Based On The Wifi And Voicprint Recognition Technology Of Intelligent Attendance Management System Research

Although the current attendance management system has obvious progress compared to the previous sign in way, but as a result of or by cable data transmission, to layout and line butt is to complete the process of complex, and this way of working is not only time-consuming, waste of raw materials, and must be man-made to finish line management and data analysis. So can the attendance information remote wireless transmission and reception, to implement low cost, high efficiency, no fault of the attendance management system has become increasingly become people are urgently needed. System are studied in this paper is aimed at all such a requirement and design of simple efficient attendance system. The system is in the WiFi environment to sign in the collection to the check-in staff of voiceprint information sent to the backend server, with the background originally recorded voice print compare the libraries, thus draws the check-in staff attendance, attendance system.WiFi technology is the most popular standard of WLAN, conforming to the guidelines of IEEE802.11 wireless network, it is to use 2.4 G and 5 G two spectrum. WiFi is characterized by flexible, save a space, it is connected by means of wireless access, eliminating the past through the communication cable to connect the computer and network of tedious work. The structure of the network and terminal move more convenient.Voice print is the speaker’s voice pop chart, voiceprint recognition is speaker feature parameters are extracted from speech information and pattern matching method is used to calculate the process of recognition results, this paper use a voiceprint waveform of individual differences between personnel identification.This paper attendance management system based on Windows CE platform, SQL Server 2000 as the background database, combined with the star of the expansion and WiFi is easy to institutions, voiceprint recognition technology as the core technology, MFCC feature extraction personnel, advanced management theory of check on work attendance, realized the automation and scientific management of the process of check on work attendance.
