Abstract
A navigation device, installed on a vehicle to enable information to be provided to an occupant of the vehicle, includes a display section providing a display of an image to the occupant of the vehicle, a speech recognition section executing speech recognition processing for a voice input relating to a speech recognition object word that forms a word to be an objective for speech recognition, and an information providing processor section compelling a predetermined image to be displayed on the display section depending on a recognized content resulting through the speech recognition processing in the presence of recognition of the speech recognition object word resulting through the speech recognition processing. The speech recognition section executes second speech recognition processing for the speech recognition object word except for the speech recognition object word present in the image currently displayed in the display section in the presence of a failure in recognition of the speech recognition object word.
