An engine sound generation device adapted to an electric vehicle includes an engine speed calculation unit which calculates the virtual engine speed based on the motor revolution speed, vehicle speed, and acceleration opening. The engine speed calculation unit calculates the virtual engine speed with reference to the vehicle-dependent engine speed memory on the condition that the virtual engine speed is deemed proportional to the vehicle speed. In addition, the engine speed calculation unit calculates the virtual engine speed with reference to the vehicle-nondependent engine speed memory on the condition that the virtual engine speed is not deemed proportional to the vehicle speed, thus generating the common engine sound matching the behavior of an engine in a prescribed event such as the startup of the electric vehicle and the semi-engagement of a clutch.
