To provide a voice collection device capable of collecting voice at a higher SN ratio compared with a conventional manner by utilizing reflection voice.SOLUTION: A voice collection device is mounted on a vehicle. A vehicle is defined to include: a seat on which a passenger is seated; and a reflection structure body for reflecting voice uttered by a passenger seated on the seat. The voice collection device includes: a first microphone arranged at a position where direct voice being voice uttered by a passenger is easily collected; and a second microphone arranged at a position where reflection voice obtained by reflecting voice uttered by a passenger against the reflection structure body is easily collected.SELECTED DRAWING: Figure 2

    【課題】反射音も活用し、従来よりSN比の高い音声を集音できる集音装置を提供することを目的とする。【解決手段】集音装置は、乗り物に搭載される。集音装置は、乗り物は、搭乗者が着席する座席と、座席に着席した搭乗者が発した音を反射させる反射構造体とを含むものとし、搭乗者が発した音である直接音を集音しやすい位置に配置された第一マイクロホンと、搭乗者が発した音が反射構造体により反射した反射音を集音しやすい位置に配置された第二マイクロホンと、を含む。【選択図】図2
