Abstract

The application discloses a voice attack detection method, device and network equipment. The method adopts a preset voice detection algorithm for the collected voice signal to be recognized, and after obtaining the signal strength of the voice signal to be recognized; if the signal strength is greater than the preset strength threshold, and the user terminal corresponding to the stored terminal identifier is disconnected from the network device state, it is determined that the voice signal to be recognized is an offensive voice signal, and the device ID currently in the wake-up state is matched with the stored device ID to be protected; if there is a successfully matched device ID, the corresponding The current network bandwidth of the home device is reduced by a preset bandwidth value to obtain a reduced network bandwidth; within the first preset time period, the reduced network bandwidth is maintained. The method improves the operation safety of the home equipment, and protects the home equipment by reducing the current network bandwidth, thereby further improving the use safety of the home equipment.

Description

Technical field [0001] The present application relates to the field of Internet security technology, in particular, to a method, apparatus, and network device of a voice attack. Background technique [0002] Voice identification technology has been widely used in a variety of home appliances, such as home appliances, smart speakers, etc., people interact through voice to control home equipment, such as home appliance power switch, parameter adjustment, etc. [0003] The speech recognition process for home devices contains device wake-up and command identification. The device wakes up, generally identifies the wake-up word of the voice signal in the voice signal, command identification, and the command word of the voice signal in the voice signal is used to identify the word word for the voice signal in the voice signal. the way. The online command identifies that the voice signal is sent to the cloud server, and the cloud server sends the identification result to the local proces...
