       FIG. 2  illustrates a block diagram of an electronic device for providing an artificial intelligence service during a phone call according to various embodiments of the present disclosure. In the following description, the electronic device  101  may include at least part of the electronic device  101  of  FIG. 1 . In the following description, a detailed description for an operation of a module overlapped with a construction of  FIG. 1  is omitted. 
     Referring to  FIG. 2 , the electronic device  101  may include the processor  120 , the input device  150 , the sound output device  155 , the communication module  190  and an audio mixer  230 . In the following description, at least some functions of modules (e.g., a voice recognition module  210 , a mode identification module  220  and the audio mixer  230 ) shown in dotted lines may be limited or omitted according to an embodiment as well. 
     According to an embodiment, the processor  120  may control the communication module  190  to provide a phone call service with a counterpart electronic device (e.g., the electronic device  104 ). For example, the processor  120  may control the communication module  190  to connect a communication link with the counterpart electronic device. The processor  120  may control the communication module  190  to transmit and/or receive a voice signal through the communication link with the counterpart electronic device. 
     According to an embodiment, an artificial intelligence control module  200  may activate an artificial intelligence agent (e.g., the server  108 ), based on a user input (e.g., a voice command, a physical button input and/or a soft button input) obtained through the input device  150  (e.g., a touch screen, a microphone, a physical button, etc.) during a phone call with the counterpart electronic device. As an example, in response to obtaining a voice command corresponding to the calling of the artificial intelligence agent during a phone call connection with the counterpart electronic device, the artificial intelligence control module  200  may control the communication module  190  to connect a communication link with the artificial intelligence agent. As an example, in response to an artificial intelligence service provision menu being activated during a phone call, the artificial intelligence control module  200  may maintain an active state. In response to the artificial intelligence service provision menu being inactivated during the phone call, the artificial intelligence control module  200  may be inactivated. 
     According to an embodiment, the voice recognition module  210  may obtain a voice command from audio data obtained through the input device  150 . For example, the voice recognition module  210  may obtain the voice command, through pre-processing (e.g., noise cancellation) of the audio data obtained through the input device  150 , text transformation (e.g., automatic speech recognition (ASR)), and natural language recognition (e.g., natural language understanding (NLU)). As an example, the voice recognition module  210  may obtain a voice command for an artificial intelligence service from audio data which is received before or after a voice command corresponding to the calling of the artificial intelligence agent (e.g., the server  108 ) through the input device  150  (e.g., a microphone). 
     According to an embodiment, the mode identification module  220  may identify an output mode of an artificial intelligence service, based on at least one of information (e.g., a voice command or a response of an agent) related with the artificial intelligence service or a mutual relation with a counterpart electronic device. For example, the mode identification module  220  may identify an output mode corresponding to at least one of the voice command for the artificial intelligence service or the response of the agent corresponding to the voice command, in a predefined table (e.g., database). As an example, the predefined table may include at least one of the voice command for setting in a non-public mode or the response of the agent. As an example, the predefined table may include an output mode for each voice command for providing the artificial intelligence service or the agent. For example, the mode identification module  220  may identify the output mode of the artificial intelligence service, based on intimacy levels of a user of the electronic device  101  and a user of the counterpart electronic device. As an example, the output mode corresponding to the intimacy level with the user of the counterpart electronic device may be identified through an intimacy level table. The intimacy level table may be refined based on a use history of the electronic device  101 . 
     According to an embodiment, the mode identification module  220  may identify an output mode of an artificial intelligence service, based on a service policy of the electronic device  101 . For example, in response to an output mode selected by a user and an output mode corresponding to information related with the artificial intelligence service being different from each other, the mode identification module  220  may identify the output mode of the artificial intelligence service, based on the service policy of the electronic device  101 . As an example, in response to a service policy which prioritizes personal information protection being set, the mode identification module  220  may set, as the output mode of the artificial intelligence service, an output mode whose security level is high among the output mode selected by the user and the output mode corresponding to the information related with the artificial intelligence service. For example, in response to the output mode corresponding to the mutual relation with the counterpart electronic device and the output mode corresponding to the information related with the artificial intelligence service being different from each other, the mode identification module  220  may identify the output mode of the artificial intelligence service, based on the service policy of the electronic device  101 . As an example, in response to a service policy which prioritizes information publication being set, the mode identification module  220  may set, as the output mode of the artificial intelligence service, an output mode whose security level is low among the output mode corresponding to the mutual relation with the counterpart electronic device and the output mode corresponding to the information related with the artificial intelligence service. As an example, the service policy of the electronic device  101  may be identified based on at least one of the kind of a voice command for the artificial intelligence service, a mutual relation with the counterpart electronic device, or a use history of the electronic device  101 . 
