A mobile terminal, comprising: a display; a proximity sensor configured to sense proximity of an object; an audio output unit; a microphone unit; and a controller configured to: - deactivate the display, - enter the mobile terminal into a standby mode while maintaining the proximity sensor in an activated state; - in response to sensing the proximity of the object through the proximity sensor, activate the microphone and activate a voice recognition function, - in response to receiving a first voice signal for requesting first event information through the microphone, execute a first function of an application corresponding to first text converted from the first voice signal, and - cause the audio output unit to output audio data corresponding to an execution of the first function while the display is deactivated, - in response to receiving a second voice signal for changing the first function, cancel execution of the first function of the application, and - execute a second function of the application corresponding to second text converted from the second voice signal, wherein the output audio data corresponds to information collected about a previous event that occurred on the mobile terminal. a display; a proximity sensor configured to sense proximity of an object; an audio output unit; a microphone unit; and a controller configured to: - deactivate the display, - enter the mobile terminal into a standby mode while maintaining the proximity sensor in an activated state; - in response to sensing the proximity of the object through the proximity sensor, activate the microphone and activate a voice recognition function, - in response to receiving a first voice signal for requesting first event information through the microphone, execute a first function of an application corresponding to first text converted from the first voice signal, and - cause the audio output unit to output audio data corresponding to an execution of the first function while the display is deactivated, - in response to receiving a second voice signal for changing the first function, cancel execution of the first function of the application, and - execute a second function of the application corresponding to second text converted from the second voice signal, - deactivate the display, - enter the mobile terminal into a standby mode while maintaining the proximity sensor in an activated state; - in response to sensing the proximity of the object through the proximity sensor, activate the microphone and activate a voice recognition function, - in response to receiving a first voice signal for requesting first event information through the microphone, execute a first function of an application corresponding to first text converted from the first voice signal, and - cause the audio output unit to output audio data corresponding to an execution of the first function while the display is deactivated, - in response to receiving a second voice signal for changing the first function, cancel execution of the first function of the application, and - execute a second function of the application corresponding to second text converted from the second voice signal, wherein the output audio data corresponds to information collected about a previous event that occurred on the mobile terminal.
