Details regarding operation  310  of  FIG. 3  may be applied to operation  510 . 
     In operation  520 , the at least one processor  120  of the electronic device  101  may identify whether the sound data is data related to the sound reproduced by an electronic device other than the electronic device  101 . According to various embodiments of the disclosure, the at least one processor  120  may convert the sound data into a log-mel signal and may extract a sound feature vector and an ambient noise feature vector based on the converted log-mel signal. The at least one processor  120  may identify whether the sound data is data related to the sound reproduced by the other electronic device or data related to a noise source actually existing, based on the log-mel signal, sound feature vector, and ambient noise feature vector. According to various embodiments of the disclosure, the at least one processor  120  may analyze the frequency band of the sound data and may identify that the sound data is data related to the sound reproduced by the other electronic device based on the absence of a component of a specific frequency band. 
     When it is determined in operation  530  that the sound data is data related to the sound reproduced by an electronic device other than the electronic device  101 , the at least one processor  120  may repeat operation  510  through operation  530  until sound data related to an actually existing noise source is identified. In other words, in determining the surrounding environment, the at least one processor  120  may not utilize the sound data related to the sound reproduced by the other electronic device. 
     When it is determined in operation  530  that the sound data is not data related to the sound reproduced by an electronic device other than the electronic device  101 , the at least one processor  120  may perform operation  540 . In operation  540 , the at least one processor  120  may obtain sensor data through at least one sensor (e.g., the sensor module  176 ). Details regarding operation  320  of  FIG. 3  may be equally applied to operation  540 . 
     In operation  550 , the at least one processor  120  may identify whether the surrounding environment matches one of a plurality of preset contexts based on the sound data and the sensor data. Details regarding operation  330  of  FIG. 3  may be equally applied to operation  550 . 
     In operation  560 , the at least one processor  120  may identify the state of the display (e.g., the display module  160 ) and whether the wearable electronic device  200  is outputting sound. Details regarding operation  340  of  FIG. 3  may be equally applied to operation  560 . 
     In operation  570 , the at least one processor  120  may perform at least one of transmitting a signal for controlling the wearable electronic device  200  through the communication circuit  190  to the wearable electronic device  200  or displaying a notification on the display  160  based on the matching context identified in operation  550  and the state of the display  160  and whether the wearable electronic device  200  is outputting sound, identified in operation  560 . Details regarding operation  350  of  FIG. 3  may be equally applied to operation  570 . 
     Although  FIG. 5  illustrates that the at least one processor  120  identifies whether the sound data is sound data related to the sound reproduced by another electronic device, according to various embodiments of the disclosure, it may be identified by the processor  240  of the wearable electronic device  200  whether the sound data is sound data related to the sound reproduced by the other electronic device. In this case, the wearable electronic device  200  may transmit information indicating whether the sound data is sound data related to the sound reproduced by the other electronic device to the electronic device  101 . According to various embodiments of the disclosure, the wearable electronic device  200  does not transmit the sound data related to the sound reproduced by the other electronic device to the electronic device  101  and transmits only sound data related to the actually existing noise source to the electronic device  101 . 
     According to various embodiments of the disclosure, when determining the surrounding environment, the electronic device  101  may consider only sound data related to the actually existing noise source while disregarding the sound data related to the sound reproduced by the other electronic device. Since the noise generated by content being reproduced by the other electronic device does not represent the surrounding environment of the electronic device  101 , the electronic device  101  may disregard the sound data related to the sound reproduced by the other electronic device, thereby accurately determining the surrounding environment.

     Like in operation  340 , identifying whether sound is being output through the sound output device  720  of the wearable electronic device  700  may mean identifying whether sound to be recognized by the user, like a sound corresponding to music or video, is being output. 
     In operation  850 , the at least one processor  740  may perform at least one of controlling the sound output device  720  or transmitting, to the external electronic device, a signal to display a notification on the display  160  of the external electronic device  101 .

     In operation  920 , the at least one processor  740  may identify whether the surrounding environment matches one of a plurality of preset contexts based on the sound data. Details regarding operation  420  of  FIG. 4  may be applied to operation  920 .

However, displaying on the display  160  regarding operation  440  may be replaced by transmitting, to the external electronic device  101 , a signal to allow the external electronic device  101  to display on the display  160  in operation  940 . Transmitting, to the wearable electronic device  200 , a control signal to allow the wearable electronic device  200  to perform a specific operation in operation  440  may be replaced by controlling the sound output device  720  to allow the at least one processor  740  to perform a specific operation in operation  940 . 
       FIG. 10  illustrates operations performed in a wearable electronic device according to an embodiment of the disclosure. 
