued from a television or the like. Is possible.

(Modification 4)
In the modified example 4, the timing for detecting a predetermined sound (for example, a predetermined sound logo) and the timing for starting the stop of the information processing apparatus 10 in response to the detection of the predetermined sound are mutually different. It is a form when different (not continuous).

  If the insensitive period (that is, the predetermined period) of the information processing apparatus 10 is long, the time for which the startup process of the information processing apparatus 10 is stopped becomes long, and convenience may be reduced. On the other hand, the predetermined sound is, for example, a predetermined sound logo, and is included in an advertisement broadcast (CM) of the information processing apparatus 10 by a company that sells the information processing apparatus 10. Therefore, a company that sells the information processing apparatus 10 has a high possibility of grasping the content of the advertisement broadcast (CM). That is, a company that sells the information processing apparatus 10 can grasp at which timing in the advertisement broadcast (CM) a specific voice command is issued. In this case, a company that sells the information processing apparatus 10 matches the dead period (predetermined period) of the information processing apparatus 10 with the timing at which a specific voice command is issued in an advertisement broadcast (CM). Can be shortened. As a result, the convenience of the information processing apparatus 10 can be improved.

  Specifically, the start timing of a predetermined period (dead period) for stopping the activation process of the information processing apparatus 10 is set for each of a plurality of types of predetermined sounds. A company that sells the information processing apparatus 10 starts a dead period of the information processing apparatus 10 at a timing when a specific voice command is issued in an advertisement broadcast (CM) among a plurality of types of predetermined sounds. The predetermined sound to be selected is selected, and the selected predetermined sound is included in the advertisement broadcast. In this case, the predetermined period (dead period) may be set according to the length at which a specific voice command is issued. In that case, only a time zone in which a specific voice command is issued in the advertisement broadcast (CM) can be set as a predetermined period (dead period).

  In addition, advertisement broadcasting (CM) from the same company may be continuously broadcast on a television or the like. For example, a company that sells the information processing apparatus 10 has created a plurality of advertisement broadcasts (CMs) for the information processing apparatus 10, followed by another pattern of advertisement broadcasts (CM). It is assumed that the advertising effect is enhanced by broadcasting the broadcast (CM). In such a case, it is possible to broadcast continuously (or with another company's advertisement broadcast (CM)) from the timing at which a specific voice command is issued in the advertisement broadcast (CM) broadcast first. It is assumed that the insensitive period (predetermined period) of the information processing apparatus 10 should be continued until a specific voice command is issued in the advertisement broadcast (CM) of this pattern.

  In this case, a company that sells the information processing apparatus 10 separates the insensitive period (predetermined period) of the information processing apparatus 10 from the timing (time) at which a specific voice command is issued in the first advertisement broadcast (CM). This is continued until a specific voice command is issued in the advertisement broadcast (CM) of the pattern. As a result, the information processing apparatus 10 is insensitive to a specific voice command issued in another pattern of the advertisement broadcast (CM) that is subsequently broadcast by the predetermined sound detected in the first advertisement broadcast (CM). The activation process of the information processing apparatus 10 can be stopped.

  As in the above example, the timing for detecting a predetermined sound (for example, a predetermined sound logo) and the timing for stopping the activation of the information processing apparatus 10 in response to the detection of the predetermined sound are mutually It may be desirable to be different. Note that the above example is merely an example, and various cases are assumed when it is desirable to make the timing for detecting a predetermined sound different from the timing for stopping the activation of the information processing apparatus 10.

  The storage unit 105 stores information in which each of a plurality of types of predetermined sounds is associated with the start timing of a predetermined period (dead period). For example, the storage unit 105 stores, for one predetermined sound, information indicating that it is 10 seconds after the one predetermined sound is detected as the start timing of the predetermined period (dead period). Is done. That is, one predetermined sound does not become a dead period (predetermined period) until 10 seconds elapses after the one predetermined sound is detected. Note that 10 seconds later is merely an example, and the start timing of the predetermined period (dead period) may be any number of seconds after the detection of the predetermined sound (units are arbitrary, such as how many minutes later). .

  Similarly to the third modification, the storage unit 105 may set a predetermined period for stopping the activation process of the information processing apparatus 10 for each of a plurality of types of predetermined sounds. For example, the storage unit 105 stores information in which a predetermined period of 15 seconds is associated with one predetermined sound. As a result, the information processing apparatus 10 that has detected one predetermined sound starts a predetermined period (insensitive period) 10 seconds after the one predetermined sound is detected, and thereafter, the predetermined period (insensitive period). Period) continues for 15 seconds.

