A vehicle sound generation device includes a sound control circuit that sets a plurality of frequencies according to a number of motor revolutions and sound pressures to be applied to the plurality of frequencies and generates a sound signal representing a synthetic sound including the sounds of the plurality of frequencies to which the set sound pressures have been applied, a speaker that outputs a sound according to the sound signal, generated by the sound control unit 12, and a travel situation estimation circuit that estimates a travel situation in which the driver accelerates or decelerates a vehicle at a rate below a predetermined threshold. The sound control circuit generates the sound signal representing only the single sound of the frequency in a range from 400 Hz to 900 Hz among the sounds of the plurality of frequencies when the travel situation is estimated.
