The information terminal 1 can display the image (image) by transmitting the image signal to the information terminal 1 through the lobby walkie-talkie 20 .

The control apparatus 40 is installed in the management room E3 of the complex housing 70, for example. The control device 40 is connected to the lobby walkie-talkie 20 via the first trunk line 61 , and is connected to each information terminal 1 via the second trunk line 62 . That is, the control apparatus 40 is comprised so that the communication between each information terminal 1 and the lobby intercom 20 may be relayed.

Each of the plurality of door sub-machines 30 is installed at the door outside the household E2 of the complex house 70, for example. Each door sub-machine 30 is connected to the corresponding information terminal 1 via the connecting line 64 . Each door sub-machine 30 is configured to communicate with the corresponding information terminal 1 (eg, communication, transmission of video signals, etc.).

In this embodiment, the first trunk line 61, the second trunk line 62, the branch line 63, and the connection line 64 are all twisted pair lines. That is, the first trunk line 61 , the second trunk line 62 , the branch line 63 , and the connection line 64 are actually composed of two electric wires, but they are shown as one line in the drawing. At least one of the first trunk line 61 , the second trunk line 62 , the branch line 63 and the connection line 64 may be an electric wire other than the twisted pair.

The information terminal 1 of this embodiment acquires the voice of the user in the household E2, and performs a voice recognition process on the acquired voice. The information terminal 1 performs control related to the operation of the walkie-talkie system 100 based on the result of the voice recognition processing. That is, the information terminal 1 is configured to be operable by voice. For example, when the information terminal 1 obtains a keyword (control word) for performing control related to the opening and closing of the entrance door 200 (door) provided in the common entrance E1 from the voice of the user in the household E2, the control function is executed. Controls corresponding to words. Specifically, when the information terminal 1 detects "open door" as a control word by voice recognition, control for opening the entrance door 200 (see FIG. 2 ) is performed. Here, the entrance door 200 is configured to be opened and closed by an electronic lock 201 (see FIG. 2 ).

As shown in FIG. 1 , the information terminal 1 of the present embodiment includes a sound pickup unit 202 , a sound recognition unit 33 , a switching unit 34 , and a control processing unit 35 . The audio pickup unit 202 acquires audio including at least the user's voice.

The voice recognition unit 33 performs voice recognition processing based on the audio frequency acquired by the voice pickup unit 202 . When the voice recognition unit 33 recognizes that the set keyword, that is, the trigger word, is included in the sound acquired by the sound pickup unit 202, it performs processing corresponding to the trigger word. Specifically, when the voice recognition unit 33 accepts the trigger word, the control unit 3 forcibly enables the function of the voice recognition unit 33 regardless of the setting of the switching unit 34 .

The switching unit 34 switches between the presence or absence of the restriction of the voice control function. When the restriction of the voice control function is valid, the voice control function is restricted, and when the restriction of the voice control function is invalid, the voice control function is not restricted. The voice control function includes the control processing unit 35 performing processing based on the result of the voice recognition processing by the voice recognition unit 33 . In the present embodiment, the switching unit 34 has a switching flag, and the value of the switching flag is changed according to the presence or absence of the restriction of the voice control function. For example, when the restriction of the sound control function is valid, the switching unit 34 sets the value of the switching flag to "1". When the restriction of the sound control function is invalid, the switching unit 34 sets the value of the switching flag to "0".

Here, the limitation of the sound control function means to limit a part or all of the sound control function. In this embodiment, the voice control function is restricted, that is, the restriction of the voice control function is valid, which means that the control processing unit 35 does not perform processing based on the voice recognition processing result of the voice recognition unit 33 . On the contrary, the voice control function is not restricted, that is, the restriction of the voice control function is invalid, which means that the control processing unit 35 performs processing based on the voice recognition processing result of the voice recognition unit 33 .

By enabling both the functions of the voice recognition unit 33 and the control processing unit 35, the limitation of the voice control function can be lifted.

The switching unit 34 has a switching mode for switching the presence or absence of the restriction of the voice control function. The switching mode includes a manual mode for manual switching and an automatic mode for automatic switching.

When the switching mode is the manual mode, by operating the information terminal 1 by the user, the presence or absence of the restriction of the voice control function can be switched.

