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
