A speech remote control device includes a speech input unit, a speech identification unit, a motion setting unit, a transmit unit and a receiving unit. The speech input unit converts a received speech command into a speech signal. The speech identification unit receives the speech signal, and transmits an encoded message. The motion setting unit receives and decodes the encoded message to generate a combination message with a proceeding control command and a turning control command, or comprising a series of sub-combination messages. The transmitting unit receives and transmits the combination message to the receiving unit provided on the remote control car. The remote control car is driven by the receiving unit to automatically change direction or make more than one turn during proceeding. Thus, only one speech command controls the remote control car to simultaneously proceed and make a turn without sending any additional command for changing direction.