When the switching mode is the automatic mode, it is possible to switch whether there is a restriction on the voice control function according to the operation mode of the information terminal 1 . That is, when the switching mode is the automatic mode, the switching unit 34 acquires the operation mode of the information terminal 1 and the like, and switches whether there is a restriction on the voice control function or not based on the acquired operation mode. Here, the action mode includes an at-home mode, an out-of-home mode, a crime prevention mode, a child lock mode, and the like. The at-home mode is the mode in which the occupants of the household E2 are at home. The outgoing mode is the mode when the occupant of the household E2 is not at home. The crime prevention mode is a mode for crime prevention that is set when the resident of the household E2 goes out, and when it is late at night and early in the morning. The child lock mode is a mode in which the operation is locked to prevent misoperation by children. In addition, the detection results of various sensors may be included in the operation mode. When the resident goes out from the household E2, the sound control function is limited, and when the resident in the household E2 is at home, the sound control function is not limited. It is also possible to freely associate with which mode according to which mode is defined in the walkie-talkie system 100 .

The control processing unit 35 has a voice control function that performs control based on the voice recognition result of the voice picked up by the voice pickup unit 202 . The control processing part 35 performs control based on the result of the voice recognition processing of the voice recognition part 33 when the restriction of the voice control function is invalid. Here, the control based on the result of the voice recognition processing may be the control of the functions included in the control processing unit 35 , the control of the call with the lobby intercom 20 , etc., or the effect of unlocking the electronic lock 201 of the entrance door 200 , etc. external control. On the other hand, when the voice control function is restricted, the control processing unit 35 does not perform control based on the voice recognition processing result of the voice recognition unit 33 .

The restriction of switching the voice control function by the switching unit 34 is determined by, for example, using a function such as the walkie-talkie system 100's outgoing mode, or by interlocking with other devices.

In the information terminal 1 of the present embodiment, when the switching unit 34 restricts the voice control function, the control unit 3 restricts the operation of the voice recognition unit 33 . That is, the limitation of the voice control function of the control unit 3 includes disabling the voice recognition function for recognizing voice.

In the information terminal 1 of the present embodiment, the function of the interphone system 100 and the linkage with other devices can be used to limit the voice control function. Therefore, the power consumption can be reduced compared with the case where the sound control function is always turned on.

Furthermore, when the occupant is not in the household E2, the control unit 3 restricts the voice control function, thereby suppressing erroneous operation of the voice control function by a third party, and improving safety.

(2) Composition The configuration of the walkie-talkie system 100 according to the present embodiment will be described. The walkie-talkie system 100 includes an information terminal 1 , a hall walkie-talkie 20 , a door slave 30 , a control device 40 , and a server 60 .

(2-1) Information terminal As shown in FIG. 1 , the information terminal 1 includes a sound pickup unit 202 , a control unit 3 , an operation unit 4 , a notification unit 11 , a memory unit 7 , a first communication unit 8 , a second communication unit 9 , and a third communication unit 10 .

The sound-receiving part 202 may be a device integrated into the walkie-talkie system 100 , a non-integrated device such as a smart speaker, or a portable terminal such as a smart phone. That is, the sound pickup unit 202 only needs to include a device for collecting sound, a communication circuit for transmitting the device for collecting sound to the control unit 3 as an electrical signal, and the like.

The operation part 4 is comprised so that the operation of a user (for example, a resident of each household E2, etc.) may be received. The operation unit 4 has at least a call button. The call button is a button for starting communication with the lobby intercom 20 or the entrance sub-machine 30 (calling with a visitor, etc.) for a call from the lobby intercom 20 or the entrance sub-machine 30 . That is, when the call button is pressed in a state where the first communication unit 8 receives a call signal for calling a resident, a voice call can be made between the lobby intercom 20 or the door handset 30 and the information terminal 1 .

In the operation unit 4 , the user can change the setting state of the information terminal 1 . Specifically, the user can switch the validity and invalidity of the restriction of the sound control function, and switch between the automatic mode and the manual mode. The automatic mode is a mode in which the sound control function is automatically switched between valid and invalid based on whether the occupants in the household E2 are at home or not. For example, when the home mode is switched to the out-of-office mode, the switching unit 34 automatically switches the restriction of the voice control function from invalid to valid. The manual mode is a mode in which the user operates the operation unit 4 or the like to switch between valid and invalid of the restriction of the sound control function.

