First an introduction proposes a modular scheme of the training and test phases of a speaker verification system. Then the most commonly speech parameterization used in speaker verification namely cepstral analysis is detailed. Gaussian mixture modeling which is the speaker modeling technique used in most systems is then explained. A few speaker modeling alternatives namely neural networks and support vector machines are mentioned. Normalization of scores is then explained as this is a very important step to deal with real-world data. The evaluation of a speaker verification system is then detailed and the detection error trade-off DET curve is explained. Several extensions of speaker verification are then enumerated including speaker tracking and segmentation by speakers. .
