Three simple speaker verification tech- niques based on vector quantization, sphericity mod- els and dynamic time warping, respectively, are de- veloped and tested using the same experimental pro- tocol. Two types of feature vectors, the linear pre- diction derived cepstral coefficients and the mel- frequency cepstral coefficients are considered. The efficiency of the combination of the type of acoustic analysis and the verification technique is quantita- tively measured through the achieved equal error rate.
