Evaluation of Effectiveness of Different Methods in Speaker Recognition
Speaker's identification by voice is a type of biometric systems. Currently it is recent and rapidly developing science and technology with a lot of areas. Voice biometrics gives one of the worst results compared to other kinds of biometrics. The proposed new speaker's recognition method and a new system of features that consists of 36 components for that purpose. These components are formant and antiformant frequencies, their amplitudes, and various other combination parameters of spectral pairs (ratios of formant, their amplitudes and so on). Experiments with two speech databases showed that the proposed method outperformed the standard methods used for speaker identification - Gaussian mixture models using the mel scale cepstral coefficients (MFCC-GMM) and vector quantization (VQ) method.
