A mobile phone 10 is installed with a plurality of applications, and an arbitrary operation by a voice input can be performed. The mobile phone 10 stores a history of an application performed by a user in a RAM (46). If the user performs a voice input saying “Use camera”, “standard camera” and “AR camera” that are applications in a category of “camera” are acquired as a search result. At this time, the search result is narrowed down based on a use history of the user. If a use frequency of “standard camera” is higher than that of “AR camera”, “standard camera” is performed. |
