Claim 10

Dependent Claim 72 words

An apparatus according to claim 7, wherein when the content of the selected voice data includes an instruction for the vehicle to change directions along the route, said voice output means outputs voice data in a manner that creates an acoustic image which causes a driver of the vehicle to perceive that sound is coming from a position that corresponds to a direction in which the vehicle is instructed to be driven.

Claim 11

Dependent Claim 93 words

An apparatus according to claim 8, wherein said voice output means creates an acoustic image causing the driver to perceive that sound is coming from a position that corresponds to the direction in which the vehicle is instructed to be driven along the route of the vehicle, the perceived position from which the sound is coming from being changed as the vehicle travels, so that the direction from which the sound is perceived to come from and the perceived distance from the perceived sound to the driver change as the vehicle position changes.

Claim 12

Dependent Claim 74 words

An apparatus according to claim 9, further comprising: vehicle speed detection means for detecting a speed of the vehicle; and direction detection means for detecting a direction in which the vehicle is being navigated; wherein said voice output means creates an acoustic image based upon the voice data in accordance with the vehicle speed detected by said vehicle speed detection means, and further in accordance with the direction detected by said direction detection means.
