Smart Card Based Speech Recognition System- The aim of the project is to verify the identity of the speaker using his voice as a metric. The system is trained using five utterances of a voice password. The system extracts features from the user’s voice and stores his voice profile in his smart card along with his personal information. After that when the user needs to verify the identity, he inserts the smart card in to the system and records the voice password. The system compares the voice with the one stored in the smart card. If both voice profile match with each other, the user is accepted otherwise the user is rejected. The voice profile of the user is stored in the smart card in form of MFCC coefficients. The system uses a minimum Euclidian distance measurement algorithm to compare the two voice profiles. We have developed a smart card reader-writer to interface smart card with the system. Finally we tested the system performance by testing it on 2 users.