     According to an embodiment, the audio mixer  230  may selectively mix audio data corresponding to a phone call service and audio data corresponding to an artificial intelligence service, based on an output mode of an artificial intelligence service. For example, the audio mixer  230  may mix a voice signal received from a counterpart electronic device (e.g., the electronic device  104 ) through the communication module  190  and a response signal of the agent, as one audio signal, and output through the sound output device  155 . For example, in response to the output mode of the artificial intelligence service being a public mode, the audio mixer  230  may mix a voice signal received through the input device  150  and a response signal of the agent, as one audio signal, and control the communication module  190  to transmit to a counterpart electronic device. For example, in response to the output mode of the artificial intelligence service being a non-public mode, the audio mixer  230  may control the communication module  190  to transmit a user&#39;s voice signal received through the input device  150  to the counterpart electronic device. For example, in response to the output mode of the artificial intelligence service being a mosaic mode, the audio mixer  230  may mix a user&#39;s voice signal received through the input device  150  and at least part of a response signal of the agent, as one audio signal, and control the communication module  190  to transmit to the counterpart electronic device. As an example, the audio mixer  230  may replace a main phrase restricting transmission to the counterpart electronic device with another audio signal, or may batch process the same. As an example, the mosaic mode may include an output mode of restricting the publication of the main phrase among the response signal of the agent. 
     According to various embodiments of the present disclosure, the electronic device may provide an artificial intelligence service, based on a command by a different kind of input such as a text or gesture as well as a voice.

     According to an embodiment, in response to providing an artificial intelligence service during a phone call, the electronic device 1  300  may mix audio data for a phone call service and audio data for the artificial intelligence service. For example, the electronic device 1  300  may mix audio data provided from the electronic device 2  310  and audio data provided from the artificial intelligence agent  320 , as one audio data. As an example, the mixed audio data may be outputted through a speaker (e.g., the sound output device  155  of FIG.  1 ) of the electronic device 1  300 . For example, the electronic device 1  300  may selectively mix audio data received through a microphone (e.g., the input device  150  of  FIG. 1 ) and audio data provided from the artificial intelligence agent  320 , based on an output mode of the artificial intelligence service. As an example, in response to being a public mode, the electronic device 1  300  may mix audio data received through the microphone and audio data provided from the artificial intelligence agent  320 , as one audio data. The mixed audio data may be transmitted to the electronic device 2  310  through the base station  330 . As an example, in response to being a non-public mode, the electronic device 1  300  may restrict the mixing of the audio data received through the microphone and the audio data provided from the artificial intelligence agent  320 . In this case, the electronic device 1  300  may transmit the audio data received through the microphone, to the electronic device 2  310 . As an example, in response to being a mosaic mode, the electronic device 1  300  may mix at least part of the audio data provided from the artificial intelligence agent  320  and the audio data received through the microphone. The mixed audio data may be transmitted to the electronic device 2  310  through the base station  330 . The at least part of the audio data provided from the artificial intelligence agent  320  may include the remaining audio data excepting a main phrase among the audio data provided from the artificial intelligence agent  320 . 
     According to various embodiments of the present disclosure, in response to a communication channel for an artificial intelligence service of the electronic device 1  300  and a communication channel for a phone call with the electronic device 2  310  being separated from each other, the artificial intelligence agent  320  may mix audio data. For example, the artificial intelligence agent  320  may mix audio data for the phone call and audio data for the artificial intelligence service, and transmit to the electronic device 1  300  or the electronic device 2  310  through the base station  330 .

For example, in response to receiving a call from the counterpart electronic device (e.g., the electronic device  104  of  FIG. 1 ) through the communication module  190 , the processor  120  may control at least one of the sound output device  155 , the display device  160  or the haptic module  179  to output call reception notification information. In response to receiving an input for acceptance of call reception through the input device  150 , the processor  120  may control the communication module  190  to connect a call with the counterpart electronic device. For example, in response to a call connection event taking place based on a user input received through the input device  150 , the processor  120  may control the communication module  190  to transmit a call from the counterpart electronic device (e.g., the electronic device  104  of  FIG. 1 ) for call connection. In response to receiving a call acceptance signal through the communication module  190 , the processor  120  may provide a phone call service with the counterpart electronic device. 