In addition, when the information terminal 1 is provided with a touch panel display, the touch panel display may also serve as the display unit 6 and the operation unit 4 .

In the present embodiment, the notification unit 11 is configured to have both the output unit 5 and the display unit 6, but is not limited to this configuration. The notification unit 11 may be configured to include one of the output unit 5 and the display unit 6 . That is, the notification unit 11 includes at least one of the output unit 5 and the display unit 6 . The notification unit 11 notifies, for example, that the sound control function is invalid by at least one of sound and display. When the notification part 11 contains a trigger word that is a trigger of voice recognition, such as "I'm back", etc., when the operation of the original voice recognition can be performed, the notification part 11 notifies "voice recognition function is limited" by display or sound.

The memory unit 7 is a memory device for memorizing the program executed by the control unit 3 . The memory part 7 is selected from ROM (Read Only Memory), RAM (random Access Memory: random access memory), or EEPROM (Electrically Erasable Programmable Read Only Memory: Electronically Erasable Programmable Read Only Memory) memory) and other devices.

The first communication unit 8 is a communication interface for communicating with the communication unit 21 of the lobby walkie-talkie 20 . The first communication unit 8 is connected to the control device 40 via the second trunk line 62 , the branch line 63 , and the brancher 50 . The first communication unit 8 transmits an audio signal, a control signal, and the like to the lobby walkie-talkie 20 via the control unit 42 . Furthermore, the first communication unit 8 receives audio signals, video signals, and the like from the lobby walkie-talkie 20 via the control device 40 .

The second communication unit 9 is a communication interface for communicating with the door slave 30 . The second communication unit 9 is connected to the door sub-unit 30 via the connection line 64 . The second communication unit 9 transmits audio signals, control signals, and the like to the door sub-unit 30 , and receives audio signals, video signals, and the like from the door sub-unit 30 .

The third communication unit 10 is a communication interface for communicating with the outside (here, the server 60 ). The third communication unit 10 is connected to the server 60 via the network NT1. The third communication unit 10 transmits audio signals, control signals, and the like to the server 60 , and receives audio signals and the like from the server 60 .

The control unit 3 has a voice control function for performing control based on the voice recognition result of the voice picked up by the sound pickup unit 202 . The control unit 3 restricts the voice control function based on the operation of the information terminal 1 . Below, the function of the control part 3 is demonstrated concretely. As shown in FIG. 1 , the control unit 3 includes a voice processing unit 31 , a voice recognition unit 33 , a switching unit 34 , a control processing unit 35 , a delay processing unit 36 , a display processing unit 37 , and a sending unit 38 .

The audio processing unit 31 acquires the analog audio signal output by the audio pickup unit 202 . The audio processing unit 31 converts the acquired analog audio signal into a digital audio signal. In addition, the audio processing unit 31 is configured to perform a specific filtering process or the like on the audio signal acquired from the audio pickup unit 202 . The sound processing unit 31 includes, for example, an echo canceller. The echo canceller suppresses or removes the echo of the audio signal output from the sound pickup unit 202 .

The voice recognition unit 33 performs voice recognition processing based on the audio signal processed by the voice processing unit 31 . When the voice recognition unit 33 recognizes that the set keyword, ie, the trigger word, is included in the voice acquired by the sound pickup unit 202, it performs processing corresponding to the trigger word.

The switching unit 34 is configured to control the operation of the control processing unit 35 by switching between the valid and the invalid of the switching unit 34 . More specifically, the operation of the control processing unit 35 is controlled by the switching unit 34 switching the switching flag based on the operation of the information terminal 1 . When the switching flag of the switching unit 34 is "1", the function restriction of the control processing unit 35 is valid, and the control processing unit 35 does not perform processing corresponding to the voice recognition result. When the switching flag of the switching unit 34 is "0", the function restriction of the control processing unit 35 is invalid, and the control processing unit 35 performs processing corresponding to the voice recognition result. The operation of the information terminal 1 includes an operation mode, sensor output, and the like.

