A secondary authentication method suitable for voice command responses of smart devices

Abstract

The invention discloses a secondary authentication method suitable for voice command responses of intelligent equipment, comprising: voice monitoring, obtaining the monitored voice commands; pre-classifying types into control and non-control commands; recognizing the monitoring voice commands, Execute when it is recognized as a non-control sequence command, otherwise extract the feature threshold at a certain voice frequency and compare it with the pre-built voice sample information to determine whether the adder is a child: if yes, give an alarm and refuse to execute; Otherwise, compare the direction of the identified sound source with the direction of the sound source sample at the door to determine whether the applicator is in the direction of the door: if it is judged to be in a direction other than the door, execute the command, otherwise execute whether it is in the direction of the door Second confirmation: according to again The identified direction of the sound source is compared with the direction of the sound source sample. When it is judged to be at the door again, it is judged to be outside the door; otherwise, it is judged to be inside the door and the command is executed. The invention realizes the effective security control on the intelligent equipment.

Description

technical field [0001] The invention relates to a secondary authentication method suitable for voice command responses of intelligent equipment, and belongs to the technical field of security control. Background technique [0002] Compared with traditional speakers, smart speakers are an upgraded product of speakers in smart devices. The latter, as the terminal of the entire audio system, only converts audio power into corresponding sound energy and radiates it to the space; while smart speakers are considered to be the entrance of the Internet of Things era. In the Internet age, what users face is no longer a scattered combination of various home appliances and mobile devices, but an organic whole, and the audio system is no exception. Speakers with increasingly intelligent functions not only inherit the functions of traditional audio systems, but also serve as an important part of smart homes. You can also control smart home devices, such as opening smart door / window loc...
