Abstract: A method, device, a non-transitory computer-readable recording medium for controlling a voice signal by an electronic device including a first microphone, a second microphone, a communication interface, and a processor are provided. The method includes acquiring a first voice signal by using the first microphone; acquiring a second voice signal by using the second microphone; confirming a telephone call mode for performing, by the electronic device, a telephone call with an external electronic device; adjusting a first output attribute corresponding to the first voice signal or a second output attribute corresponding to the second voice signal, based on the telephone call mode; and transmitting the adjusted first voice signal or the adjusted second voice signal to the external electronic device by using the communication interface.

Abstract: An electronic device is provided. The electronic includes a camera module and a processor configured to capture at least one image of an object using the camera module, obtain a sound using a microphone operably connected to the processor when the at least one image is captured, determine whether the sound is related to the object, when the sound is determined to be unrelated to the object, change at least one attribute of the sound and store the changed at least one attribute of the sound.

Abstract: An apparatus and a method for controlling the use of a SIM card mounted in a mobile terminal by employing a fraud technology includes comparing data related to the SIM card received from a network to information read from the SIM card in the terminal as part of a terminal initialization process and generating a control signal to cause an RF antenna switch to open or close an RF antenna loop structure in order to disable or enable a requested SIM card function. The data received form the network and the information read from the SIM card in the terminal include subscriber information and transportation card information that allow a determination of whether a user requesting a SIM card function is the subscriber entitled to access the function. If the data received form the network and the information read from the SIM card are identical, the requested SIM card function is approved.
