<p>This hands-free device for a vehicle is provided with a suppression unit (9), a control unit (2), and an acquisition unit (8). In response to the input to a voice input unit (16) of a received voice outputted from a voice output unit (18), the suppression unit (9) suppresses an echo component included in a transmitted voice and/or a noise component included in the transmitted voice in accordance with the noise environment of a vehicle by acting according to a parameter. The control unit (2) sets a parameter for the suppression unit (9). The acquisition unit (8) acquires a vehicle state. When the control unit (2) determines, on the basis of the vehicle state acquired by the acquisition unit (8), that a change has occurred in the vehicle state, the control unit (2) sets for the suppression unit (9) a para meter for suppressing the echo component and/or the noise component after the change in the vehicle state occurred.</p> |