     Referring to  FIG. 10 , in operation  1010 , at least one processor (e.g., the processor  740 ) of a wearable electronic device (e.g., the wearable electronic device  700 ) may obtain sound data regarding the surrounding environment through the sound input device  710 . 
     In operation  1020 , the at least one processor  740  may identify whether the sound data is data related to the sound reproduced by an electronic device other than the wearable electronic device  700 . Details regarding operation  520  of  FIG. 5  may be applied to operation  1020 . Operation  520  differs from operation  1020  in that operation  520  is performed by at least one processor  120  of the electronic device  101 , and operation  1020  is performed by at least one processor  740  of the wearable electronic device  700 . 
     When it is determined in operation  1030  that the sound data is data related to the sound reproduced by an electronic device other than the wearable electronic device  700 , the at least one processor  740  may repeat operation  1010  through operation  1030  until sound data related to an actually existing noise source is identified. In other words, in determining the surrounding environment, the at least one processor  740  may not utilize the sound data related to the sound reproduced by the other electronic device. 
     When it is determined in operation  1030  that the sound data is not data related to the sound reproduced by an electronic device other than the wearable electronic device  700 , the at least one processor  740  may perform operation  1040 .

     In operation  1060 , the at least one processor  740  determines the state of the display (e.g., the display module  160 ) of an external electronic device (e.g., the electronic device  101 ) and whether sound is being output through the sound output device  720  of the wearable electronic device  700 . Details regarding operation  840  of  FIG. 8  may be applied to operation  1060 . 
     In operation  1070 , the at least one processor  740  may perform at least one of controlling the sound output device  720  or transmitting, to the external electronic device, a signal to display a notification on the display  160  of the external electronic device  101 .

     According to various embodiments of the disclosure, when determining the surrounding environment, the wearable electronic device  700  may consider only sound data related to the actually existing noise source while disregarding the sound data related to the sound reproduced by the other electronic device than the wearable electronic device  700 . Since the noise generated by content being reproduced by the other electronic device does not represent the surrounding environment of the wearable electronic device  700 , the wearable electronic device  700  may disregard the sound data related to the sound reproduced by the other electronic device, thereby accurately determining the surrounding environment. 
       FIG. 11  illustrates a front view and a rear view of a first wireless audio device that may be included in a wearable electronic device according to an embodiment of the disclosure. 
     Referring to  FIG. 11 , a structure of a first wireless audio device  1100  that may be included in the wearable electronic device  200  is described with reference to  FIG. 11 . For convenience of description, a duplicate description is omitted, but the wearable electronic device  200  may further include a second wireless audio device (not shown) having the same or similar structure to the first wireless audio device  1100 . 
     Reference numeral  1101  denotes a front view of the first wireless audio device  1100 . The first wireless audio device  1100  may include a housing  1110 . The housing  1110  may form at least a portion of the exterior of the first wireless audio device  1100 . The housing  1110  may include a button  1113  and a plurality of microphones  1181   a  and  1181   b  disposed on a first surface (e.g., the surface facing the outside when worn). The button  1113  may be configured to receive a user input (e.g., a touch input or a push input). The first microphone  1181   a  and the second microphone  1181   b  may be included in the audio reception circuit  1181  of  FIG. 3 . The first microphone  1181   a  and the second microphone  1181   b  may be arranged to detect sound in a direction toward the outside of the user when the first wireless audio device  1100  is worn. The first microphone  1181   a  and the second microphone  1181   b  may be referred to as external microphones. The first microphone  1181   a  and the second microphone  1181   b  may detect sound outside the housing  1110 . For example, the first microphone  1181   a  and the second microphone  1181   b  may detect sound generated from the surroundings of the first wireless audio device  1100 . The sound of the surrounding environment detected by the first wireless audio device  1100  may be output by the speaker  1170 . In an embodiment of the disclosure, the first microphone  1181   a  and the second microphone  1181   b  may be sound-pickup microphones for a noise canceling function (e.g., active noise cancellation (ANC)) of the first wireless audio device  1100 . Further, the first microphone  1181   a  and the second microphone  1181   b  may be sound pickup microphones for the function of hearing ambient sound (e.g., a transparency function or an ambient aware function) of the first wireless audio device  1100 . For example, the first microphone  1181   a  and the second microphone  1181   b  may include various types of microphones including electronic condenser microphones (ECMs) and micro electro mechanical system (MEMS) microphones. A wing tip  1111  may be coupled to the circumference of the housing  1110 . The wing tip  1111  may be formed of an elastic material. The wing tip  1111  may be detached from the housing  1110  or attached to the housing  1110 . The wingtip  1111  may enhance wearability of the first wireless audio device  1100 . 
