The camera 25 is an imaging device for imaging a visitor. The slave unit CPU 21 is a control unit for controlling the operation of the entrance slave unit 2. The slave unit I / F 26 constitutes a communication unit for communicating with the living room master unit 3 via the transmission line 10.

The living room master unit 3 includes a master unit CPU 31, a data storage unit 32 (an example of a storage unit) connected to the master unit CPU 31, a message storage unit 33, a response operation unit 34, a response refusal operation unit 35, a microphone 36, and a speaker 37. , Monitor 38, and master unit I / F39.

The master unit CPU 31 is a control unit for controlling the operation of the living room master unit 3, and serves as a recording unit 31A, a voice recognition unit 31B, a voice synthesis unit 31C, a living room master unit control unit 31D, and a message output control unit 31E. It has a function.

The data storage unit 32 stores the recorded data recorded by the recording unit 31A (for example, the voice of the visitor), the recorded data recorded by the camera 25 of the entrance slave unit 2 (for example, the video of the visitor), and the like. Is.

The message storage unit 33 is a storage unit that stores a message or the like on the resident side to be transmitted to the visitor. The message to be sent includes, for example, the first message for giving the visitor the name of the visitor, the second message generated by extracting the name of the visitor included in the recorded data, and the name of the visitor. A third message for giving the name again, a fourth message for notifying that the voice of the visitor can be recorded, and the like are included.

The first message is, for example, "(Pi) Yes. Who are you?" The "(pi)" before the message may or may not be present. The second message is, for example, a message such as "Mr. XX is here" following the ringing tone "Ping Pong". The third message is, for example, "I didn't know your name and couldn't call you. I'm sorry, please give me your name or company name again." The fourth message is, for example, "I can't respond right now. I'm sorry, please come back again. If you have any message, please follow the dial tone. Record for 45 seconds." Can be mentioned.

The response operation unit 34 is an operation unit operated by the resident to answer the call from the visitor. The response refusal operation unit 35 is an operation unit operated when the resident rejects the response to the call from the visitor. The response operation unit 34 and the response refusal operation unit 35 are composed of, for example, a touch button displayed on the screen of the monitor 38 or a push-type button provided on the housing of the living room master unit 3.

The microphone 36 and the speaker 37 form a communication unit for sending a message or the like on the resident side to the visitor and outputting a message or the like on the visitor side to the resident. The monitor 38 is a display device for displaying an image captured by the camera 25 of the entrance slave unit 2. The master unit I / F 29 constitutes a communication unit for communicating with the entrance slave unit 2 via the transmission line 10.

The recording unit 31A in the master unit CPU 31 records the voice of the visitor transmitted from the entrance slave unit 2.
The voice recognition unit 31B recognizes a specific word associated with the visitor name from the recorded data (for example, the voice of the visitor) recorded by the recording unit 31A. For example, it recognizes whether or not a specific word (such as "is" or "is") is included in the end of the visitor's voice. Further, when a specific word is recognized, the voice recognition unit 31B identifies and extracts the visitor name included in the recorded data. In addition, the voice recognition unit 31B recognizes whether or not there is a visitor's message in response to the message from the resident side.
The voice synthesis unit 31C uses the visitor name extracted by the voice recognition unit 31B to generate a second message to be transmitted to the visitor.

The living room master unit control unit 31D receives a ringing operation from the entrance slave unit 2 and controls the ringing tone and the reproduction of the recorded data. Further, the living room master unit control unit 31D starts recording voice by the recording unit 31A when the first message, the third message, and the fourth message are output. The time when the message is output may be, for example, the time when the output of the message is started or the time when the output of the message is finished. Further, the living room master unit control unit 31D sets a call response time during which the resident can perform a response operation on the response operation unit 34. The call response time can be adjusted in advance by the resident operating the living room master unit 3.

Further, the living room master unit control unit 31D stores the recorded data recorded by the camera 25 of the entrance slave unit 2 in the data storage unit 32. Further, the living room master unit control unit 31D causes the monitor 38 to display the recorded data stored in the storage unit 32. Further, the living room master unit control unit 31D deletes the recorded data and the recorded data from the data storage unit 32 when it is recognized that the visitor does not speak in response to the third message and the fourth message.

When the entrance slave unit 2 is called by a visitor, the message output control unit 31E causes the visitor to output a first message from the entrance slave unit 2. Further, when the message output control unit 31E recognizes that the recorded data contains a specific word associated with the visitor name, the message output control unit 31E rings a second message generated by extracting the visitor name. At the same time, the output is output from the entrance slave unit 2 and the living room master unit 3. On the other hand, when it is recognized that the specific word is not included in the recorded data, the message output control unit 31E outputs a third message for re-identifying the visitor name from the entrance slave unit 2. Further, the message output control unit 31E can record a message when the answer operation unit is not operated within the call response time or when the resident performs the response refusal operation by the response refusal operation unit. A fourth message for notifying the visitor is output from the entrance slave unit 2.

