The network control center is connected with an external network, and in a home, a router generally plays the role of the network control center. The network control hub collects the operating conditions of all the access devices.
The network control center can preset a voice analysis table and a device mapping table to determine the terminal device and the corresponding wireless extender to which the voice is appointed. After receiving the voice command, the network control center firstly determines the terminal equipment to which the voice command is directed according to a preset voice analysis table, and then determines the wireless extender corresponding to the terminal equipment according to an equipment mapping table after determining the terminal equipment to which the voice command is directed through the voice analysis table.
Optionally, the voice parsing table determines the terminal device corresponding to the voice instruction according to the fact that the voice instruction includes a keyword related to the terminal device, and in general, when the user issues the voice instruction, the user will include the keyword of the terminal device to be controlled, for example, the user issues the voice instruction as follows: and when the television is turned on, capturing the keyword television in the voice analysis table, and determining that the terminal equipment to which the voice instruction is directed is the television. The terminal equipment which the user wants to control can be quickly and accurately determined according to the voice instruction by utilizing the voice analysis table.