     Reference numeral  1102  denotes a rear view of the first wireless audio device  1100 . The housing  1110  may include a first electrode  1114 , a second electrode  1115 , a proximity sensor  1150 , a third microphone  1181   c , and a speaker  1170  disposed on a second surface (e.g., the surface facing the user when worn). The speaker  1170  may be included in the audio output circuit  1171  of  FIG. 3 . The speaker  1170  may convert an electrical signal into a sound signal. The speaker  1170  may output sound to the outside of the first wireless audio device  1100 . For example, the speaker  1170  may convert an electrical signal into a sound that the user may audibly recognize and output the electrical signal. At least a portion of the speaker  1170  may be disposed inside the housing  1110 . The speaker  1170  may be coupled to the ear tip  1112  through one end of the housing  1110 . The ear tip  1112  may be formed in a cylindrical shape with a hollow formed therein. For example, when the ear tip  1112  is coupled with the housing  1110 , the sound (audio) output from the speaker  1170  may be transferred to an external object (e.g., the user) through the hollow of the ear tip  1112 . 
     According to an embodiment of the disclosure, the first wireless audio device  1100  may include a sensor  1151   a  (e.g., an acceleration sensor, a bone conduction sensor, and/or a gyro sensor) disposed on the second surface of the housing  1110 . The position and shape of the sensor  1151   a  illustrated in  FIG. 11  are not limited thereto. For example, the sensor  1151   a  may be disposed inside the housing  1110  not to be exposed to the outside. The sensor  1151   a  may be located in a position capable of contacting the wearer&#39;s ear or in a portion of the housing  1110  in contact with the wearer&#39;s ear when worn. 
     The ear tip  1112  may be formed of an elastic material (or a flexible material). The ear tip  1112  may assist the first wireless audio device  1100  to be tightly inserted into the user&#39;s ear. For example, the ear tip  1112  may be formed of a silicone material. At least one area of the ear tip  1112  may be deformed according to the shape of the external object (e.g., the shape of the ear kernel). According to various embodiments of the disclosure, the ear tip  1112  may be formed by a combination of at least two of silicone, foam, and plastic material. For example, the area of the ear tip  1112  that is inserted into and touches the user&#39;s ear may be formed of a silicone material, and the area into which the housing  1110  is inserted may be formed of a plastic material. The ear tip  1112  may be detached from the housing  1110  or attached to the housing  1110 . The first electrode  1114  and the second electrode  1115  may be connected with an external power source (e.g., a case) and may receive electrical signals from the external power source. The proximity sensor  1150  may be used to detect the user&#39;s wearing state. The proximity sensor  1150  may be disposed inside the housing  1110 . At least a portion of the proximity sensor  1150  may be disposed to be exposed to the exterior of the first wireless audio device  1100 . The first wireless audio device  1100  may determine whether the first wireless audio device  1100  is worn by the user based on the data measured by the proximity sensor  1150 . For example, the proximity sensor  1150  may include an IR sensor. The IR sensor may detect whether the housing  1110  contacts the user&#39;s body, and the first wireless audio device  1100  may determine whether the first wireless audio device  1100  is worn based on the detection by the IR sensor. The proximity sensor  1150  is not limited to an IR sensor and may be implemented using various types of sensors (e.g., an acceleration sensor or a gyro sensor). The third microphone  1181   c  may be arranged to detect sound in a direction toward the user when the first wireless audio device  1100  is worn. The third microphone  1181   c  may be referred to as an internal microphone. 
       FIG. 12  is a block diagram illustrating a wireless audio device according to an embodiment of the disclosure. 
     Referring to  FIG. 12 , according to various embodiments of the disclosure, a wireless audio device  1200  may be a type of the wearable electronic device  200 . The components of the wireless audio device  1200  of  FIG. 12  may include example software modules. For example, the above-described components may be implemented by the first wireless audio device  1100  or the second wireless audio device. At least some of the components may be omitted. At least some of the components may be implemented as one software module. The components are logically so divided and may correspond to any program, thread, application, or code that performs the same function. 
     A pre-processing module  1210  may perform pre-processing on the sound (audio) (or audio signal) received using an audio reception circuit (e.g., the sound input device  210  of  FIG. 2 ). For example, the pre-processing module  1210  may cancel the echo of the obtained audio signal using an acoustic echo canceller (AEC)  1211 . The pre-processing module  1210  may reduce the noise of the obtained audio signal using a noise suppression (NS)  1212 . The pre-processing module  1210  may reduce the signal of a designated band of the obtained audio signal using a high pass filter (HPF)  1213 . The pre-processing module  1210  may change the sampling rate of the audio input signal using a converter  1214 . For example, the converter  1214  may be configured to perform downsampling or upsampling on the audio input signal. The pre-processing module  1210  may selectively apply at least one of the AEC  1211 , the NS  1212 , the HPF  1213 , or the converter  1214  to the audio signal. 
