In this embodiment, taking a voice air conditioner as an example, when a user controls the air conditioner through voice, a voice instruction needs to be sent to the air conditioner, when the air conditioner receives the semantic instruction, the semantic instruction is analyzed and at least one keyword is obtained, then a corresponding node is searched for by traversing a semantic network, where the semantic network is composed of a plurality of instantiated nodes, and the nodes are established based on the function information of the smart home device, for example: the first voice command is: and opening the air conditioner, wherein the keyword is open, a node corresponding to the keyword 'open' is queried from the semantic network as 'control _ on', the function corresponding to the node is open, a control instruction is generated according to the node, and the air conditioner is controlled to execute the operation of opening according to the control instruction.
The following embodiment describes a method for establishing a semantic network in detail, and fig. 2 is a flowchart of a voice control method according to another embodiment of the present application. As shown in fig. 2, before traversing the semantic network to determine the node corresponding to the keyword, the method further includes the following steps:

Such as: the first voice instruction may be: the intelligent lamp is turned on, the second voice instruction can be used as a supplementary instruction of the first voice instruction, namely, a user thinks that the brightness of the lighting mode corresponding to the first voice instruction is too low, the user can send the second voice instruction to the intelligent lamp within a preset time threshold range, and the sub-node of the brightness can be inquired when the node is turned on, and if the lamp is turned on a little, the control is realized through the sub-node of the brightness; as another example, the first speech signal may be: turning on the air conditioner, the second voice signal may be: the temperature is adjusted to be lower and the wind speed is adjusted to be higher.
In another embodiment of the application, when a user switches a working mode of the smart home device, for example, switches an illumination mode of an illumination lamp or an operation mode of an air conditioner, the user receives a third voice instruction, analyzes the third voice instruction, extracts at least one third keyword from the third voice instruction, determines a second target sub-node corresponding to the third keyword based on a semantic network, generates a control instruction according to the second target sub-node, and controls a current mode of the smart home device to be changed into a mode corresponding to the third voice instruction according to the control instruction.