When the operation mode of the information terminal 1 is the operation mode accompanied by the user entering the facility 70 , the voice control function is enabled, and the control processing unit 35 performs processing based on the recognition result of the voice recognition unit 33 . For example, the operation mode of the information terminal 1 associated with entering the facility 70 is the home mode. When the operation mode of the information terminal 1 is the operation mode accompanied by the user leaving the facility 70, the sound control function is disabled, and the control processing unit 35 does not perform control processing. For example, the operation modes of the information terminal 1 accompanying leaving the facility 70 are the outgoing mode and the crime prevention mode.

The operation of the information terminal 1 includes a setting state set according to an input from the user. Specifically, in the manual mode, according to the manual input from the user, the switching unit 34 switches the validity and the invalidity of the voice recognition function. For example, in the manual mode, the user can switch the action mode from the outgoing mode to the home mode. Therefore, the control processing unit 35 performs control based on the voice recognition result of the voice recognition unit 33 . Also, in the manual mode, the user can switch the operation mode, eg, the home mode, to the outing mode or the crime prevention mode. Therefore, the control processing unit 35 does not perform control based on the voice recognition result of the voice recognition unit 33 .

The control processing unit 35 performs control based on the voice recognition result of the voice recognition unit 33 . Specifically, when the voice control function is effective, the control processing unit 35 performs control based on the voice recognition result of the voice recognition unit 33 . On the other hand, when the voice control function is invalid, the control processing unit 35 does not perform control based on the voice recognition result. In the present embodiment, when the value of the switching flag of the switching unit 34 is "1", the control processing unit 35 does not perform control based on the voice recognition result because the limitation of the voice control function is valid. When the value of the switching flag of the switching unit 34 is "0", the control processing unit 35 performs control based on the voice recognition result because the restriction of the voice control function is invalid.

The control processing unit 35 is configured to control at least a part of the operation of the information terminal 1 and the operation of the equipment controllable by the information terminal 1 based on the voice recognition result of the voice recognition unit 33 .

Further, the control processing unit 35 restricts the audio control function corresponding to the content indicated by the switching flag of the switching unit 34 (valid or invalid of the audio control function) based on the operation mode of the information terminal 1 . For example, when the operation mode is the outing mode or the crime prevention mode, the switching flag of the switching unit 34 is enabled, and the control processing unit 35 does not perform processing corresponding to the voice recognition result. On the other hand, when the operation mode is the home mode, the switching flag of the switching unit 34 is invalid, and the control processing unit 35 performs processing corresponding to the voice recognition result.

When the control processing unit 35 receives an instruction to start communication (communication) with the lobby intercom 20 or the door sub-unit 30 as a communication partner, it controls the operation of the information terminal 1 . For example, the control processing unit 35 controls the first communication between the information terminal 1 and the hall walkie-talkie 20 or the entrance slave 30 in a manner that enables communication between the information terminal 1 and the hall walkie-talkie 20 or the entrance slave 30 . The communication unit 8 and the second communication unit 9 .

The control processing unit 35 controls the operation of the device that can be controlled by the information terminal 1 according to the judgment of the voice recognition unit 33 on whether the audio frequency processed by the voice processing unit 31 contains a control word.

For example, the control processing unit 35 performs processing related to the control of the walkie-talkie system 100 according to whether or not the voice recognition unit 33 has detected a control word. More specifically, when the voice recognition unit 33 determines that the audio processed by the voice processing unit 31 contains the control words, the control processing unit 35 performs processing corresponding to the control words contained in the audio processed by the voice processing unit 31 . For example, during the communication between the information terminal 1 and the intercom 20 in the lobby, the information terminal 1 receives from the user a voice containing "open the door" as a control word. In this case, the voice recognition unit 33 determines that the control word "open the door" is included in the voice processed by the voice processing unit 31 .

The control processing unit 35 controls the unlocking action of the electronic lock 201 of the entrance door 200 for entering the room from the common entrance E1. For example, the control processing unit 35 controls the control device 40 so as to perform the unlocking operation using the electronic lock of the entrance door 200 entering the room from the common entrance E1.

Furthermore, the control processing unit 35 controls the unlocking of the electronic lock 201 of the entrance door 200 when the operation unit 4 accepts a specific operation from the user.

