Abstract

The invention discloses a voice attack detection method, a voice attack detection device and network equipment. The method comprises the following steps: acquiring the signal intensity of a to-be-identified voice signal by adopting a preset voice detection algorithm on the acquired to-be-identified voice signal; if the signal strength is greater than a preset strength threshold value and the userterminal corresponding to the stored terminal identifier and the network equipment are in an off state, determining that the voice signal to be identified is an aggressive voice signal, and matching the equipment identifier which is in a wake-up state at present with the stored equipment identifier to be protected; if the successfully matched equipment identifier exists, reducing the current network bandwidth of the household equipment corresponding to the successfully matched equipment identifier by a preset bandwidth value to obtain a reduced network bandwidth; and maintaining the reduced network bandwidth within the first preset time period. According to the method, the operation safety of the household equipment is improved, the household equipment is protected by reducing the currentnetwork bandwidth, and the use safety of the household equipment is further improved.

Description

Technical field [0001] This application relates to the field of Internet of Things security technologies, and in particular to a detection method, device and network equipment for voice attacks. Background technique [0002] Voice recognition technology has been widely used in various home devices, such as home appliances, smart speakers, etc. Humans interact with home devices through voice to control the behavior of home devices, such as power switches and parameter adjustments of home appliances. [0003] The voice recognition process for home devices includes device wake-up and command recognition. Device wake-up is generally local recognition of the wake-up words of the voice signal in the voice signal, command recognition, there are two types of local recognition of the command word of the voice signal in the voice signal and the cloud server recognition of the command word of the voice signal in the voice signal the way. Among them, online command recognition is a process i...
