First Claim
1. A vehicle navigation device for providing voice guidance for guiding a vehicle along a set route, which comprises:
- main storage means for storing map data and route guidance voice data of individual phrases;
read means for reading out the route guidance voice data from said main storage means in the form of guidance instructions relating to intersections or road junctions on the set route, said guidance instructions including instructions each formed by a series of selected phrases from the stored individual phrases;
voice output means for outputting the route guidance voice data, read by said read means, directly as a voice message;
input means for inputting information for setting the route, said information including a destination;
current-position detection means for detecting a current position of the vehicle; and
control means for controlling execution of a routine providing guidance including voice guidance during travel along the set route, said control means including route setting means for setting a route from the current position to the destination as the set route, route storage means for temporarily storing the set route, and voice data edit means for selecting phrases including combinations of phrases forming instructions from the stored individual phrases relating to corresponding intersections or road junctions on the set route prior to output by said voice output means as the voice message, said control means controlling said read means so that said read means reads voice data out for each combination of phrases forming an instruction in a sequence of phrases from said storage means and controlling said voice output means to output the sequence of phrases concurrently with the reading of the sequence of phrases so that the voice message is output a predetermined distance before a guide point on the set route.

Abstract
A vehicle navigation device provides route guidance by voice or the like in accordance with a preset route. The system includes data storage for storing data such as data relating to a map and route guidance voice data. The system reads out the route voice guidance data from storage and outputs the route voice guidance data directly as voice guidance. An input device allows for inputting information for setting or instructing the route guidance. A current position detector detects current position of the vehicle and a controller sets a route from the current position to a destination, with temporary storage of that set route. A voice data editor edits the combination of phrases of the guidance message relating to an intersection, a diverging point, etc., on the set route in temporary storage. The controller controls the reading out of the voice data from storage in sequential fashion and outputs the read voice data at a predetermined distance before a guide point utilizing the edited combination of phrases.