The delay processing unit 36 restricts the switching of the voice recognition function with an appropriate delay time according to the switching of the operation mode of the information terminal 1 . The delay processing unit 36 restricts the voice control function, for example, after 30 minutes have elapsed since the user switched the operation mode of the information terminal 1 from the home mode to the out-of-office mode. The user can set the delay time appropriately. When the operation mode of the information terminal 1 is switched after the delay time has elapsed, the delay processing unit 36 can also limit the sound control function at the same time as the operation mode is switched.

The display processing unit 37 performs processing for causing the display unit 6 to display an image captured by the intercom entrance device (the lobby intercom 20 and the entrance sub-unit 30 ) as a communication object.

The sending unit 38 outputs the audio-related audio data (audio information) acquired by the sound-receiving unit 202 to a device operated by the person on the call side. Specifically, the transmission unit 38 transmits the audio signal after noise suppression or removal by the audio processing unit 31 to the intercom entrance device (the lobby intercom 20, the entrance sub-unit) of the communication partner via the first communication unit 8 or the second communication unit 9 30). For example, when the information terminal 1 communicates with the lobby walkie-talkie 20 , the transmission unit 38 transmits the audio signal after noise suppression or removal by the sound processing unit 31 to the lobby walkie-talkie 20 via the first communication unit 8 .

(2-2) Intercom in the lobby As shown in FIG. 2 , the lobby walkie-talkie 20 includes a communication unit 21 , a control unit 22 , a communication unit 23 , a display unit 24 , an operation unit 25 , a memory unit 26 , an imaging unit 27 , and a sensor unit 28 .

As shown in FIG. 2 , the lobby walkie-talkie 20 includes, for example, a microcomputer having a processor and a memory. Then, when the processor executes the program stored in the memory, the microcomputer functions as the control unit 22 . The program executed by the processor is pre-recorded in the memory of the microcomputer here, but it can also be provided by being recorded on a non-transitory recording medium such as a memory card, or provided through a telecommunication line such as the Internet.

The communication unit 21 is a communication interface for communicating with the information terminal 1 (the first communication unit 8 of the information terminal 1). The communication unit 21 is connected to the control device 40 (the communication unit 41 thereof) via the first trunk line 61 . The communication unit 21 transmits audio signals, video signals, and the like to the information terminal 1 via the control device 40 . Furthermore, the communication unit 21 receives audio signals, control signals, and the like from the information terminal 1 via the control device 40 . Here, the communication signal from the lobby intercom 20 includes information (eg, address information, etc.) for specifying the information terminal 1 . Therefore, only the information terminal 1 to which the address information corresponding to the address information contained in the communication signal is assigned can receive the communication signal.

The control unit 22 is configured to control the communication unit 21 , the communication unit 23 , the imaging unit 27 , and the like.

The communication unit 23 includes a speaker and a microphone, and can communicate with the information terminal 1 .

The display unit 24 is, for example, a liquid crystal display. The display unit 24 is configured to display the image captured by the imaging unit 27 . Also, the display unit 24 is configured to display a message to a visitor or the like. The message is, for example, a message for urging a visitor or the like to speak. The display unit 24 displays a message such as "please speak". In this case, the same voice message may be output (announced) from the speaker of the communication unit 23 or a speaker provided separately from the speaker of the communication unit 23 . Moreover, the display part 24 and a speaker may be used together.

For example, when the operation mode of the information terminal 1 is the home mode, the switching unit 34 determines that the restriction of the voice control function is not performed. On the other hand, when the operation mode of the information terminal 1 is, for example, the outgoing mode or the crime prevention mode, the switching unit 34 determines that the restriction of the voice control function is performed.

When it is determined that the restriction of the voice control function is performed (“Yes” in step S12 ), the switching unit 34 restricts the voice control function (step S13 ). Specifically, the switching unit 34 switches the restriction of the sound control function from invalid to valid when the sound control function is invalid, or maintains the valid state when the sound control function is valid to limit the sound control function (step S13).

When it is determined that the restriction of the voice control function is not to be performed (“No” in step S12 ), the switching unit 34 determines whether or not the restriction of the voice control function needs to be released (step S14 ). When the switching unit 34 determines that it is necessary to release the restriction of the voice control function (“Yes” in step S14 ), the switching unit 34 performs the removal of the restriction of the voice control function (step S15 ), and ends the process. Specifically, the switching unit 34 switches the limitation of the sound control function from valid to invalid when the sound control function is valid, or maintains the invalid state to limit the sound control function when the sound control function is invalid . In addition, when there is no need to release the restriction of the voice control function (“No” in step S14 ), the process is directly terminated.

