To provide an in-vehicle communication support system for improving an SN ratio of utterance voice to be output from a speaker with a comparatively efficient structure.SOLUTION: A right-seat processing section 11 includes: a filter HR 111 for defining the voice of a user on a right front seat as right front seat voice and converting the right front seat voice being output from a left front seat microphone PL arranged in a footrest of a left front seat into the right front seat voice which is collected by a right seat virtual microphone PVR being a virtual microphone positioned on the left side of a footrest of a right front seat; a delay section Z-TR 112 for outputting, by delaying, the output of a right front seat microphone PR positioned on the right side of the footrest of the right front seat; a filter WRA 113 for extracting the right front seat voice being output by the filter HR 111; a filter WRB 114 for extracting the right front seat voice being output by the delay section Z-TR 112; and a right adder 115 for adding the output of the filter WRA 113 to the output of the filter WRB 114, so as to output it as a right front seat utterance voice signal SR.SELECTED DRAWING: Figure 3
【課題】比較的効率的な構成でスピーカから出力する発話音声のSN比を向上する「車内コミュニケーション支援システム」を提供する。【解決手段】右前席のユーザの音声を右前席音声として、右席処理部11は、左前席のフットレストに配置された左前席マイクPLの出力中の右前席音声を右前席のフットレストの左側に位置する仮想のマイクである右席仮想マイクPVRで収音した右前席音声に変換するフィルタHR111、右前席のフットレストの右側に位置する右前席マイクPRの出力を遅延して出力する遅延部Z-TR112、フィルタHR111の出力中の右前席音声を抽出するフィルタWRA113、遅延部Z-TR112の出力中の右前席音声を抽出するフィルタWRB114、フィルタWRA113とフィルタWRB114の出力を加算し右前席発話音声信号SRとして出力する右加算器115を備えている。【選択図】図3