     A dialog mode module  1220  may determine whether to start and end a dialog mode. For example, the dialog mode module  1220  may detect whether the wearer (e.g., the user) of the wireless audio device  1200  utters using a first voice activity detection (VAD)  1221 . The dialog mode module  1220  may detect whether the wearer utters and an outsider utters using a second VAD  1222 . The dialog mode module  1220  may identify and/or specify the wearer&#39;s utterance duration through the first VAD  1221 . The dialog mode module  1220  may identify and/or specify the outsider&#39;s utterance duration through the first VAD  1221  and the second VAD  1222 . For example, the dialog mode module  1220  may identify and/or specify the outsider&#39;s utterance duration by excluding the duration in which the wearer&#39;s utterance is identified through the first VAD  1221 , of the duration in which utterance is identified through the second VAD  1222 . The dialog mode module  1220  may determine whether to execute and terminate a sound agent using the first VAD  1221 , the second VAD  1222 , and the dialog mode function  1223 . 
     According to an embodiment of the disclosure, the dialog mode module  1220  may detect whether the user utters and whether the outsider utters, using the first VAD  1221  and the second VAD  1222 . In an example, the dialog mode module  1220  may perform at least one of the first VAD  1221  or the second VAD  1222  using the audio signal pre-treated by the pre-processing module  1210  or the audio signal not processed by the pre-processing module  1210 . The wireless audio device  1200  may detect a motion of the wireless audio device  1200  using a sensor  1551   a  (e.g., a motion sensor, an acceleration sensor, and/or a gyro sensor). As an example, if an audio signal (e.g., a sound signal) of a designated magnitude or more is detected in a designated band (e.g., the human voice frequency band), the wireless audio device  1200  may detect the sound signal from the audio signal. When a designated motion is detected during, simultaneously, or substantially simultaneously with the detection of the sound signal, the wireless audio device  1200  may detect the user&#39;s utterance (e.g., wearer&#39;s utterance) based on the sound signal. For example, the designated motion may be a motion detected by the wireless audio device  1200  due to the utterance of the wearer of the wireless audio device  1200 . For example, the motion due to the wearer&#39;s utterance, in the form of a motion or vibration, may be transferred to the motion sensor, acceleration sensor, and/or gyro sensor. The motion due to the wearer&#39;s utterance may be introduced to the motion sensor, acceleration sensor, and/or gyro sensor, as is a bone conductance microphone input. The wireless audio device  1200  may obtain information about the start and end times of the wearer&#39;s utterance based on the designated motion and the sound signal. When the designated motion is not detected during, simultaneously, or substantially simultaneously with the detection of the sound signal, the wireless audio device  1200  may detect the outsider&#39;s utterance (e.g., an utterance from a person (e.g., an outside or the counterpart) other than the wearer) based on the sound signal. The wireless audio device  1200  may obtain information about the start and end times of the outsider&#39;s utterance based on the designated motion and the sound signal. The dialog mode module  1220  may store the information about the start and end times of the user&#39;s utterance or the outsider&#39;s utterance in the memory and determine whether to start or end the dialog mode based on the information stored in the memory. 
     For example, the first VAD  1221  and the second VAD  1222  may be serial processes. When a sound signal is detected using the second VAD  1222 , the wireless audio device  1200  may detect motion using a motion sensor (e.g., an acceleration sensor and/or a gyro sensor), thereby identifying whether the sound signal corresponds to the user&#39;s utterance. 
     For example, the first VAD  1221  and the second VAD  1222  may be parallel processes. For example, the first VAD  1221  may be configured to detect the user&#39;s utterance independently of the second VAD  1222 . The second VAD  1222  may be configured to detect the sound signal regardless of whether the user utters. 
     For example, the wireless audio device  1200  may use different microphones in detecting the user&#39;s utterance and the outsider&#39;s utterance. The wireless audio device  1200  may use an external microphone (e.g., the first microphone  1181   a  and the second microphone  1181   b  of  FIG. 11 ) to detect the outsider&#39;s utterance. The wireless audio device  1200  may use an internal microphone (e.g., the third microphone  1181   c  of  FIG. 11 ) to detect the user&#39;s utterance. When using the internal microphone, the electronic device  1200  may determine whether the wearer utters based on the motion information and the sound signal which is based on the internal microphone. To detect the user&#39;s utterance, the wireless audio device  1200  may determine whether the wearer utters based on the sound signal introduced as a sensor input. The signal introduced as the sensor input may include at least one of an acceleration sensor input or a gyro sensor input. 
