AI Technical Summary

Technical Problem

Conventional call processing technologies using pseudo-generated environmental sounds fail to accurately convey to the call partner that the vehicle occupant is driving, leading to uncertainty and potential misinterpretation.

Method used

A call processing apparatus that selectively retains specific driving sounds, such as turn signal and tire noise, while removing other operating noises, ensuring the call partner understands the occupant is driving.

Benefits of technology

Accurately conveys the driving state to the call partner, preventing misinterpretation and maintaining call quality by retaining non-interfering driving sounds.

Abstract

To provide a call processing device and a call processing method that can make the other party understand with high precision that the person on the other end of the call is driving.SOLUTION: A call processing device according to an embodiment includes a control portion. When a passenger is talking on a phone call, the control portion transmits, to the other party, adjusted voice generated by performing a removal process that removes other driving sounds while leaving a specific driving sound among the driving sounds that accompany the driving of a vehicle, from the sound collected by a microphone inside the vehicle when the passenger is on a phone call.SELECTED DRAWING: Figure 2
