Abstract
Dialogue apparatus configured to carry out a dialogue with a driver and including storage, concentration degree measuring and dialogue units. The storage unit maintains a preference database in which a dialogue candidate of content for a dialogue with the driver and a dialogue effect indicating a degree of improving driver's degree of concentration on driving, are associated with each other. The concentration degree measuring unit measures the driver's degree of concentration on driving. The dialogue unit selects a dialogue candidate based on the dialogue effect in the preference database when the degree of concentration measured by the concentration degree measuring unit falls below a predetermined threshold, then carries out a dialogue by the selected dialogue candidate, and based on the degree of concentration before and after carrying out the dialogue, calculates the dialogue effect of the dialogue, and updates the dialogue effect of the preference database.
