A terminal control method and device, a voice control device and a terminal are provided in the present invention. The method comprises: monitoring user voices including at least one voice fraction when it is detected that a main voice system of the terminal is closed; determining whether the voice fraction provided with a starting-up property appears, and if yes, sending out a starting-up signal used for starting up the main voice system of the terminal, and storing the voice fractions being monitored after the voice fraction provided with the starting-up property; and sending out the stored voice fractions after it is detected that the main voice system of the terminal is successfully started up. By the implementation of the present invention, when the main voice system of the terminal is closed, the voice fractions are detected to judge out whether it is required to start up the main voice system of the terminal. If it is required, the starting-up signal is sent out, meanwhile, after the starting-up signal