     According to an embodiment of the disclosure, the dialog mode module  1220  may determine to start the dialog mode using the first VAD  1221  and/or the second VAD  1222 . In the dialog mode OFF state, the dialog mode module  1220  may determine whether to start the dialog mode. For example, the dialog mode module  1220  may determine to start the dialog mode when the user&#39;s utterance is maintained for a designated time period. As another example, the dialog mode module  1220  may determine to start the dialog mode when the counterpart&#39;s utterance is maintained for a designated time period after the user&#39;s utterance is terminated. 
     According to an embodiment of the disclosure, the dialog mode module  1220  may determine whether to maintain or terminate the dialog mode using the first VAD  1221  and/or the second VAD  1222 . In the dialog mode ON state, the dialog mode module  1220  may determine whether to maintain or terminate the dialog mode. For example, during the dialog mode, the dialog mode module  1220  may determine to end the dialog mode if no sound signal is detected for a designated time period. During the dialog mode, the dialog mode module  1220  may determine to maintain the dialog mode when a sound signal is detected within a designated time period from the end of the previous sound signal. 
     According to an embodiment of the disclosure, the dialog mode module  1220  may determine whether to start and/or end the dialog mode based on the dialog mode function  1223 . The dialog mode function  1223  may detect a dialog mode start and/or end based on a user input. For example, the user input may include the user&#39;s sound command, the user&#39;s touch input, or the user&#39;s button input. 
     According to an embodiment of the disclosure, the dialog mode module  1220  may determine the length of the designated time period based on the ambient sound. For example, the dialog mode module  1220  may determine the length of the designated time period based on at least one of the background noise sensitivity, signal to noise ratio (SNR) value or noise type of the sound obtained by an external microphone. In a noisy environment, the dialog mode module  1220  may increase the length of the designated time period. 
     According to an embodiment of the disclosure, the dialog mode module  1220  may determine whether to start and/or end the dialog mode based on the user&#39;s sound command. In one example, the sound agent module  1230  may detect the user&#39;s sound command instructing to start the dialog mode and transfer, to the dialog mode function  1223 , information indicating the start of the dialog mode in response to detection of the sound command. The sound command instructing to start the dialog mode may include a sound command and a wakeup utterance (e.g., Hi Bixby) to wake up the sound agent. For example, the sound command may have a form, such as “Hi Bixby. Start dialog mode”. As another example, the sound command instructing to start the dialog mode may have a form, such as “Start dialog mode,” which does not include a wakeup utterance. When the dialog mode function  1223  receives information indicating the start of the dialog mode from the sound agent module  1230 , the dialog mode module  1220  may determine to start the dialog mode. In one example, the sound agent module  1230  may detect the user&#39;s sound command instructing to end the dialog mode and transfer, to the dialog mode function  1223 , information indicating the end of the dialog mode in response to detection of the sound command. For example, the sound command instructing to end the dialog mode may include a sound command and a wakeup utterance to wake up the sound agent. The sound command may have a form, such as “Hi Bixby. End dialog mode”. For example, the sound command instructing to end the dialog mode may have a form, such as “End dialog mode,” which does not include a wakeup utterance. When the dialog mode function  1223  receives information indicating the end of the dialog mode from the sound agent module  1230 , the dialog mode module  1220  may determine to end the dialog mode. 
     According to an embodiment of the disclosure, the dialog mode module  1220  may determine whether to start and/or end the dialog mode based on the user&#39;s touch input. For example, the electronic device  101  may provide a UI for controlling the dialog mode of the wireless audio device  1200 . Through the UI, the electronic device  101  may receive a user input for setting activation or deactivation of the dialog mode. If the user input instructing activation of the dialog mode is received, the electronic device  101  may transmit a signal instructing to start the dialog mode to the wireless audio device  1200 . If the dialog mode function  1223  receives information indicating the start of the dialog mode from the signal, the dialog mode module  1220  may determine to start the dialog mode. If a user input instructing deactivation of the dialog mode is received through the UI, the electronic device  101  may transmit a signal instructing to end the dialog mode to the wireless audio device  1200 . If the dialog mode function  1223  obtains information indicating the end of the dialog mode from the signal, the dialog mode module  1220  may determine to end the dialog mode. 
     According to an embodiment of the disclosure, if the dialog mode module  1230  determines to start or end the dialog mode, the wireless audio device  1200  transmits a signal indicating that the start or end of the dialog mode has been determined to the electronic device  101 . The electronic device  101  may provide information indicating that the start or end of the dialog mode has been determined, obtained from the signal, through the UI for controlling the dialog mode of the wireless audio device  1200 . 
     According to an embodiment of the disclosure, the dialog mode module  1220  may determine whether to start and/or end the dialog mode based on the user&#39;s button input. For example, the wireless audio device  1200  may include at least one button (e.g., the button  1113  of  FIG. 11 ). The dialog mode function  1223  may be configured to detect a designated input (e.g., a double tap or a long press) to the button. If an input instructing to start the dialog mode is received through the button, the dialog mode module  1220  may determine to start the dialog mode. If an input instructing to end the dialog mode is received through the button, the dialog mode module  1220  may determine to end the dialog mode. 