     In operation  703 , the electronic device may identify whether a voice command for an artificial intelligence service is obtained during the phone call with the counterpart electronic device. For example, the processor  120  (e.g., the artificial intelligence control module  200  of  FIG. 2 ) may identify whether a voice command corresponding to the calling of an artificial intelligence agent (e.g., the server  108  of  FIG. 1 ) is obtained from audio data for the phone call with the counterpart electronic device. In response to obtaining the voice command corresponding to the calling of the artificial intelligence agent, the processor  120  (e.g., the voice recognition module  210  of  FIG. 2 ) may obtain a voice command for the artificial intelligence service from audio data received before or after the corresponding voice command. For example, the processor  120  (e.g., the artificial intelligence control module  200  of  FIG. 2 ) may identify whether an input of a physical button corresponding to the calling of the artificial intelligence agent (e.g., the server  108  of  FIG. 1 ) is obtained during the phone call with the counterpart electronic device. In response to obtaining the input of the physical button corresponding to the calling of the artificial intelligence agent, the processor  120  (e.g., the voice recognition module  210  of  FIG. 2 ) may obtain a voice command for the artificial intelligence service from received audio data from a time point of obtaining the input of the physical button. 
     In operation  705 , in response to obtaining the voice command for the artificial intelligence service during the phone call with the counterpart electronic device, the electronic device may identify an output mode of the artificial intelligence service, based on at least one of information related with the artificial intelligence service or a mutual relation with the counterpart electronic device. For example, the processor  120  (e.g., the mode identification module  220  of  FIG. 2 ) may identify whether a voice command matching with the voice command for the artificial intelligence service exists in a table corresponding to a non-public mode stored in the memory  130 . In response to obtaining the voice command matching with the voice command for the artificial intelligence service from the table corresponding to the non-public mode, the processor  120  may set the output mode of the artificial intelligence service as a non-public mode or a master mode. In response to the voice command matching with the voice command for the artificial intelligence service not existing in the table corresponding to the non-public mode, the processor  120  may set the output mode of the artificial intelligence service as a public mode or a mosaic mode. For example, the processor  120  (e.g., the mode identification module  220  of  FIG. 2 ) may obtain an output mode of the artificial intelligence service corresponding to an intimacy level between a user of the electronic device  101  and a user of the counterpart electronic device from an intimacy level table stored in the memory  130 . As an example, the intimacy level table may be refined based on a use history of the electronic device  101 . For example, in response to output modes corresponding to respective variables identifying the output mode of the artificial intelligence service being different from each other, the processor  120  may identify an output mode of the electronic device  101  for the artificial intelligence service, based on a service policy of the electronic device  101 . As an example, the variable identifying the output mode of the artificial intelligence service may include at least one of information related with the artificial intelligence service, a mutual relation with the counterpart electronic device or a user input for output mode selection. 
     In operation  707 , the electronic device may output a response of an agent corresponding to the voice command, based on the output mode of the electronic device for the artificial intelligence service. For example, in response to the output mode of the electronic device  101  being a public mode, the processor  120  may control the audio mixer  230  to mix a voice signal of a user received through the input device  150  and a response signal of the agent, as one audio signal. The audio mixer  230  may transmit the mixed audio signal to a counterpart electronic device through the communication module  190 . For example, in response to the output mode of the electronic device  101  being a mosaic mode, the processor  120  may control the audio mixer  230  to mix the response signal of the agent whose main phrase is masked and a voice signal of a user received through the input device  150 , as one audio signal. The audio mixer  230  may transmit the mixed audio signal to the counterpart electronic device through the communication module  190 . As an example, the main phrase may include at least one of bank information (e.g., an account number, a balance, etc.), a personal identification number, a password, or body information (e.g., a weight, a heart rate) of the user. For example, in response to the output mode of the electronic device  101  being a master mode or a non-public mode, the processor  120  may restrict the mixing of the response signal of the agent and the user&#39;s voice signal received through the input device  150 . As an example, in response to being the master mode, the processor  120  may control the communication module  190  to transmit the user&#39;s voice signal received through the input device  150 , to the counterpart electronic device. As an example, in response to being the non-public mode, the processor  120  may control the communication module  190  to transmit at least part of the user&#39;s voice signal received through the input device  150 , to the counterpart electronic device. The at least part of the user&#39;s voice signal received through the input device  150  may include the remaining voice signal excepting user&#39;s calling information corresponding to an artificial intelligence agent among the user&#39;s voice signal received through the input device  150 . 
     According to an embodiment, the electronic device may transform one response corresponding to a user&#39;s voice command to correspond to an output mode of the electronic device, and transmit to the counterpart electronic device. For example, the processor  120  may transform the response of the agent, based on an output mode of the electronic device  101  as in Table 2 below.

