Abstract

At present, Speaker recognition systems are being widely used in speaker detection, authentication and authorization to perform secure transactions in various personal, commercial and industrial applications. As speaker recognition in noisy environments is becoming increasingly difficult, a novel system is developed using MFCC and Vector Quantization. The training data is collected from 15 native speakers. LMS, NLMS and RLS adaptive filters are used to reduce the noise in the speech signal. The performance of all the speaker recognition systems is rated by calculating the Equal Error Rate (ERR) and Euclidian distance.