  Note that 15 seconds later is merely an example, and the predetermined period (dead period) may be any length. Further, the predetermined period may be set to a length at which a specific voice command is issued in an advertisement broadcast (CM), for example. Further, for example, when a specific voice command is issued a plurality of times in an advertisement broadcast (CM), the predetermined period may be set to a length including a timing at which the last specific voice command is ended.

  Note that the storage unit 105 may set an end timing in addition to the start timing of a predetermined period (dead period) for each of a plurality of types of predetermined sounds. For example, the storage unit 105 starts the predetermined period (insensitive period) for another predetermined sound 10 seconds after the detection of the other predetermined sound, and the predetermined period (insensitive period) Information indicating that the end is 30 seconds after the detection of the other predetermined sound is stored. In this case, the information processing apparatus 10 that has detected the other predetermined sound starts a predetermined period (dead period) 10 seconds after the detection of the other predetermined sound, and 30 times after the detection of the other predetermined sound. The predetermined period (dead period) ends after 2 seconds.

  Note that the time after 30 seconds is merely an example, and the end timing of the predetermined period (dead period) may be any number of seconds after the detection of the predetermined sound (units are arbitrary, such as after several minutes). . The end timing of the predetermined period (dead period) may be set to a timing at which the generation of a specific voice command ends in the advertisement broadcast (CM). Also, the end timing of the predetermined period (dead period) is set to the timing at which the last specific voice command is ended, for example, when a specific voice command is issued a plurality of times in an advertisement broadcast (CM). Also good.

  The activation unit 111 identifies the start timing of a predetermined period (dead period) corresponding to the predetermined sound detected by the detection unit 112 with reference to the storage unit 105. Then, the activation unit 111 stops the activation process of the information processing apparatus 10 even after the recognition unit 110 recognizes a specific voice command after the start timing of the predetermined period (dead period).

  In addition, the activation unit 111 identifies a predetermined period corresponding to the predetermined sound detected by the detection unit 112 with reference to the storage unit 105. The activation unit 111 performs the activation process of the information processing apparatus 10 even when the recognition unit 110 recognizes a specific voice command within a predetermined period after the start timing of the predetermined period (dead period). To stop.

  The activation unit 111 may specify the end timing of the predetermined period (dead period) corresponding to the predetermined sound detected by the detection unit 112 with reference to the storage unit 105. And even if the recognition part 110 recognizes a specific voice command from the timing of the start of a predetermined period (dead period) to the timing of the end of a predetermined period (dead period), the starting part 111 is information processing apparatus. 10 start-up processing is stopped.

  As described above, in the fourth modification of the first embodiment of the present invention, the start of the information processing apparatus 10 is stopped in response to detection of a predetermined sound for each of a plurality of types of predetermined sounds. The timing to start is set. The timing for detecting the predetermined sound and the timing for stopping the activation of the information processing apparatus 10 in response to the detection of the predetermined sound can be made different from each other. As a result, the dead period (predetermined period) can be shortened by stopping the activation process of the information processing apparatus 10 in accordance with the timing (time) at which a specific voice command is issued in the advertisement broadcast (CM). . In addition, a dead period (predetermined period) can be set across different advertisement broadcasts (CM) according to the broadcast mode of the advertisement broadcast (CM). As described above, in the fourth modification, the start timing and end timing of the predetermined period (dead period) for stopping the activation processing of the information processing apparatus 10 can be freely set, and convenience can be improved.

<Second Embodiment>
A second embodiment of the present invention will be described with reference to the drawings.

  In the second embodiment of the present invention, a predetermined sound is included in an advertisement broadcast (CM) broadcast on a television or the like, and the information processing apparatus 10 emits the predetermined sound together with the predetermined sound. It is an embodiment in the case of detecting a direction. And even if the information processing apparatus 10 recognizes a specific voice command from the direction in which the predetermined sound is emitted, the information processing apparatus 10 does not execute the activation process of the information processing apparatus.

  FIG. 7 is a diagram for explaining the state of the information processing apparatus 10 according to the second embodiment of the present invention. In FIG. 7, the television 20 broadcasts an advertisement broadcast including a predetermined sound 40. The content of the advertisement broadcast is the same as that of the advertisement broadcast illustrated in FIG.

