Analysis of representative parameters grouping for the evaluation of voice signal automatic speaker recognition methods
Abstract
For any given set of coefficients representing a voice signal in a parametric space a speaker recognition method evaluation is proposed, based on the analysis of the element grouping derived from a sequential chart in which each element is characterized by its distance to the next element. In this chart groups are identified by low distance values. An iterative procedure is used to identify the central elements of each group. The experimental procedure used to test the grouping analysis is described.