From the above, the walkie-talkie system 100 restricts the voice control function of the information terminal 1 .

Next, the operation of the walkie-talkie system 100 will be described with reference to FIG. 4 . The audio pickup unit 202 acquires audio (step S51). The voice recognition unit 33 determines whether or not the audio frequency processed by the voice processing unit 31 includes a trigger word that is a trigger to start the voice recognition processing (step S52). When the voice recognition unit 33 determines that the trigger word is not included in the voice processed by the voice processing unit 31 (NO in step S52 ), the process returns to step S51 . When the voice recognition unit 33 determines that a trigger word is included in the voice processed by the voice processing unit 31 (“Yes” in step S52 ), the voice recognition unit 33 performs voice recognition processing (step S53 ).

The voice recognition unit 33 judges whether or not the control keyword is included in the audio processed by the voice recognition processing (step S54). When the voice recognition unit 33 judges that the audio frequency processed by the voice recognition processing does not contain the control word (“No” in step S54 ), the processing returns to step S53 .

When the voice recognition unit 33 judges that the audio frequency processed by the voice recognition processing contains the control word (“Yes” in step S54 ), the control processing unit 35 judges whether the restriction of the voice control function is valid (step S55 ).

When the control processing unit 35 determines that the restriction of the voice control function is valid (“Yes” in step S55 ), the processing ends. When the control processing unit 35 determines that the restriction of the voice control function is not valid, that is, invalid (NO in step S55 ), the control processing unit 35 performs control processing based on the control word (step S56 ).

(4) Advantages As described above, the information terminal 1 is the information terminal 1 that operates as a terminal included in the walkie-talkie system 100 installed in the facility 70 , and includes the control unit 3 having a sound based on the sound received by the sound pickup unit 202 .

(5) Variation example Hereinafter, a modification will be described. In addition, the modification example demonstrated below can be combined suitably with the above-mentioned embodiment, and can be applied.

(5-1) Variation 1 In the embodiment, the restriction of the voice control function includes a configuration in which the control corresponding to the voice recognition result of the voice recognition unit 33 is disabled, but it is not limited to this configuration. The limitation of the voice control function may also include the invalidation of the voice recognition function. For example, in this modification, the voice recognition unit 33 has a flag related to processing. Specifically, the flag of the voice recognition unit 33 is limited to switch whether the voice recognition function is present or not. When the flag is "1", the voice recognition function of the voice recognition unit 33 is not limited. When the flag is "0", the voice recognition function of the voice recognition unit 33 is limited, and the limitation of the voice recognition function includes setting the voice recognition function to be invalid. That is, when the flag is "0", the voice recognition processing by the voice recognition unit 32 is not performed.

This modified example will be described using FIG. 5 .

The switching unit 34 acquires the operation mode of the information terminal 1 (step S21). The switching unit 34 determines whether or not to restrict the sound control function based on the acquired operation mode (step S22). When the switching unit 34 determines that the voice control function is restricted (“Yes” in step S22 ), the switching unit 34 sets the processing flag of the voice recognition unit 33 to “0” (step S24 ). When the switching unit 34 determines that the voice control function is not restricted (“No” in step S22 ), the switching unit 34 sets the processing flag of the voice recognition unit 33 to “1” (step S24 ).

According to the above, the limitation of the voice recognition function includes the invalidation of the voice control function. The invalidation of the voice control function not only includes the case where the result of the voice recognition processing is not used, but also the case where the voice recognition processing itself is not performed as in this modification.

(5-2) Variation 2 In Modification 2, the operation of the information terminal 1 includes a configuration in which the operation mode of the information terminal 1 is included, but it is not limited to this configuration. The actions of the information terminal 1 may also include receiving information from other devices in communication with the information terminal 1 . For example, other machines include hall walkie-talkies 20, entrance sub-machines 30, electronic locks 201, express cabinets, smart phones, human sensors, lighting fixtures, blinds, and power monitors.