     According to an embodiment of the disclosure, the dialog mode function  1223  may be configured to interact with the sound agent module  1230 . For example, the dialog mode function  1223  may obtain information indicating whether the utterance is for a sound agent invocation from the sound agent module  1230 . For example, the wearer&#39;s utterance maintained for a designated time or longer may be detected by the first VAD  1221 . In this case, the dialog mode module  1220  may identify whether the wearer&#39;s utterance is for the invocation of the sound agent using the dialog mode function  1223 . When the dialog mode function  1223  identifies, using the sound agent module  1230 , that the sound agent invocation has been performed by the corresponding utterance, the dialog mode module  1220  may disregard the corresponding utterance. For example, even when the corresponding utterance lasts for a designated time or longer, the dialog mode module  1220  may not determine to start the dialog mode only with the corresponding utterance. For example, the sound agent module  1230  may identify a sound command instructing to start the dialog mode from the corresponding utterance. In this case, the sound agent module  1230  may transfer the signal instructing to start the dialog mode to the dialog mode module  1220 , and the dialog mode module  1220  may determine to start the dialog mode. In other words, in this case, the dialog mode module  1220  may determine to start the dialog mode based on the instruction of the sound agent module  1230  rather than the length of the utterance itself. 
     According to an embodiment of the disclosure, the dialog mode module  1220  may determine to end the dialog mode based on the operation time of the dialog mode. For example, after a predetermined time elapses after the dialog mode is turned on, the dialog mode module  1220  may determine to end the dialog mode. 
     According to an embodiment of the disclosure, the sound agent module  1230  may include a wakeup utterance recognition module  1231  and a sound agent control module  1232 . In one example, the sound agent module  1230  may further include a sound command recognition module  1233 . The wakeup utterance recognition module  1231  may obtain an audio signal using the audio reception circuit  210  and may recognize a wakeup utterance (e.g., Hi Bixby) from the audio signal. If a designated sound command is recognized, the wakeup utterance recognition module  1231  may control the sound agent using the sound agent control module  1232 . For example, the sound agent control module  1232  may transfer the received sound signal to the electronic device (e.g., the electronic device  101 ) and may receive a task or command corresponding to the sound signal from the electronic device  101 . For example, when the sound signal instructs to adjust the volume, the electronic device  101  may transfer a signal instructing to adjust the volume to the wireless audio device  1200 . The sound command recognition module  1233  may obtain an audio signal using the audio reception circuit  210  and may recognize a designated sound command from the audio signal. In one example, the designated sound utterance may include a sound command (e.g., start dialog mode, end dialog mode) for controlling the dialog mode. The sound command recognition module  1233  may perform the function corresponding to the designated sound command if the designated sound command is recognized even without recognizing the wakeup utterance. For example, the sound command recognition module  1233  may transmit a signal instructing to end the dialog mode to the electronic device  101  if recognizing an utterance of a designated command, such as “end dialog mode”. For example, the sound command recognition module  1233  may perform the function corresponding to the designated sound command without interaction with the sound agent. The electronic device  101  may perform sound control of the wireless audio device  1200 , which is described below, in response to the signal instructing to end the dialog mode. 
     According to an embodiment of the disclosure, the dialog mode module  1220  may transfer the determination for the dialog mode (e.g., the end of the dialog mode or the start of the dialog mode) to the dialog mode control module  1250 . The dialog mode control module  1250  may control the function of the wireless audio device  1200  according to activation and/or deactivation of the dialog mode. For example, the dialog mode control module  1250  may control the output sound of the wireless audio device  1200  using the sound control module  1240  according to activation and/or deactivation of the dialog mode. 
     For example, the sound control module  1240  may include an active noise canceling (ANC) module  1241  and an ambient sound control module  1242 . The ANC module  1241  may be configured to obtain ambient sound and perform noise cancellation based on the ambient sound. For example, the ANC module  1241  may obtain ambient sound using an external microphone and perform noise cancellation using the obtained ambient sound. The ambient sound control module  1242  may be configured to provide ambient sounds to the wearer. For example, the ambient sound control module  1242  may be configured to obtain ambient sound using an external microphone and output the obtained ambient sound using the speaker of the wireless audio device  1200 , providing the ambient sound. 
     According to an embodiment of the disclosure, if the dialog mode starts, the dialog mode control module  1250  may control the output sound of the wireless audio device  1200  using the sound control module  1240 . For example, the dialog mode control module  1250  may deactivate the ANC to activate the ambient sound in response to the start of the dialog mode. As another example, when music is being output from the wireless audio device  1200 , the dialog mode control module  1250  may reduce the volume level of the music being output by a predetermined rate or more or set it to mute in response to the start of the display mode. The user of the wireless audio device  1200  may clearly hear ambient sounds as the dialog mode starts. 