In this example, the message storage unit 33 and the message output control unit 31E are provided in the living room master unit 3, but may be provided in the entrance slave unit 2, for example.

Next, the operation of the intercom device 1 will be described with reference to FIGS. 2 and 3.
When the call button 22 of the entrance slave unit 2 is pressed by the visitor (step S101), the slave unit CPU 21 transmits a call signal from the slave unit I / F 26 to the living room master unit 3 via the transmission line 10. When the call button 22 of the entrance slave unit 2 is pressed, the camera 25 starts imaging the visitor (step S102), and the captured video signal of the visitor is transmitted from the slave unit communication I / F 26 to the transmission path. It is transmitted to the living room master unit 3 via 10.

When the living room master unit 3 receives the call signal, the message output control unit 31E of the master unit CPU 31 reads the first message from the message storage unit 33. At this stage, the living room master unit control unit 31D of the master unit CPU 31 does not yet make the ringing tone sound from the speaker 37. The message output control unit 31E transmits the first message read from the message storage unit 33 to the entrance slave unit 2 via the transmission line 10, and outputs the first message to the visitor from the speaker 24 of the entrance slave unit 2. (Step S103).

The first message is a message that gives the visitor a name as described above, and specifically, it is a voice guidance such as "(Pi) Yes. Who are you?". In this case, in order to inform the visitor that the call has been accepted, it is desirable to make an electronic sound such as (pip) or (pop) sound before the voice message. In addition, although it is easier for the voice message to output the actual human voice for natural communication, there is a possibility that the visitor mistakenly thinks that the resident has responded and tries to start the conversation as it is. Therefore, it is desirable that the first message is a voice message indicating that the response is made by a voice synthesized by a machine.

By outputting the first message from the speaker 24 of the entrance slave unit 2, the visitor can easily say his / her name (or company name) into the microphone 23 after the first message is completed. Become.

The living room master unit control unit 31D starts recording voice by the recording unit 31A, for example, when the output of the first message ends (step S104). The recorded recorded data is stored in the data storage unit 32.

Further, when the living room master unit 3 receives the video signal, the living room master unit control unit 31D causes the monitor 38 to display the video signal. The camera 25 of the entrance slave unit 2 starts recording the video of the visitor in synchronization with the start of audio recording by the recording unit 31A of the living room master unit 3, and the recorded recording data is the living room master unit. It is sent to 3. The living room master unit control unit 31D stores the received recorded data in the data storage unit 32.

The voice recognition unit 31B determines whether or not the recorded data includes the voice of the visitor (step S105). When it is determined that the recorded data contains the voice of the visitor (YES in step S105), the voice recognition unit 31B determines whether or not the voice of the visitor contains a specific word (YES in step S105). Step S106).

As mentioned above, "specific words" are "-desu", "-dayo", "-but", "I'm", "-called", and "-" that are included in the ending of the visitor's voice. I came to deliver it. " In this example, it is determined that the visitor's name is included in the visitor's voice by recognizing that these words are included in the ending of the voice. Specifically, the voice recognition unit 31B determines and extracts the word spoken immediately before the specific word such as "is" as the name of the visitor. If words such as "Hello" and "I'm sorry" are recognized among the words spoken immediately before, those words may be removed.

When it is determined in step S106 that a specific word is included (YES in step S106), the voice synthesis unit 31C stores the visitor's name extracted by the voice recognition unit 31B and the message storage unit 33. A second message is generated by synthesizing the second message lacking the name part (step S107 in FIG. 3).

The second message is a voice message such as "Ping pong, Mr. XX is here" as described above. The message output control unit 31E outputs the generated second message from the speaker 37 to the resident, and transmits the generated second message to the entrance slave unit 2 to output the generated second message from the speaker 24 of the entrance slave unit 2 to the visitor. (Step S108). In this case, it is desirable to output the second message not only from the living room master unit 3 but also from the entrance slave unit 2 so that the visitor can recognize that the call to the resident has been started.

On the other hand, in step S105, it is determined that the recorded data does not include the visitor's voice (NO in step S105), and in step S106, it is determined that the visitor's voice does not contain a specific word. If this is the case (NO in step S106), the living room master unit control unit 31D proceeds to step S109 shown in FIG. As a visitor's voice that does not contain a specific word, for example, "Please go to the front door" and so on.

