1. An on-vehicle guidance apparatus that provides required information for a passenger, said on-vehicle guidance apparatus comprising:
- a controller comprising;
an output sound controller configured to acquire a sound volume setting of onboard equipment;
a sound volume determining unit configured to determine whether or not said sound volume setting is smaller than a predetermined threshold; and
a guidance output controller configured to issue a command for carrying out voice guidance in response to a determination signal from said sound volume determining unit at a time when said sound volume setting becomes smaller than said predetermined threshold.

2. An on-vehicle guidance apparatus that provides required information for a passenger, said on-vehicle guidance apparatus comprising:
-
a vehicle velocity acquiring device configured to acquire a velocity of a vehicle; a sound input device configured to acquire an environmental sound in a cabin; a controller configured to; determine a sound volume of a conversation in the cabin on a basis of a noise sound volume corresponding to the velocity of the vehicle acquired by said vehicle velocity acquiring device, and a sound volume of the environmental sound in the cabin acquired by said sound input device to determine whether or not said conversation sound volume is smaller than a predetermined threshold, and issue a command for carrying out voice guidance in response to a determination that said conversation sound volume becomes smaller than said predetermined threshold. - View Dependent Claims (3, 4)
