Abstract —In this paper, the effect of features extracted onthe performance of speaker identification engine isinvestigated. Vector Quantization (VQ) is implemented andused as identification engine. Three type of speech features,Mel Frequency Cepstral Coefficients (MFCC), PerceptualLinear Predictive (PLP), and Relative Spectral Technique-Perceptual Linear Predictive (RASTA-PLP) are extractedand used for the classification problem. One word perspeaker is used within the train phase and the identificationrate is calculated for each feature extraction technique. Thecalculation is repeated using various word of differentspoken time, and the paper specifies the feature extractiontechnique that fits with the Vector Quantization (VQ)recognition engine.
