The present invention provides a travel direction device in which a user can listen to voice directions or warning voice direction about a traveling route. The travel direction device according to the present invention sets a direction about the traveling route, and if the user drives the same traveling route a plurality of times, the direction is given less frequently than a number of times the user drives the traveling route. Accordingly, the voice direction is not given all the time, thus not annoying for the user who uses the same route repeatedly. Consequently, the user would not turn off the voice direction function itself, and thus, the voice direction function can be used effectively.