When the information received from other equipment is information accompanying the user of the information terminal 1 leaving the facility 70, the sound control function is disabled. For example, it includes the case where the user's figure going out of the facility 70 is reflected on the lobby intercom 20 and the entrance handset 30 , and the case where the electronic lock 201 is unlocked and locked from the inside of the facility 70 . Also, for example, it includes the situation of setting the user's express cabinet, the situation that the human sensor in the lobby responds, the situation that the power consumption in the power monitor is reduced, and the like. The control unit 3 restricts the sound control function based on the situation that the user is estimated to be out of the facility 70 . In addition, the lobby intercom 20 and the entrance sub-unit 30 have the function of returning home notification. The user determines that he has returned home when the returning home notification is enabled. In accordance with the notification, the control unit 3 releases the restriction on the voice control function.

In addition, when the information received from other equipment is information accompanying the user's entry into the facility 70, the control unit 3 releases the restriction on the voice control function. For example, it includes the case where the user's figure entering the facility 70 is reflected on the intercom 20 and the entrance handset 30 in the lobby, and the case where the electronic lock 201 is unlocked and locked from the outside. Also, for example, it includes the case where the user's courier setting is canceled, the case where the human sensor in the lobby reacts from the outside to the inside, and the case where the power consumption in the power monitor increases. The control unit 3 releases the restriction on the voice control function based on the situation that the user is estimated to have entered the facility 70 .

(5-3) Variation 3 In Variation 3, the operation of the information terminal 1 includes a setting state set in accordance with an input from the user, and the control unit 3 restricts the voice control function based on the setting state, but is not limited to this structure. The operation of the information terminal 1 may include accepting an operation on the information terminal, and the control unit 3 may limit the sound control function when the information terminal 1 is not operated for a specific period. The control unit 3 restricts the sound control function when the information terminal 1 is not operated for a specific period, for example, 30 minutes. Specifically, when it is considered that there is no operation for 30 minutes, for example, the control unit 3 switches the switching unit 34 from valid to invalid, and restricts the control processing unit 35 . Therefore, the control unit 3 restricts the sound control function.

On the other hand, in the state where the voice control function is restricted, the control unit 3 releases the restriction on the voice control function if a specific recovery condition is satisfied. Here, the specific recovery conditions include, for example, receiving audio with a specific sound pressure or higher, calling from the lobby intercom 20, receiving a preset wake-up word, and operating the intercom device. Specifically, the control unit 3 switches the switching unit 34 from inactive to active by accepting the operation of the operation unit 4, accepting the input of the wake-up word, which is a control word, and the like by the sound pickup from the sound pickup unit 202 . Therefore, the restriction of the sound control function is lifted.

(5-4) Variation 4 The notification unit 11 may also notify the presence or absence of the restriction of the sound control function. Specifically, it demonstrates using FIG. 6. FIG.

The sound pickup unit 202 acquires sound (step S40). The voice recognition unit 33 determines whether the voice processed by the voice processing unit 31 contains a trigger word (step S41 ). When the trigger word is not included in the sound (NO in step S41 ), the process ends. When the trigger word is included in the voice (“Yes” in step S41 ), the voice recognition unit 33 determines whether or not the control character is included in the voice (step S42 ). When a trigger word or the like is included, the voice recognition result is forced to be used regardless of the setting content of the switching unit 34 . When the word for control is included (“Yes” in step S42 ), the control unit 3 determines whether or not there is a restriction on the voice control function (step S47 ). When the voice control function is not restricted (“Yes” in step S47 ), the notification unit 11 notifies that the voice control function is not restricted (step S50 ). When the voice control function is restricted (NO in step S47 ), the control unit 3 releases the control (step S48 ), and the notification unit 11 notifies that the voice control function is not restricted.

When the voice processed by the voice processing unit 31 does not contain the setting keyword (NO in step S42 ), the control unit 3 determines whether the voice control function is restricted (step S43 ). When the voice control function is restricted (“Yes” in step S43 ), the notification unit 11 notifies that the voice control function is restricted (step S46 ).

When the voice control function is not under restriction (NO in step S43), the control unit 3 restricts the voice control function (step S44), and the notification unit 11 notifies that the voice control function is restricted (step S45).

According to the above, the notification unit 11 can display and set a trigger word such as "I'm back" on the information terminal 1 and perform an operation in which the original voice recognition can work, and can prompt "Voice control function is limited", "Voice recognition is limited", "Voice recognition function is limited" etc.