       FIG. 8  illustrates a flowchart for activating an artificial intelligence agent in an electronic device according to various embodiments of the present disclosure.  FIG. 9  illustrates a construction for activating the artificial intelligence agent by using a physical button according to various embodiments of the present disclosure.  FIG. 10  illustrates a construction for activating the artificial intelligence agent by using a software button according to various embodiments of the present disclosure. The following description is made for an operation for obtaining a voice command for an artificial intelligence service in operation  703  of  FIG. 7 . In the following description, the electronic device may include the whole or at least part of the electronic device  101  of  FIG. 1  or  FIG. 2 . 
     Referring to  FIG. 8 , in operation  801 , in response to connecting a phone call with a counterpart electronic device (e.g., operation  701  of  FIG. 7 ), the electronic device may identify whether an artificial intelligence service activation event occurs. For example, the processor  120  (e.g., the artificial intelligence control module  200  of  FIG. 2 ) may identify whether an input of a physical button of the electronic device  101  corresponding to an artificial intelligence service is received. As an example, in response to the electronic device  101  being a smart phone  900  as in  FIG. 9A , the processor  120  may identify whether an input of a physical button  902  corresponding to the artificial intelligence service in the smart phone  900  is received. As an example, in response to the electronic device  101  being a television  910  as in  FIG. 9B , the processor  120  may identify whether an input of a physical button  922  corresponding to the artificial intelligence service in a remote controller  920  corresponding to the television  910  is received. As an example, in response to the electronic device  101  being a speaker  930  as in  FIG. 9C , the processor  120  may identify whether an input of a physical button  932  corresponding to the artificial intelligence service in the speaker  930  is received. For example, the processor  120  may identify whether an input (e.g., a touch input) corresponding to a software button corresponding to the artificial intelligence service is received. As an example, in response to the electronic device  101  being a tablet  1000  as in  FIG. 10A , the processor  120  may identify whether a touch input corresponding to an icon  1012  corresponding to the artificial intelligence service among a plurality of icons  1010  displayed on a display device (e.g., the display device  160  of  FIG. 1 ) of the tablet  1000  is received. As an example, in response to the electronic device  101  being a refrigerator  1020  as in  FIG. 10B , the processor  120  may identify whether a touch input corresponding to an icon  1022  corresponding to the artificial intelligence service displayed on a display device of the refrigerator  1020  is received. As an example, in response to the electronic device  101  being a wearable device  1030  as in  FIG. 10C , the processor  120  may identify whether a selection input corresponding to an icon  1032  or physical button  1034  corresponding to the artificial intelligence service displayed on a display device of the wearable device  1030  is received. As an example, in response to the electronic device  101  being a notebook computer  1040  as in  FIG. 10D , the processor  120  may identify whether a selection input corresponding to an icon  1042  corresponding to the artificial intelligence service displayed on a display device of the notebook computer  1040  is received. For example, the processor  120  may identify whether a voice command corresponding to the calling of an artificial intelligence agent is obtained from audio data received through the input device  150 . 
     In response to the artificial intelligence service activation event not occurring, the electronic device may again identify whether the artificial intelligence service activation event occurs during a phone call with a counterpart electronic device. 
     In operation  803 , in response to the artificial intelligence service activation event occurring, the electronic device may activate an artificial intelligence service mode. For example, the processor  120  may control the communication module  190  to transmit an active signal to the artificial intelligence agent (e.g., the server  108  of  FIG. 1 ). 
     In operation  805 , the electronic device may identify whether a voice command corresponding to the artificial intelligence service is obtained. For example, the processor  120  may identify whether a voice command corresponding to the artificial intelligence service is obtained from audio data received through the input device  150  after the artificial intelligence service activation event occurs. As an example, the voice command corresponding to the artificial intelligence service may include a voice command matching in a table (e.g., a database) for the artificial intelligence service among at least one voice command obtained from the audio data received through the input device  150 . For example, in response to obtaining a voice command corresponding to the calling of the artificial intelligence agent, the processor  120  may identify whether the voice command corresponding to the artificial intelligence service is obtained from the audio data received through the input device  150  before or after the corresponding voice command. 
       FIG. 11  illustrates a flowchart for identifying an output mode in an electronic device according to various embodiments of the present disclosure. The following description is made for an operation for identifying an output mode of the electronic device  101  for an artificial intelligence service in operation  705  of  FIG. 7 . In the following description, the electronic device may include the whole or at least part of the electronic device  101  of  FIG. 1  or  FIG. 2 . 