     According to an embodiment of the disclosure, if the dialog mode ends, the dialog mode control module  1250  may control the output sound of the wireless audio device  1200  using the sound control module  1240 . For example, the dialog mode control module  1250  may restore the ANC settings and/or the ambient sound settings to the settings before the dialog mode starts in response to the end of the dialog mode and deactivate the ambient sound. For example, before starting the dialog mode, the dialog mode control module  1250  may store the ANC settings and/or the ambient sound settings in the memory. If the display mode ends, the dialog mode control module  1250  may activate or deactivate ANC and/or ambient sound depending on the ANC settings and/or ambient sound settings stored in the memory. 
     As another example, the dialog mode control module  1250  may restore the output sound of the wireless audio device  1200  to the settings before the dialog mode starts, in response to the end of the dialog mode. For example, when music is being output from the wireless audio device  1200  before the dialog mode starts, the dialog mode control module  1250  may store music output sound settings in the memory. If the dialog mode ends, the dialog mode control module  1250  may restore the music output sound to the music output sound settings stored in the memory. The dialog mode control module  1250  may reduce the media output volume to a designated value or mute, according to the settings, in the dialog mode. In the dialog mode, the wireless audio device  1200  may output a notification (e.g., a response to the user&#39;s utterance) of the sound agent, independently of the volume of the dialog mode. For example, the wireless audio device  1200  may output a notification (e.g., a TTS-based response) of the sound agent, in a designated volume value in the dialog mode. 
     According to an embodiment of the disclosure, the dialog mode control module  1250  may control the output sound using the sound control module  1240  during the operation of the dialog mode. For example, the dialog mode control module  1250  may control the intensity of the ANC and/or ambient sound. The dialog mode control module  1250  may control the gain value of the ambient sound to amplify the intensity of the ambient sound. The dialog mode control module  1250  may amplify only the section in which a sound exists in the ambient sound or a frequency band corresponding to a sound. In the dialog mode, the dialog mode control module  1250  may reduce the intensity of ANC. The dialog mode control module  1250  may control the output volume of the audio signal. 
     Tables 7 and 8 below show examples of sound control of the dialog mode control module  1250  according to the start (e.g., ON) and end (e.g., OFF) of the dialog mode.

     Referring to Table 7, the wearer of the wireless audio device  1200  may be listening to music using the wireless audio device  1200 . For example, the wireless audio device  1200  may output music while performing ANC. For example, the wireless audio device  1200  may output music in a first volume. As the dialog mode starts, the dialog mode control module  1250  may activate ambient sound and deactivate ANC. In this case, the dialog mode control module  1250  may reduce the volume of the music being output to a designated value or less or may decrease it by a designated rate. For example, the dialog mode control module  1250  may reduce the volume of the music being output to a second value in the dialog mode. As the dialog mode ends, the dialog mode control module  1250  may restore settings related to the output sound. For example, the dialog mode control module  1250  may activate ANC and deactivate ambient sound. Further, the dialog mode control module  1250  may increase the volume of the music being output to the first value.

     Referring to Table 8, the wearer of the wireless audio device  1200  may be listening to music using the wireless audio device  1200 . For example, the wireless audio device  1200  may output music without applying ANC. For example, the wireless audio device  1200  may output music in a first volume. As the dialog mode starts, the dialog mode control module  1250  may activate ambient sound and keep ANC inactive. In this case, the dialog mode control module  1250  may reduce the volume of the music being output to a designated value or less or may decrease it by a designated rate. For example, the dialog mode control module  1250  may reduce the volume of the music being output to a second value in the dialog mode. As the dialog mode ends, the dialog mode control module  1250  may restore settings related to the output sound. For example, the dialog mode control module  1250  may keep ANC inactive and deactivate ambient sound. Further, the dialog mode control module  1250  may increase the volume of the music being output to the first value. 
     In the examples of Tables 7 and 8, it has been described that the wireless audio device  1200  deactivates the ambient sound when the dialog mode is not set, but embodiments of the disclosure are not limited thereto. For example, even when the dialog mode is not set, the wireless audio device  1200  may activate ambient sound according to the user&#39;s settings. 
     According to an embodiment of the disclosure, an environment classification module  1260  may obtain an audio signal using an audio reception circuit and classify the environment based on the audio signal. For example, the environment classification module  1260  may obtain at least one of background noise, signal to noise ratio (SNR), or noise type from the audio signal. The environment classification module  1260  may detect the environment based on the intensity of the background noise, the SNR, or the noise type. For example, the environment classification module  1260  may identify the environment of the wireless audio device  1200  by comparing the environment information stored in the memory with at least one of background noise intensity, SNR, and noise type. For example, the environment classification module  1260  may control the output sound based on the identified environment. 
