Abstract

The invention relates to a telephone voiceprint entrance guard, and relates to an entrance guard apparatus. According to the invention, with the telephone voiceprint entrance guard, automatic access controlling voiceprint verification can be realized through a telephone, and jactitator identity can be easily identified. The entrance guard comprises a main controlling server, a telephone exchange, a voiceprint entrance guard controller, a network switch or a hub, a managing device, a bus, a telephone wire, a conduction-through twisted pair and a data trunk. The telephone exchange is connected to the main controlling server through the data trunk. The telephone exchange is connected to the voiceprint entrance guard controller through the telephone wire. The voiceprint entrance guard controller is connected to the network switch or the hub through the conduction-through twisted pair. The network switch or the hub is respectively connected to the main controlling server and the managing device through the bus.

Description

technical field [0001] The invention relates to an access control device, in particular to a telephone voiceprint access control system. Background technique [0002] The so-called voiceprint (Voiceprint) is the sound wave spectrum that carries speech information displayed by electroacoustic instruments. The human vocal system is composed of 45 "components" with different physiological structures, such as vocal cords, oral cavity, nasal cavity, tongue, teeth, lips, and lungs. Each "component" has different speech habits and methods. 100 different "postures" can be taken again, resulting in 45,100 kinds of timbres for people's voices, and everyone has unique voice characteristics. Modern scientific research shows that voiceprint is both specific and stable. After adulthood, the human voice can remain relatively stable for a long time. Experiments have proved that no matter whether the speaker deliberately imitates the voice and tone of others, or whispers softly, even if t...