     Referring to  FIG. 11 , in operation  1101 , in response to obtaining a voice command for an artificial intelligence service, the electronic device may identify an output mode corresponding to each variable for identifying an output mode of the artificial intelligence service. For example, the processor  120  (e.g., the mode identification module  220  of  FIG. 2 ) may identify at least one of an output mode corresponding to information (e.g., a voice command and/or a response of an agent) related with the artificial intelligence service, an output mode corresponding to a mutual relation with a counterpart electronic device or an output mode selected by a user input. As an example, in response to receiving a voice command such as “just a moment”, “wait a moment”, “I will ask and come back”, “I will ask an agent and inform you”, “I will talk with an agent alone and inform you” or the like, the processor  120  may set the output mode of the electronic device  101  as a non-public mode. As an example, in response to receiving a voice command such as “let us ask an agent”, etc., the processor  120  may set the output mode of the electronic device  101  as a public mode. 
     In operation  1103 , the electronic device may identify whether output modes corresponding to respective variables for identifying output modes of the artificial intelligence service are identical with each other. For example, the processor  120  (e.g., the mode identification module  220  of  FIG. 2 ) may identify whether the output mode corresponding to the information related with the artificial intelligence service and the output mode selected by the user input are identical with each other. For example, the processor  120  may identify whether the output mode corresponding to the information related with the artificial intelligence service and the output mode corresponding to the mutual relation with the counterpart electronic device are identical with each other. 
     In operation  1105 , in response to the output modes corresponding to the respective variables for identifying the output modes of the artificial intelligence service being different from each other, the electronic device may identify a service policy of the electronic device. For example, the processor  120  (e.g., the mode identification module  220  of  FIG. 2 ) may identify a service policy corresponding to at least one of the kind of a voice command for the artificial intelligence service or the mutual relation with the counterpart electronic device. As an example, in response to an intimacy level with the counterpart electronic device being equal to or being greater than a reference value, the processor  120  may set information sharing as the service policy of the electronic device  101 . As an example, in response to the intimacy level with the counterpart electronic device being less than the reference value, the processor  120  may set personal information protection as the service policy of the electronic device  101 . As an example, the intimacy level with the counterpart electronic device may be set based on at least one of the storing or non-storing of a phone number (e.g., identification information) of the counterpart electronic device in an address book of the electronic device  101 , the setting or non-setting of a favorite of the phone number of the counterpart electronic device, a phone call recursion, a message transmission and/or reception recursion, a phone call time point, a message transmission and/or reception time point, a phone call time, or relation setting information (e.g., a friend, a family, etc.) with a user of the counterpart electronic device. 
     In operation  1107 , the electronic device may identify the output mode of the electronic device for the artificial intelligence service, based on the service policy of the electronic device. For example, in response to the personal information protection being the service policy of the electronic device  101 , the processor  120  (e.g., the mode identification module  220  of  FIG. 2 ) may set an output mode whose security level is highest among the output modes corresponding to the respective variables for identifying the output mode of the artificial intelligence service, as the output mode of the electronic device  101  for the artificial intelligence service. For example, in response to information publication being the service policy of the electronic device  101 , the processor  120  may set an output mode whose security level is lowest among the output modes corresponding to the respective variables for identifying the output modes of the artificial intelligence service, as the output mode of the electronic device  101  for the artificial intelligence service. 
     In operation  1109 , in response to the output modes corresponding to the respective variables for identifying the output modes of the artificial intelligence service being identical with each other, the electronic device may set the output mode corresponding to the variable for identifying the output mode of the artificial intelligence service, as the output mode of the electronic device  101  for the artificial intelligence service. 
       FIG. 12  illustrates a flowchart for identifying an output mode, based on a service policy in an electronic device according to various embodiments of the present disclosure. The following description is made for an operation for identifying an output mode of the electronic device  101  for an artificial intelligence service in operation  705  of  FIG. 7 . In the following description, the electronic device may include the whole or at least part of the electronic device  101  of  FIG. 1  or  FIG. 2 . 
     Referring to  FIG. 12 , in operation  1201 , in response to obtaining a voice command for an artificial intelligence service (e.g., operation  703  of  FIG. 7 ), the electronic device may identify whether a manual input for selecting an output mode of the artificial intelligence service is obtained. For example, the processor  120  (e.g., the mode identification module  220  of  FIG. 2 ) may identify whether an input of a physical button for selecting the output mode of the artificial intelligence service or a selection input of an icon is obtained. 
     In operation  1203 , in response to the manual input for selecting the output mode of the artificial intelligence service being obtained, the electronic device may identify an output mode corresponding to the manual input. For example, the processor  120  (e.g., the mode identification module  220  of  FIG. 2 ) may identify the output mode corresponding to the manual input, based on a scheme of input of a physical button corresponding to the artificial intelligence service. As an example, in response to the input of the physical button being obtained once, the processor  120  may identify that an output mode of the electronic device  101  for the artificial intelligence service is a mosaic mode. As an example, in response to the input of the physical button being obtained continuously twice, the processor  120  may identify that the output mode of the electronic device  101  for the artificial intelligence service is a master mode. As an example, in response to the input of the physical button being maintained for a predetermined time, the processor  120  may identify that the output mode of the electronic device  101  for the artificial intelligence service is a non-public mode. 