In step S109, the living room master unit control unit 31D determines whether or not a predetermined predetermined time (for example, 45 seconds) has elapsed, and if it is determined that the predetermined time (for example, 45 seconds) has not elapsed (NO in step S109). ), The processing of step S105 and step S106 is repeated. On the other hand, when it is determined in step S109 that the predetermined time has elapsed (YES in step S109), the living room master unit control unit 31D records the voice by the recording unit 31A and the recording by the camera 25. Is stopped, and the process proceeds to step S110.

In step S110, the message output control unit 31E reads the third message from the message storage unit 33, transmits it to the entrance slave unit 2, and outputs the third message from the speaker 24 of the entrance slave unit 2 to the visitor. Let me. The third message is a message that re-names the visitor as described above. Specifically, "I didn't know your name and couldn't call you. I'm sorry, but please give me your name or company name again. It is a voice guidance such as "I will."

The living room master unit control unit 31D starts recording voice by the recording unit 31A, for example, when the output of the third message ends (step S111). The recorded recorded data is stored in the data storage unit 32. The camera 25 of the entrance slave unit 2 starts recording the video of the visitor in synchronization with the start of audio recording by the recording unit 31A, and the recorded recording data is transmitted to the living room master unit 3. The living room master unit control unit 31D stores the received recorded data in the data storage unit 32.

In step S112 and step S113, the living room master unit control unit 31D performs the same processing as in steps S105 and S106 described above, respectively, and determines whether or not the visitor voice contains a specific word. When it is determined that the visitor voice contains a specific word (YES in step S112 and YES in step S113), the room master unit control unit 31D proceeds to step S107 and step S108 to proceed to each of the above-mentioned steps. Perform processing. On the other hand, when it is determined that the specific word is not included (NO in step S112 or NO in step S113), the living room master unit control unit 31D proceeds to step S114 and proceeds to step S114 for a predetermined time set in advance. It is determined whether or not (for example, 45 seconds) has elapsed. Then, when it is determined that the predetermined time has not elapsed (NO in step S114), the living room master unit control unit 31D returns to step S110 and repeats each process. On the other hand, if it is determined that the predetermined time has elapsed (YES in step S114), it is determined that the visitor has left without speaking, and the living room master unit control unit 31D proceeds to step S125. In step S125, the living room master unit control unit 31D outputs a voice guidance such as "I did not know your name and could not call" from the speaker 24 of the entrance slave unit 2 until the middle of the third message. After that, the process is terminated without reporting the ringing tone from the speaker 37 of the living room master unit 3 even once.

After the output processing of the second message for calling the resident is performed in step S108, the living room master unit control unit 31D determines whether or not the resident has operated the response operation unit 34 in response to the second message. Determine (step S115). If it is determined that the resident has responded (YES in step S115), it is determined that a call has been made between the visitor and the resident, and the audio recording and the video recording are terminated (YES). Step S116), the process ends.

On the other hand, if it is determined that there is no response operation (NO in step S115), the living room master unit control unit 31D determines whether or not the resident has operated the response refusal operation unit 35 (step S117). If it is determined that there has been no response refusal operation by the resident, the living room master unit control unit 31D proceeds to step S118 and determines whether or not a predetermined predetermined time (for example, 45 seconds) has elapsed. To do. Then, when it is determined that the predetermined time has not elapsed (NO in step S118), the living room master unit control unit 31D returns to step S115 and repeats each process. On the other hand, when it is determined that the predetermined time has elapsed (YES in step S118), it is determined that there is no response from the resident to the second message, and the living room master unit control unit 31D determines. , The recording of the voice by the recording unit 31A and the recording by the camera 25 are stopped, and the process proceeds to step S119.

In step S119, the message output control unit 31E reads the fourth message from the message storage unit 33, transmits it to the entrance slave unit 2, and outputs the fourth message from the speaker 24 of the entrance slave unit 2 to the visitor. Let me. The fourth message is a message that informs the visitor that the voice can be recorded as described above. Specifically, "I cannot respond right now. I'm sorry, but please come again. If you have any message, please follow the dial tone. Record for 45 seconds. " The case where the fourth message is output after a predetermined time has passed includes, for example, the case where the resident is absent and cannot respond.

The living room master unit control unit 31D starts recording voice by the recording unit 31A, for example, when the output of the fourth message ends (step S120). The recorded recorded data is stored in the data storage unit 32. The camera 25 of the entrance slave unit 2 starts recording the video of the visitor in synchronization with the start of audio recording by the recording unit 31A, and the recorded recording data is transmitted to the living room master unit 3. The living room master unit control unit 31D stores the received recorded data in the data storage unit 32.

On the other hand, if it is determined in step S117 that the resident has rejected the response (YES in step S117), the room master unit control unit 31D proceeds to step S119 and step S120, and performs each of the above-described processes. Do. Examples of the case where the response is rejected and the fourth message is output include a case where the resident who hears the visitor's name, company name, etc. decides that it is a sales and refuses.

