Secondary authentication method applicable to voice command response of intelligent equipment

Abstract

The invention discloses a secondary authentication method applicable to voice command response of intelligent equipment, which comprises the following steps of: performing voice monitoring to obtain amonitored voice command; the types are divided into control type commands and non-control type commands in advance; identifying the monitored voice command, executing when the monitored voice commandis identified as a non-control column command, otherwise, extracting a characteristic threshold value at a certain voice frequency and comparing the characteristic threshold value with pre-constructed voice sample information to judge whether an adder is a child or not, and alarming and refusing to execute if the adder is the child; otherwise, comparing the identified sound source direction withthe direction of the sound source sample at the doorway; if it is judged that the applicator is located in the non-doorway direction, a command is executed, and if not, secondary confirmation in the doorway direction is executed: according to the sound source direction recognized again and the sound source sample direction, when it is judged that the applicator is located in the doorway again, itis judged that the applicator is located on the outer side of the doorway; otherwise, judging that the door is located inside the door and executing the command. According to the invention, effectivesafety control of the intelligent device is realized.

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...
