In order to prevent imposters f acquiring the access privilege of an authorize means of user authenticity are required information in general and one`s voice in part means; therefore a text-independent spea system was built for this concern. What chara is its implementation using LabVIEW on Nat CompactRIO, a control and acquisition sy reconfigurable I/O field-programmable gat technology. The Mel-Frequency Cepstral Coe technique is used for feature extraction from Quantization (VQ) technique based on the (LBG) algorithm for feature modeling, an distance classifier for the feature matching system identifies the user in runtime with high I.978-1-4673-0784-0/12/$31.00 ©2012 IEEE