     In operation  1205 , the electronic device may identify an output mode corresponding to information related with the artificial intelligence service. For example, the processor  120  (e.g., the mode identification module  220  of  FIG. 2 ) may identify the output mode corresponding to the information related with the artificial intelligence service, based on a security level of personal information included in at least one of a voice command corresponding to the artificial intelligence service or a response of an agent. As an example, in response to the personal information not being included in the voice command corresponding to the artificial intelligence service or the response of the agent, the processor  120  may set the output mode corresponding to the information related with the artificial intelligence service, as a public mode. As an example, in response to the voice command corresponding to the artificial intelligence service needing the personal information, the processor  120  may set the output mode corresponding to the information related with the artificial intelligence service, as any one of a mosaic mode, a master mode or a non-public mode, based on a security level of the personal information that is needed by the voice command. As an example, the response of the agent may include a response of the agent which is expected based on the kind of the voice command. 
     In operation  1207 , the electronic device may identify whether the output mode corresponding to the manual input and the output mode corresponding to the information related with the artificial intelligence service being identical with each other. 
     In response to the output mode corresponding to the manual input and the output mode corresponding to the information related with the artificial intelligence service being identical with each other, the electronic device may set the corresponding output mode as the output mode of the electronic device for the artificial intelligence service. 
     In operation  1209 , in response to the output mode corresponding to the manual input and the output mode corresponding to the information related with the artificial intelligence service being different from each other, the electronic device may identify a service policy of the electronic device. For example, the processor  120  (e.g., the mode identification module  220  of  FIG. 2 ) may set the service policy, based on at least one of the kind of a voice command for the artificial intelligence service, a mutual relation with a counterpart electronic device or a use history of the electronic device  101 . For example, the service policy of the electronic device  101  may be selected based on a user input. As an example, the use history of the electronic device  101  may include at least one of an information publication object or information publication history of the electronic device  101 . 
     In operation  1211 , the electronic device may identify the output mode of the electronic device for the artificial intelligence service, based on the service policy of the electronic device. For example, the processor  120  (e.g., the mode identification module  220  of  FIG. 2 ) may select any one output mode among the output mode corresponding to the manual input and the output mode corresponding to the information related with the artificial intelligence service, as the output mode of the electronic device  101  for the artificial intelligence service, based on the service policy of the electronic device. As an example, in response to the service policy of the electronic device  101  being personal information protection, the processor  120  may select an output mode whose security level is high. As an example, in response to the service policy of the electronic device  101  being a user selection priority, the processor  120  may select the output mode corresponding to the manual input. 
     In operation  1213 , in response to the manual input for selecting the output mode of the artificial intelligence service not being obtained, the electronic device may identify an output mode corresponding to the mutual relation with the busy counterpart electronic device. For example, the processor  120  (e.g., the mode identification module  220  of  FIG. 2 ) may identify the output mode corresponding to the mutual relation with the counterpart electronic device, based on an intimacy level with a user of the busy counterpart electronic device (e.g., the electronic device  104  of  FIG. 1 ). As an example, the intimacy level may be set based on at least one of the storing or non-storing of a phone number of the counterpart electronic device, the setting or non-setting of a favorite of the phone number of the counterpart electronic device, a phone call recursion, a message transmission and/or reception recursion, a phone call time point, a message transmission and/or reception time point, a phone call time, or relation setting information with the user of the counterpart electronic device. The relation setting information may include relation information with a user of the electronic device  101  and the user of the counterpart electronic device, stored in the memory  130 . 
     In operation  1215 , the electronic device may identify the output mode corresponding to the information related with the artificial intelligence service. For example, the processor  120  (e.g., the mode identification module  220  of  FIG. 2 ) may identify the output mode corresponding to the information related with the artificial intelligence service, based on a security level of personal information needed by the voice command corresponding to the artificial intelligence service. For example, in response to the voice command not needing a response of an agent like “Turn on TV”, the processor  120  may set a public mode as the output mode. For example, in response to storing the personal information like “I will take a voice memo”, the processor  120  may set a non-public mode as the output mode. 
     In operation  1217 , the electronic device may identify whether the output mode corresponding to the mutual relation with the counterpart electronic device and the output mode corresponding to the information related with the artificial intelligence service are identical with each other. 