  When such an advertisement broadcast is broadcast by the television 20, the information processing apparatus 10 actually installed in a room or the like detects a predetermined sound 40 and a direction in which the predetermined sound 40 is emitted. In the example of FIG. 7, the direction 60 is detected as the direction in which the predetermined sound is emitted. As shown in FIG. 2, the direction in which the predetermined sound 40 is emitted may be detected as a certain range (direction 60), or may be detected as a certain direction (that is, a certain point).

  In this case, even if the information processing apparatus 10 recognizes a specific voice command from the direction in which the predetermined sound is emitted, the information processing apparatus 10 stops the activation process of the information processing apparatus 10. That is, the information processing apparatus 10 sets the direction in which the predetermined sound is emitted as a dead direction that does not activate the information processing apparatus 10 even when a specific voice command is recognized, and the specific voice command from the dead direction. Does not start up the information processing apparatus 10. For example, in FIG. 2, even if a specific voice command is issued from the direction in which a predetermined sound is emitted, that is, the direction of the television 20, the information processing apparatus 10 is in the sleep state (the “OFF” state in FIG. 7). Remain and do not transition to the active state.

  As a result, the information processing apparatus 10 according to the first exemplary embodiment of the present invention maintains a sleep state even when a specific voice command issued from the television 20 or the like is recognized, and thus reacts to various voices emitted from the television or the like. Thus, it is possible to prevent a process unintended by the user from being executed.

(System configuration)
The configuration example of the information processing system in the second embodiment of the present invention is the same as the configuration example of the information processing system in the first embodiment of the present invention shown in FIG.

(Configuration example of information processing device)
The configuration example of the information processing apparatus in the second embodiment of the present invention is the same as the configuration example of the information processing apparatus in the first embodiment of the present invention shown in FIG.

  In the second embodiment of the present invention, the detection unit 112 detects the direction in which the predetermined sound is emitted in addition to the predetermined sound. That is, the direction of the sound source of a predetermined sound is detected. The direction of the sound source can be detected using, for example, a method based on time difference detection of a sound signal, a method of scanning a directional beam (beam forming technique), a method of obtaining a spatial frequency, or the like.

  8 and 9 are diagrams for explaining an operation of detecting a direction in which a predetermined sound is emitted by the detection unit 112. FIG. 8 and 9, the television 20 broadcasts an advertisement broadcast including a predetermined sound.

  As illustrated in FIG. 8, the detection unit 112 detects α [degrees] in the upward direction with respect to a direction in which a predetermined sound is emitted with reference to a plane 13 that is horizontal to the ground 12 passing through a certain point 11 of the information processing apparatus 10. ] Is detected as a range of β [degrees] in the downward direction. In the example of FIG. 8, the detection unit 112 detects a range 60A from the upward direction α [degrees] to the downward direction β [degrees] as a direction in which a predetermined sound is emitted. Note that the direction in which the predetermined sound is emitted may be indicated only by an upward angle with respect to the surface 13, or may be indicated only by an downward angle with respect to the surface 13.

  In addition, as illustrated in FIG. 9, the detection unit 112 detects γ [ Degree], it is detected as a range of δ [degree] in the left direction. In the example of FIG. 9, the detection unit 112 detects a range 60 </ b> B from the right direction γ [degree] to the left direction δ [degree] as a direction in which a predetermined sound is emitted. It should be noted that the direction in which the predetermined sound is emitted may be indicated by only the leftward angle with respect to the surface 14 or may be indicated only by the rightward angle with respect to the surface 14.

  As described above, the detection unit 112 can detect the direction in which a predetermined sound is emitted as a certain range. Note that the detection unit 112 may detect a direction in which a predetermined sound is emitted as a certain direction (that is, a certain point).

  The detection unit 112 may detect the position of an object that has emitted a predetermined sound. In the example of FIG. 8, the detection unit 112 detects, for example, a range of the distance in the vertical direction from the ground 12 of the object that has emitted a predetermined sound (in the example of FIG. 8, the range of the height h and the height H). Is possible. In the example of FIG. 9, the detection unit 112 can detect, for example, a distance range in the horizontal direction on the ground 12 of the object that has emitted a predetermined sound (in the example of FIG. 9, a range of distance l and distance L). It is. That is, the detection unit 112 can detect the position of the object that has emitted the predetermined sound as the distance from the own device (the information processing device 10).

  Note that the detection unit 112 may detect the position of an object that emits a predetermined sound as a relative position in a space (for example, a room) in which the information processing apparatus 10 is installed.

