Abstract: A signal processing apparatus includes a generator, an output controller, and an echo canceller. The generator generates an output sound signal by combining an over-the-phone sound signal with a system sound signal different from the over-the-phone sound signal. The output controller outputs, to a loudspeaker, the output sound signal generated by the generator. The echo canceller cancels the output sound signal from an input sound signal input via a microphone located in a vicinity of the loudspeaker. The output controller suppresses a level of the system sound signal to be output from the loudspeaker so as not to be greater than a predetermined value within a range in which a volume value for the over-the-phone sound signal is settable.

Abstract: Systems and methods for providing geo-tagged vehicle-to-vehicle communication to a follower vehicle during off-road caravanning. In some embodiments, verbal instructions spoken by a leader driver are captured by the vehicle-to-vehicle communication system, tagged with geospatial location information, and broadcast to follower vehicles. Follower vehicles can receive the broadcast verbal instructions, and the system can cause the verbal instructions to be reproduced when the follower vehicle is determined to be within a threshold distance of the geospatial location where the leader driver gave the verbal instructions. The verbal instructions can be accompanied by visual data, such as images and videos. The system can add navigation and landmark markers in the visual data to enhance a leader driver's geo-tagged instructions. A message path can formed from several verbal instructions spoken by the leader driver.