     In response to the output mode corresponding to the mutual relation with the counterpart electronic device and the output mode corresponding to the information related with the artificial intelligence service being identical with each other, the electronic device may set the corresponding output mode as the output mode of the electronic device for the artificial intelligence service. 
     In operation  1209 , in response to the output mode corresponding to the mutual relation with the counterpart electronic device and the output mode corresponding to the information related with the artificial intelligence service being different from each other, the electronic device may identify the service policy of the electronic device. 
     In operation  1211 , the electronic device may identify the output mode of the electronic device for the artificial intelligence service, based on the service policy of the electronic device. For example, the processor  120  (e.g., the mode identification module  220  of  FIG. 2 ) may select any one output mode among the output mode corresponding to the mutual relation with the counterpart electronic device and the output mode corresponding to the information related with the artificial intelligence service, as the output mode of the electronic device  101  for the artificial intelligence service, based on the service policy of the electronic device. As an example, in response to the service policy of the electronic device  101  being information publication, the processor  120  may select an output mode whose security level is low. 
       FIG. 13  illustrates a flowchart for outputting a response of an agent, based on an output mode in an electronic device according to various embodiments of the present disclosure. The following description is made for an operation for outputting the response of the agent, based on the output mode of the electronic device for an artificial intelligence service in operation  707  of  FIG. 7 . In the following description, the electronic device may include the whole or at least part of the electronic device  101  of  FIG. 1  or  FIG. 2 . 
     Referring to  FIG. 13 , in operation  1301 , in response to identifying an output mode of an electronic device for an artificial intelligence service (e.g., operation  705  of  FIG. 7 ), the electronic device may identify whether the output mode of the electronic device is a public mode. 
     In operation  1303 , in response to the output mode of the electronic device for the artificial intelligence service being the public mode, the electronic device may mix a phone call voice and a response of an artificial intelligence agent, as one audio signal. For example, in response to the output mode of the electronic device for the artificial intelligence service being the public mode, the processor  120  may control the audio mixer  230  to mix the response of the artificial intelligence agent and a voice signal received from a busy counterpart electronic device (e.g., the electronic device  104  of  FIG. 1 ), as one audio signal. For example, in response to the output mode of the electronic device for the artificial intelligence service being the public mode, the processor  120  may control the audio mixer  230  to mix the response of the artificial intelligence agent and an audio signal received through the input device  150 , as one audio signal. 
     In operation  1305 , the electronic device may output the mixed audio signal through a sound output device and a communication module. For example, the processor  120  may control the sound output device  155  (e.g., a speaker) to output the audio signal mixed through the audio mixer  230 . For example, the processor  120  may control the communication module  190  to transmit the audio signal mixed through the audio mixer  230 , to a counterpart electronic device with which a phone call has been connected. 
     In operation  1307 , in response to the output mode of the electronic device for the artificial intelligence service being a non-public mode, the electronic device may identify whether it outputs a voice received from the busy counterpart electronic device. 
     In operation  1309 , in response to outputting an audio signal received from the busy counterpart electronic device, the electronic device may mix the audio signal received from the counterpart electronic device and a response signal of the artificial intelligence agent, as one audio signal. For example, irrespective of the output mode of the electronic device for the artificial intelligence service, the processor  120  may control the audio mixer  230  to mix the response of the artificial intelligence agent and a voice signal received from the busy counterpart electronic device (e.g., the electronic device  104  of  FIG. 1 ), as one audio signal. 
     In operation  1311 , the electronic device may output the mixed audio signal through the sound output device. For example, the processor  120  may control the sound output device  155  (e.g., the speaker) to output the audio signal mixed through the audio mixer  230 . 
     In operation  1313 , in response to outputting an audio signal to the busy counterpart electronic device, the electronic device may output, through the communication module, at least part of the audio signal received through the input device. For example, in response to the output mode of the electronic device for the artificial intelligence service being the non-public mode, the processor  120  may identify that it does not transmit the response of the agent to the busy counterpart electronic device. Accordingly to this, the processor  120  may control the communication module  190  to transmit at least part of the audio signal received through the input device  150  to the counterpart electronic device with which a phone call has been connected. As an example, the processor  120  may control the communication module  190  to transmit the remaining audio signal excepting at least partial audio signal related with the artificial intelligence service from the audio signal received through the input device  150 . The at least partial audio signal related with the artificial intelligence service may include an audio signal that is received after an artificial intelligence service activation event takes place. 
