Abstract

The invention provides an intelligent access control recognition system based on speech recognition, which includes a first sound sensor, a second sound sensor, a third sound sensor, a feature extraction unit, a signal processing circuit, a signal processing unit, a signal generation unit, a signal A receiving unit, an intelligent access control processor, an image acquisition unit, an image comparison unit, and an access control controller, wherein the first sound sensor can realize the recognition and distinction of speech feature quantities, and then use the second sound sensor or the third sound sensor Receive the voice signal of the user, and then process the voice signal through their respective signal processing methods, which can greatly improve the accuracy of voice recognition.

Description

technical field [0001] The invention relates to the field of intelligent access control, in particular to an intelligent access control identification system based on speech recognition. Background technique [0002] RFID (Radio Frequency Identification), that is, radio frequency identification, is a short-range wireless communication technology. Compared with other short-range wireless communication technologies such as WLAN, Bluetooth, infrared, ZIGBEE, and UWB, the biggest difference is that RFID is a passive working mode. RFID technology adopts large-scale integrated circuit computing, electronic identification, computer communication and other technologies, and realizes non-contact identification and data information exchange of carriers through readers and RFID tags installed on carriers. Fast, large data capacity, long service life, label data can be dynamically changed, etc., so it has better security, dynamic real-time communication and other advantages than barcod...
