This paper presents a probabilistic approach for representing a speaker using the anchor modelling technique and discusses the relation between this new approach and the deterministic approach. In the first part, the technique of anchor modelling is presented. Then the new approach, which modelizes the various utterances of a speaker by a normal distribution in the anchor models space, is presented. A study of the relation between the two approaches (deterministic and probabilistic) leads to the definition of a combined approach. All these approaches are evaluated on the NIST 2000 database and results show improved performance of the combined approach over the deterministic and the probabilistic one.