     According to an embodiment, in response to the output mode of the electronic device for the artificial intelligence service being the public mode, the electronic device may identify whether personal information is included in the response of the agent. In response to the personal information being included in the response of the agent, the electronic device may identify the publication or non-publication of the personal information, based on a service policy of the electronic device. For example, in response to the service policy being set as personal information protection, the electronic device may identify that it does not open the personal information included in the response of the agent, to the public. In this case, the electronic device may batch process the personal information included in the response of the agent or replace the same with a separate sound source (e.g., a background music or beef sound). For example, in response to the service policy being set as information publication, the electronic device may identify that it opens the personal information included in the response of the agent, to the public. 
       FIG. 14  illustrates a flowchart for outputting a response of an agent by using an external output device in an electronic device according to various embodiments of the present disclosure. The following description is made for an operation of outputting the response of the agent, based on an output mode of the electronic device for an artificial intelligence service in operation  707  of  FIG. 7 . In the following description, the electronic device may include the whole or at least part of the electronic device  101  of  FIG. 1  or  FIG. 2 . 
     Referring to  FIG. 14 , in operation  1401 , in response to identifying an output mode of the electronic device for an artificial intelligence service (e.g., operation  705  of  FIG. 7 ), the electronic device may identify whether an external output device capable of being operatively coupled with the electronic device exists. For example, the processor  120  may identify whether the external output device whose communication is connected with the electronic device  101  exists. For example, the processor  120  may control the communication module  190  to transmit a control signal (e.g., a beacon message) for identifying whether the external output device adjacent to the electronic device  101  exists. The processor  120  may identify whether the external output device capable of being coupled with the electronic device  101  exists, based on a response signal responsive to the control signal. As an example, the external output device may include an external speaker device. 
     In operation  1403 , in response to the external output device capable of being operatively coupled with the electronic device not existing, the electronic device may mix a phone call voice signal and a response signal of an artificial intelligence agent, as one audio signal. For example, irrespective of an output mode of the electronic device  101  for an artificial intelligence service, the processor  120  may control the audio mixer  230  to mix the response signal of the artificial intelligence agent and an audio signal received from a busy counterpart electronic device (e.g., the electronic device  104  of  FIG. 1 ), as one audio signal. 
     In operation  1405 , the electronic device may output the mixed audio signal through the sound output device. For example, the audio signal mixed through the audio mixer  230  may be outputted through the sound output device  155  (e.g., the speaker). 
     In operation  1407 , in response to the external output device capable of being operatively coupled with the electronic device existing, the electronic device may identify whether it outputs an audio signal received from the busy counterpart electronic device. 
     In operation  1409 , in response to outputting the audio signal received from the busy counterpart electronic device, the electronic device may output the audio signal received from the counterpart electronic device through a sound output device. For example, the processor  120  may control the sound output device  155  (e.g., the speaker) to output the audio signal received from the counterpart electronic device through the communication module  190 . 
     In operation  1411 , in response to outputting a response signal of the agent, the electronic device may transmit the response signal of the agent to the external output device. For example, the processor  120  may control the communication module  190  to transmit, to the external output device, audio data corresponding to a voice command received from the artificial intelligence agent (e.g., the server  108  of  FIG. 1 ). As an example, the external output device may output the audio data provided from the electronic device. 
     According to an embodiment, in response to a plurality of external output devices existing, the electronic device may select an external output device for outputting a response signal of an artificial intelligence agent, based on a distance with the electronic device. For example, the processor  120  may select at least one external output device whose distance with the electronic device  101  is most adjacent among the plurality of external output devices capable of being operatively coupled with the electronic device  102 . Additionally, the processor  120  may select the external output device for outputting the response signal of the artificial intelligence agent, based on an output state of the external output device. As an example, the processor  120  may identify whether an external output device not outputting an audio signal among the plurality of external output devices capable of being operatively coupled with the electronic device  102  exists. The processor  120  may select at least one external output device whose distance with the electronic device  101  is most adjacent among at least one external output device not outputting an audio signal. 
     According to an embodiment, in response to including a plurality of microphones, the electronic device may receive an audio signal for an artificial intelligence service by using a microphone different from a microphone used for a phone call. 
     According to an embodiment, in response to including a plurality of speakers, the electronic device may output a response signal of an agent for an artificial intelligence service by using a speaker different from a speaker outputting an audio signal for a phone call. 
     According to various embodiments of the present disclosure, in response to the external output device capable of being operatively coupled with the electronic device including a display device, the electronic device may output graphic data corresponding to an artificial intelligence service through the display device of the external output device. For example, the processor  120  may control the communication module  190  to transmit, to the external output device, graphic data corresponding to a voice command received from the artificial intelligence agent (e.g., the server  108  of  FIG. 1 ). The external output device may display the graphic data received from the electronic device through the display device.
