Control device, vehicle, sound emission device, and program

A control device according to an embodiment is provided with: a combination unit that combines a first sound signal acquired from a sound input device with a second sound signal acquired from a soundreproduction device, thereby generating a third sound signal; an output unit that outputs the second sound signal or the third sound signal to a sound emission unit; a notification control unit that outputs, to a notification unit, information for enabling the notification unit to provide a notification during at least a part of a time period in which the output unit is outputting the third soundsignal; and a registration unit that registers, in memory, information specifying the time period. 一个实施方式中的控制装置具有：合成部，其将从声音输入装置取得的第1声音信号和从声音播放装置取得的第2声音信号进行合成而生成第3声音信号；输出部，其将第2声音信号或者第3声音信号输出至放音部；通知控制部，其在输出部正在输出第3声音信号的状态的至少一部分的期间中，将用于使通知部进行通知的信息输出至该通知部；以及登记部，其将对期间进行确定的信息登记于存储器。
