Currently, the local use of a personal computer is generally performed by performing a wake-up operation after booting or sleeping on the personal computer using a power key. Currently, a power key of a desktop computer is generally located on the front side or the upper side of a case, and when the computer case is placed in a closed or narrow space (for example, placed under a multimedia desk in a classroom), the power key is inconvenient to perform a wake-up operation after being turned on or dormant; the power key of the portable notebook computer is generally located on the C-side of the housing, when the portable notebook computer is used by externally connecting a screen in a closed state, the portable notebook computer needs to be opened specially to complete the operation of starting up or waking up after sleeping, and the operation is more inconvenient if the body of the portable notebook computer is placed in a closed or narrow space (for example, the portable notebook computer is hung on the back side of a display).

Although the computer supports other wake-up modes, it has certain disadvantages, and although computer motherboard manufacturers design peripheral power-on or wake-up functions for the computer, they can support the wake-up operation after the power-on or sleep of the computer by using the mouse/keyboard of the PS/2 interface and the network cable interface. However, the mouse and keyboard wake-up function is easy to be operated by mistake, and the user can only start or wake up the computer after approaching the computer, and then waits for the start-up process of the computer; the gateway wake-up function needs to be performed by another routing protocol transmitting device (e.g., another computer or a router).

The invention patent application with patent application number '2015101300027' discloses a voice wake-up system, a voice wake-up method and a mobile terminal, which provides a solution for waking up the mobile terminal by using voice, and a voice wake-up chip is used for analyzing and processing voice signals.

It also has certain disadvantages: the design does not have a universal wake-up interface, so that the design can only carry out wake-up operation on specific mobile equipment and cannot realize compatibility with a computer.

The invention relates to a multi-voice power-on control notebook computer with patent application number '2013104064671', which provides a design of a notebook computer based on voice wake-up.

It also has certain disadvantages: the awakening principle of the computer is changed by depending on the hardware of the computer circuit, and the awakening function cannot be integrated and transplanted in a scalable peripheral hardware mode, so that the computer circuit is not universal.

In summary, there is no effective solution for solving the technical problem of using a general peripheral device to wake up a computer by voice in the prior art.
