Abstract: An example electronic device includes a display, a communication circuit, a memory, and at least one processor configured to, based on a signal for requesting transmission of identification information including a call word for using first mode of an artificial intelligence assistant function of the electronic device being received, from another electronic device, through the communication circuit using first communication method, control the display to display a user interface for requesting user confirmation for transmission of the identification information; control the communication circuit to transmit the identification information to the another electronic device as a result of user confirmation through the user interface; and receive information for using a second communication method from the another electronic device.

Abstract: A communication system and operating method use a home gateway. A method of a terminal in a communication system using a home gateway includes transmitting a service request signal using the home gateway to an adjacent node; receiving information of at least one home gateway of other user from the adjacent node; and transmitting and receiving signals to and from the at least one home gateway of other user. A method of a home gateway in the communication system using the home gateway includes receiving information of a user of other home gateway from a home gateway server; and transmitting and receiving signals to and from a user terminal of the other home gateway.

Abstract: A cleaning robot is provided. The cleaning robot includes a main body, a moving assembly to move the main body around a home, an imaging unit to obtain images around the main body, a controller to generate a map of the home using the obtained images, and a communication unit to transmit the generated map to a home monitoring apparatus. A procedure to match location and type information of electric devices to a two-Dimensional (2D) or three-Dimensional (3D) map of the home may be automated. As described above, the map of the home may be realistically generated by utilizing a map generated by the cleaning robot and inconvenience experienced by a user to manually register electric devices located in each room of the home may be solved by automatically registering the electric devices.

Abstract: A method and apparatus for diagnosing a user's health state are provided. The apparatus includes including a voice detecting unit which detects and monitors a user's voice; a voice analyzing unit which extracts a voice feature from a voice detected by the voice detecting unit, based on a health state to be diagnosed; a voice diagnosing unit which diagnoses a health state of the user by comparing the voice feature extracted by the voice analyzing unit with an abnormal state reference, and which monitors a change in the health state; and a diagnosis outputting unit which outputs information regarding the health state and a health state change diagnosed by the voice diagnosing unit.

Abstract: A method and an apparatus for playout scheduling in a Voice over Internet Protocol (VoIP) system are provided. The method includes acquiring Pulse Code Modulation (PCM) samples by decoding a received packet; setting a first scale ratio according to a length of PCM samples stored in a playout buffer based on a preset scale ratio table; setting a second scale ratio by predicting a packet delay; setting a final scale ratio using the first scale ratio and the second scale ratio; and adjusting the length of the acquired PCM samples at the final scale ratio.

Abstract: A method and apparatus for expanding a bandwidth of an input narrowband voice signal is provided. The narrowband voice signal is analyzed separately for each frame, and a Degree of Voicing (DV) and a Degree of Stationary (DS) are calculated depending on the analysis. A Degree of Difficulty of Bandwidth Expansion (DDBWE) of the narrowband voice signal is calculated based on DV and DS. Bandwidth expansion is controlled according to DDBWE.

Abstract: A separable mobile terminal device includes a main module to execute main functions in order to drive a mobile terminal and a user module to inform a user of visual and aural elements. At least one of the main module and the user module has a control unit to determine whether to execute the interworking between the main module and the user module depending on whether the main module and the user module are connected and whether the interworking between the main module and the user module is required. Each of the main module and the user module has an interface unit to enable data transmission/reception between the modules, and a battery to supply driving power to each respective module. Each of the main module and the user module has a connection means, so that the main module and the user module can be connected with or separated from each other via the connection means.
