To provide an "in-vehicle communication support system" for canceling an unnecessary sound and relaying an utterance voice.SOLUTION: A transfer function of a first variable filter 71 is updated so as to output a cancel sound C for minimizing a level of a signal obtained by subtracting an output of an auxiliary filter 75 for generating a correction signal for correcting a difference between positions of a first seat microphone 5 and a first seat from an output M of the first seat microphone 5. A selector 6 uses an utterance voice Dp output from a second seat speaker 4 as an input of the first variable filter 71 in an ICC mode for outputting an utterance voice of a user of the first seat from the second seat speaker 4, and uses an output sound A2 of a second seat audio source 2 output from the second seat speaker 4 as an input of the first variable filter 71 in a non-ICC mode. The utterance voice Dp is generated by removing a component of the cancel sound C from the output M of the first seat microphone 5.SELECTED DRAWING: Figure 3

    【課題】不要音をキャンセルし発話音声を中継する「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】第1席マイク5の出力Mから、第1席マイク5と第1席の位置の差を補正する補正信号を生成する補助フィルタ75の出力を減じた信号のレベルが最小になるキャンセル音Cを出力するように第1可変フィルタ71の伝達関数は更新される。セレクタ6は、第1席のユーザの発話音声を第2席スピーカ4から出力するICCモードのとき、第2席スピーカ4から出力する発話音声Dpを第1可変フィルタ71の入力とし、非ICCモードのときは、第2席スピーカ4から出力される第2席オーディオソース2の出力音A2を第1可変フィルタ71の入力とする。発話音声Dpは、第1席マイク5の出力Mからキャンセル音Cの成分を除去して生成する。【選択図】図3