  Even if the activation unit 111 receives a specific voice command from the direction in which the predetermined sound detected by the detection unit 112 is emitted (that is, recognizes the specific voice command from the direction in which the predetermined sound is emitted). However, the activation processing of the information processing apparatus 10 is not performed. That is, the activation unit 111 sets the direction in which the predetermined sound detected by the detection unit 112 is emitted as the insensitive direction, and even if a specific voice command is received from the insensitive direction, the activation process of the information processing apparatus 10 is performed. Do not do.

  Specifically, the activation unit 111, when the direction in which the predetermined voice command recognized by the recognition unit 110 is issued matches the direction in which the predetermined sound detected by the detection unit 112 is emitted, The activation process of the information processing apparatus 10 is not executed. Note that “match” means that the direction in which the predetermined voice command recognized by the recognition unit 110 is issued matches or is included in the direction in which the predetermined sound detected by the detection unit 112 is emitted.

  In addition, once the activation unit 111 detects the direction in which the predetermined sound is emitted, the activation unit 111 receives a specific voice command from that direction thereafter (that is, from the direction in which the predetermined sound is emitted thereafter). Even if a specific voice command is recognized, the information processing apparatus 10 is not activated. That is, unlike the first embodiment, the period for stopping the activation process of the information processing apparatus 10 is not limited to a predetermined period, and the activation process is continuously stopped. There is a high possibility that the installation position of the information processing apparatus 10 such as a smart speaker or the installation position of a television or the like is fixed. Therefore, once the direction in which the predetermined sound is emitted is detected, the information processing apparatus 10 is not continuously activated so that the information processing apparatus 10 frequently executes the process of detecting the direction. And the processing load on the information processing apparatus 10 can be reduced.

  The predetermined sound is included in the advertisement broadcast broadcast on the television or the like, and the direction in which the predetermined sound is emitted is the direction in which the television or the like is installed. A specific voice command issued from the direction in which the television or the like is installed is highly likely to be issued from the television or the like. Therefore, the activation unit 111 sets the direction in which the television or the like is installed as the insensitive direction, and does not activate the information processing apparatus 10 for a specific voice command issued from the direction.

  On the other hand, the activation unit 111 receives a specific voice command from a direction other than the direction in which the predetermined sound detected by the detection unit 112 is emitted (that is, the specific voice command from a direction other than the direction in which the predetermined sound is generated). When the information processing apparatus 10 is recognized, an activation process of the information processing apparatus 10 is executed. That is, the activation unit 111 activates the information processing apparatus 10 in response to a specific voice command issued from a direction other than the dead direction.

  In addition, when the detection unit 112 detects the position of an object that emits a predetermined sound, the activation unit 111 recognizes a specific voice command issued from the position of the object, even if it recognizes a specific voice command. Does not perform startup processing. On the other hand, when the activation unit 111 recognizes a specific voice command issued from a position other than the position of the object detected by the detection unit 112, the activation unit 111 activates the information processing apparatus 10.

  In the second embodiment of the present invention, the predetermined sound may be, for example, a predetermined sound logo included in advertisement broadcasting. For example, a predetermined sound logo determined in advance among the plurality of sound logos is set as the predetermined sound. The predetermined sound is not limited to the sound logo, and may be a predetermined melody, sound effect, song, or voice. The predetermined sound does not need to be heard by humans, and may be any sound information such as a high frequency such as a mosquito sound as long as the information can be detected by the information processing apparatus 10. Further, the predetermined sound may have any length.

(Operation example of information processing device)
FIG. 10 is a flowchart illustrating an operation example of the information processing apparatus 10 according to the second exemplary embodiment of the present invention. Note that the operation example illustrated in FIG. 10 is merely an example, and the operation of the information processing apparatus 10 is not limited to the operation example illustrated in FIG.

  The detection unit 112 of the information processing apparatus 10 detects a predetermined sound and a direction in which the predetermined sound is emitted (S200). For example, the recognition unit 110 detects a predetermined sound logo and a direction in which the predetermined sound logo is emitted.

  Thereafter, the recognition unit 110 recognizes the specific voice command and the direction in which the specific voice command is issued (S201). For example, the recognition unit 110 recognizes a predetermined voice command “Hello!” And a direction in which the predetermined voice command is issued.

  Next, the activation unit 111 determines whether the direction in which the predetermined voice command recognized by the recognition unit 110 is emitted matches the direction in which the predetermined sound detected by the detection unit 112 is emitted. (S202).