     For example, in a state in which the dialog mode is activated, the environment classification module  1260  may control the output sound based on the identified environment. The environment classification module  1260  may control the ambient sound based on the intensity and/or SNR of the background noise. For example, the environment classification module  1260  may determine to amplify the overall output of the ambient sound or the sound band of the ambient sound or amplify a designated sound (e.g., alarm or siren) of the ambient sound. For example, the environment classification module  1260  may determine the intensity of ANC. For example, the environment classification module  1260  may adjust parameters (e.g., coefficients) of a filter for ANC. In the above-described example, the environment classification module  1260  identifies the environment using the audio signal, but embodiments of the disclosure are not limited thereto. For example, the environment classification module  1260  may identify the environment based on Wi-Fi information and/or GPS information. 
     According to an embodiment of the disclosure, the environment classification module  1260  may control the dialog mode based on the identified environment. For example, the environment classification module  1260  may activate the dialog mode based on the identified environment. If the environment classification module  1260  determines that the user is in an environment in which ambient sounds are to be heard, the environment classification module  1260  may activate the dialog mode using the dialog mode control module  1250  and provide the ambient sound to the user according to the dialog mode. For example, when the user is in a dangerous environment (e.g., an environment in which a siren sound is detected), the environment classification module  1260  may activate the dialog mode. 
     According to an embodiment of the disclosure, the electronic device  101  may display a user interface indicating the end or start of the dialog mode on the display  360 . The electronic device  101  may provide the user interface in a manner synchronized with the dialog mode of the wireless audio device  1200 . The electronic device  101  may display the user interface when the electronic device  101  determines to end or start the dialog mode or receives a signal instructing to end or start the dialog mode from the wireless audio device  1200 . For example, if the dialog mode starts, the electronic device  101  may display a first user interface including information indicating that the dialog mode is set. The first user interface may include an interface for controlling output sound settings in the dialog mode. For example, if the dialog mode ends, the electronic device  101  may display a second user interface including information indicating that the dialog mode is terminated. The electronic device  101  may display the first user interface and the second user interface on an execution screen of an application (e.g., a wearable application) for controlling the wireless audio device  1200 . 
     According to an embodiment of the disclosure, the dialog mode module  1220  may determine to start and end the dialog mode based on whether it is worn. For example, when the wireless audio device  1200  is worn by the user, the dialog mode module  1220  may start the dialog mode based on the user&#39;s (e.g., wearer&#39;s) utterance or user input. When the wireless audio device  1200  is not worn by the user, the dialog mode module  1220  may not start the dialog mode even when the user&#39;s utterance is detected. 
     For example, each of the first wireless audio device  1100  and the second wireless audio device (not shown) may include the components of the wireless audio device  1200  shown in  FIG. 12 . Each of the first wireless audio device  1100  and the second wireless audio device may be configured to determine whether to start the dialog mode. According to an embodiment of the disclosure, if the first wireless audio device  1100  or the second wireless audio device determines to start the dialog mode, the first wireless audio device  1100  and the second wireless audio device may be configured to operate in the dialog mode. For example, the first wireless audio device  1100  or the second wireless audio device that has determined to start the dialog mode may be configured to transmit a signal instructing to start the dialog mode to another wireless audio device and/or the electronic device  101 . According to an embodiment of the disclosure, when both the first wireless audio device  1100  and the second wireless audio device determine to start the dialog mode, the first wireless audio device  1100  and the second wireless audio device may be configured to operate in the dialog mode. For example, the first wireless audio device  1100  or the second wireless audio device that has determined to start the dialog mode may identify whether the other wireless audio device has determined to start the dialog mode and, if both the first wireless audio device  1100  and the second wireless audio device determine to start the dialog mode, the first wireless audio device  1100  and the second wireless audio device may operate in the dialog mode. As another example, the first wireless audio device  1100  or the second wireless audio device that has determined to start the dialog mode may transmit a signal instructing to start the dialog mode to the electronic device  101 . If receiving signals instructing to start the dialog mode from both the first wireless audio device  1100  and the second wireless audio device within a designated time, the electronic device  101  may transmit a signal to allow the first wireless audio device  1100  and the second wireless audio device to operate in the dialog mode. 
     According to various embodiments of the disclosure, an electronic device (e.g., the electronic device  101 ) may comprise a communication circuit (e.g., the communication module  190 ), a display (e.g., the display module  160 ), at least one sensor (e.g., the sensor module  176 ), and at least one processor (e.g., the processor  120 ).
