Description

technical field [0001] The invention relates to the technical field of access control, in particular to an access control voiceprint recognition system and device. Background technique [0002] The so-called voiceprint is the sound wave spectrum that carries speech information displayed by electroacoustic instruments. The production of human language is a complex physiological and physical process between the human language center and the pronunciation device. The organs used by people when speaking, tongue, teeth The size and shape of the larynx, lungs, and nasal cavity vary greatly from person to person, so there are differences in the voiceprints of any two people. In some smart buildings, company confidential centers, R&D centers, scientific research places and other places, access control and other security devices need to be installed to ensure internal security. The existing magnetic card type access control devices are easy to be imitated and stolen, and the safety c...
