Abstract (Summary of the Work)

We have concentrated on the speaker identification part of the speaker recognition problem. Here, we have made a study which involves the classifi- cation and identification of the speakers using the Gaussian mixture models (GMM) and the mel frequency cepstral coefficients (MFCC). Due to its re- ported superior performance, especially under adverse conditions, MFCC is becoming an increasingly popular choice as feature extraction front end to spoken language systems. The individual Gaussian components of a GMM are shown to represent some general speaker-dependent spectral shapes that are effective for modelling speaker identity. A complete experimental evaluation is conducted on two sets of data of 7 speakers and 21 speakers. The GMM attains 100% accuracy on the 7 speaker data and 97.3% on the 21 speaker data using clean speech utterances.
