The utility model discloses a voice simulation submarine. The submarine comprises a submarine body and a main control unit inside the submarine, wherein the main control unit is connected with a motion navigation system, a power system and a voice print system; the voice print system comprises a voice print memory and a voice amplifier; the voice print memory is used for storing feature voice print of motion states of a main submarine; and the voice amplifier is used for transmitting the feature voice print. The voice simulation submarine is low in cost and convenient to produce and apply in a large scale, and can simulate the feature voice print of a real submarine so as to draw away the detection and tracing of enemies to the main submarine, so that the invisibility and the battlefield survival rate of the main submarine are improved.
