Description

technical field [0001] The invention relates to an access control system, in particular to a text-prompted 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. Another 100 different "poses" can be taken, resulting in a unique vocal signature for each individual. 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 the imitation is vivid, the voiceprint is al...
