COMMUNICATION TERMINAL DEVICE, PROGRAM FOR COMMUNICATION TERMINAL DEVICE, AND CONTROL METHOD FOR COMMUNICATION TERMINAL DEVICE

摘要

PROBLEM TO BE SOLVED: To improve operability in executing an application program while performing a voice communication.SOLUTION: A communication terminal device displays on a display part a GUI image for reception capable of selecting a first reception mode in which a speech is performed by emitting a telephone voice from a first speaker or a second reception mode in which a speech is performed by emitting a telephone voice from a second speaker in response to receiving a speech request by a telephone function part. Upon receiving operation input to a portion corresponding to the second reception mode in an operation input receiving part in the GUI image for reception, the second speaker is activated. After the second speaker is activated, in response to detecting the absence of an object as long as or longer than a predetermined time by a proximity sensor, an image to be displayed on the display part is switched from the GUI image for reception to a GUI image for application start for executing an application program by an application execution part.SELECTED DRAWING: Figure 2
