Evaluation of Speaker Recognition System Using Different Distance Metrics

Authors(3) :-Sukhvinder Kaur, Monica, J. S. Sohal

In today's world scenario, speaker recognition system is very popular in voice verification for identity and access control to services. In this paper, speaker identification and verification is done with the help of feature extraction and different matching algorithms. We have introduced a new approach for speaker recognition. In this system, speech signals are firstly framed and then these signals are compressed using DWT for noise reduction and better sampling frequency. Furthermore, features of compressed signal are extracted with the help of Mel frequency Cepstral Coefficients (MFCC) and nonlinear energy operator (NEO). These features are further used for identification and verification of speaker’s voice. The distance metrics incorporated are Delta Bayesian Information Criteria (delta BIC), Kullback-Leibler Distance Metric (KL2), and T-Test metric. At the end, results are evaluated with Detection Error Tradeoff (DET) curve and Receiver Operator Characteristics (ROC) curve by finding the area under curve (AUC). The best result is shown by T-Test metric with MFCC feature.
