Patent ID: 7620388

Claim:
A portable telephone set capable of conversation simulation with a user, comprising: a scenario information storage unit storing conversation simulation scenario information stored in the portable telephone set as conversation simulation data prepared depending on a conversation simulation date and time and stored in the portable telephone set itself as the conversation simulation data; an acquisition unit acquiring the scenario information stored as associated with date-and-time information of a starting point of the conversation simulation from the scenario information storage unit; and an execution unit executing the conversation simulation with the user according to the scenario information acquired by the acquisition unit, wherein the scenario information storage unit stores conversation simulation scenario information prepared further depending on a property of a conversation simulation partner and the scenario information stored as further associated with the conversation simulation partner in the portable telephone set as the conversation simulation data, and the acquisition unit acquires the scenario information stored as associated with the conversation simulation partner from the scenario information storage unit and the scenario information describes first information about a sentence as a framework of conversation simulation, second information about which storage unit of the portable telephone set retrieves what conversation simulation data and embeds the retrieved data in which position of the framework sentence, and third information about a no-conversation time for an answer.
