The present invention provides an in-vehicle communication assistance system that improves the SN ratio of speech sound output from a speaker with a relatively efficient configuration. A right seat processor (11) uses the sound of a user of a right front seat as the right front seat sound, and is provided with: a filter (HR111) that converts the right front seat sound in the output of a left front seat microphone (PL) disposed on a pedal of the left front seat into the right front seat sound picked up by a right seat virtual microphone (PVR) that is a virtual microphone located on the left side of the pedal of the right front seat; a delay unit (Z-TR112) for delaying and outputting the output of a right front seat microphone (PR) positioned on the right side of a pedal of the right front seat; a filter (WRA113) that extracts a right front seat sound from the output of the filter (HR111); a filter (WRB114) that extracts the right front seat sound from the output of the delay unit (Z-TR112); and a right adder (115) that adds the output of the filter (WRA113) and the output of the filter (WRB114) and outputs the result as a right front seat speech sound signal (SR).
本发明提供以比较高效的结构提高从扬声器输出的讲话声音的SN比的车内交流辅助系统。将右前座的用户的声音作为右前座声音,右座处理器(11)具备:滤波器(HR111),将在左前座的脚踏板上配置的左前座麦克风(PL)的输出中的右前座声音变换为由位于右前座的脚踏板左侧的虚拟的麦克风即右座虚拟麦克风(PVR)拾音到的右前座声音;延迟部(Z-TR112),将位于右前座的脚踏板右侧的右前座麦克风(PR)的输出延迟并输出;滤波器(WRA113),提取滤波器(HR111)的输出中的右前座声音;滤波器(WRB114),提取延迟部(Z-TR112)的输出中的右前座声音;以及右加法器(115),将滤波器(WRA113)和滤波器(WRB114)的输出相加,并作为右前座讲话声音信号(SR)输出。