  When the direction in which the predetermined voice command recognized by the recognition unit 110 is emitted matches the direction in which the predetermined sound detected by the detection unit 112 is emitted (YES in S202), the activation unit 111 The information processing apparatus 10 is not activated (S203).

  On the other hand, when the direction in which the predetermined voice command recognized by the recognition unit 110 is emitted does not match the direction in which the predetermined sound detected by the detection unit 112 is emitted (NO in S202), the activation unit 111 The information processing apparatus 10 is activated (S204).

  As described above, in the second embodiment of the present invention, even when the information processing apparatus 10 recognizes a specific voice command from the direction in which a predetermined sound is emitted, the information processing apparatus starts up. do not do. As a result, the information processing apparatus 10 can prevent the information processing apparatus 10 from being erroneously activated by a specific voice command issued from a television or the like. Further, since the information processing apparatus 10 maintains the sleep state, the information processing apparatus 10 does not react to various sounds emitted from a television or the like, and can prevent a process unintended by the user from being executed.

  As described above, the information processing apparatus 10 can erroneously start the information processing apparatus 10 by detecting the direction in which the predetermined sound is emitted. However, the detection of the direction in which the predetermined sound is generated is performed by speaker recognition. This can be realized at a lower cost compared with the case of identifying by technology. Therefore, the introduction processing device 10 according to the second embodiment of the present invention can reduce the erroneous start of the speaker due to a specific voice command from a television or the like at a low cost. Further, the information processing apparatus 10 can determine whether or not the activation is necessary depending on whether or not a specific voice command is issued from the direction in which the predetermined sound is emitted, and registers a user who operates the information processing apparatus 10 in advance. Since it is not necessary, for example, a person other than the registrant such as a visitor can operate the information processing apparatus 10, and convenience can be improved.

(Modification 1)
The first modification is that the information processing apparatus 10 is a specific voice command issued by a previously registered user even when the information processing apparatus 10 recognizes a specific voice command from the direction in which the predetermined sound is generated. In this example, the information processing apparatus 10 is activated in response.

  The storage unit 105 of the information processing apparatus 10 in Modification 1 stores user voice data in advance. The user's voice data can be stored, for example, by inputting a predetermined phrase including a specific voice command from the user in advance. The predetermined phrase includes, for example, “Hello!”, “Message”, and the like, and the information processing apparatus 10 creates the user's voice data based on the voice input in advance by the user.

  Based on the user's voice data stored in the storage unit 105, the recognition unit 110 of the control unit 101 determines whether the recognized specific voice command is issued from a user registered in advance. Note that determining whether or not a specific voice command has been issued from a pre-registered user can be realized by, for example, comparing feature parts and generated from a television or the like using speaker identification technology. This can be realized at a low cost compared to distinguishing between a voice and a human voice.

  Even when the detection unit 112 detects the direction of a predetermined sound and recognizes a specific voice command from the direction in which the predetermined sound is emitted, the activation unit 111 has the recognition unit 110 registered in advance. In response to recognizing that the voice command is a specific voice command issued by the user, the information processing apparatus 10 is activated. That is, when the recognition unit 110 recognizes a specific voice command issued from a user registered in advance, the activation unit 111 causes the information processing apparatus 10 in the sleep state to transition to the active state.

  FIG. 11 is a diagram for explaining another state of the information processing apparatus 10 according to the second embodiment of the present invention. In FIG. 11, the user 50 is a registered user, and the voice data of the user 50 is stored in advance in the storage unit 105 of the information processing apparatus 10.

  In FIG. 11, the television 20 broadcasts an advertisement broadcast including a predetermined sound. The content of the advertisement broadcast is the same as that of the advertisement broadcast illustrated in FIG. For this reason, the information processing apparatus 10 actually installed in a room or the like detects a predetermined sound. Then, the information processing apparatus 10 does not start up the information processing apparatus 10 even if the information processing apparatus 10 detects a predetermined sound and receives a specific voice command “Hello!” From the direction in which the predetermined sound is emitted. That is, in FIG. 11, even if a specific voice command is issued from the television 20, the information processing apparatus 10 remains in the sleep state and does not transition to the active state.

  However, in FIG. 11, when the user 50 issues a specific voice command “Hello!”, A predetermined sound is emitted in the direction in which the specific voice command “Hello!” Is issued from the user 50.