When a predetermined time (45 seconds for recording) has elapsed from the output of the fourth message (step S121), the room master unit control unit 31D proceeds to step S122 to record audio and video. finish. Subsequently, the voice recognition unit 31B determines whether or not there is a visitor's message for the fourth message (step S123). If it is determined that there is a visitor's message (YES in step S123), the process ends as it is. On the other hand, when it is determined that there is no visitor's message (NO in step S123), the room master unit control unit 31D processes the recorded data and the recorded data after erasing the recorded data from the data storage unit 32 (step S124). To finish.

The recorded data and the recorded data stored in the data storage unit 32 are reproduced by operating the reproduction button provided on the living room master unit 3. When the play button is pressed, the living room master unit control unit 31D reads the recorded data and the recorded data from the data storage unit 32, and outputs audio and video via the speaker 37 and the monitor 38. For example, a resident who has gone out can confirm the name, appearance, requirements, etc. of a visitor by playing back the recorded data and the recorded data after returning home. Residents can also identify visitors who have refused to respond.

In this example, voice recording is started every time the first, third, and fourth messages are output, but the present invention is not limited to this. For example, the voice recording may be started when the first message is output, and the recording may be continuously recorded thereafter without stopping the recording. Further, the video recording may be continuously recorded in the same manner.
Further, in this example, the data storage unit 32 stores a message or the like for the fourth message of the visitor whose response is rejected by the resident, but it may be deleted.

By the way, in the conventional intercom device, for example, when a ringing tone sounds, the resident often does not know who visited until he / she looks at the monitor of the living room master unit. Also, if the visitor is a stranger even if you look at the monitor of the master unit in the room, you cannot find out who the visitor is unless you answer the ringing tone. For this reason, it may respond to a person who does not want to deal with sales or the like. Also, for example, if there is no response from the resident to the call, the visitor is often silent and in front of the intercom. For this reason, even if the resident plays the recorded video and recorded audio after returning home, if the visitor in the absence is a person unknown to the resident, it is not possible to know what kind of business the visitor came from. .. Also, for example, when the resident is absent, the visitor cannot leave a message even if he / she wants to leave a message because he / she does not know whether or not the recording function of the intercom is present. Also, even if the visitor finds out that there is a recording function, he / she thinks that there may be a resident's response to the call, so he / she cannot leave a message at the first call and should make the call again. Is necessary and the burden on the visitor side is heavy.

On the other hand, according to the intercom device 1 of the present invention, when there is a calling operation, the visitor is guided to give his / her own name without requiring a special operation, and whether or not the visitor has given his / her name is voiced. Only when it is recognized and the name is given, the calling operation by the living room master unit 3 is performed. Therefore, since the resident can make the visitor's name sound in the living room without operating the living room master unit 3, the resident can easily determine whether or not a response to the visitor is necessary. Yes, security can be ensured. In addition, the visitor only waits for the resident's response after pressing the call button 22, for example, and the usability is not so different from that of the conventional general intercom device. There is no loss.

In addition, it is possible to determine whether or not the visitor has given his / her name by voice-recognizing the ending of the utterance of the visitor, and it is possible to extract the visitor's name from the utterance. Therefore, even the voice recognition unit 31B whose recognition performance is not so high can accurately extract the visitor name, so that the master CPU 31 can be realized by an inexpensive CPU.

Further, if there is no response from the visitor to the first message for giving the name of the visitor, the third message for giving the name of the visitor is output again. Therefore, even if the resident does not respond, the visitor can be provided with multiple opportunities to give his / her name, and security can be further ensured.

In addition, if the resident cannot or does not want to answer the visitor's call, the visitor's name and message can be recorded. For this reason, for example, a visitor can record and leave his / her name and message with a single call operation, and the operation burden and the like can be reduced. In addition, since the name and requirements can be left, even if the resident is absent and repeatedly visited, he / she will not be mistaken for a suspicious visitor. In addition, the resident can later check the recorded content to confirm the visitor's name and requirements.

In addition, if the visitor does not give his / her name to the third message, the entrance slave unit 2 outputs the output halfway through the third message, and the room master unit 3 does not make a call. Since it is possible to terminate the call, it is possible to suppress the confirmation of absence for the burglary and the call due to mischief. In addition, since voice recognition may be difficult due to dialects and the like, such processing may be selectable in the setting of the living room master unit 3.

In addition, since the voice and video of the visitor can be saved, the resident can confirm the name of the visitor by voice and the appearance of the visitor by video, which further enhances security. Secured. Further, when there is no utterance of the visitor in response to the fourth message, it is considered that the visitor has left without leaving a message, and the recorded data and the recorded data are deleted. Therefore, the memory usage of the data storage unit 32 Can be reduced.
