Forensic Evaluation of the Evidence Using Automatic Speaker Recognition Systems (2007)
Abstract / truncated to 115 words
This Thesis is focused on the use of automatic speaker recognition systems for forensic identification, in what is called forensic automatic speaker recognition. More generally, forensic identification aims at individualization, defined as the certainty of distinguishing an object or person from any other in a given population. This objective is followed by the analysis of the forensic evidence, understood as the comparison between two samples of material, such as glass, blood, speech, etc. An automatic speaker recognition system can be used in order to perform such comparison between some recovered speech material of questioned origin (e.g., an incriminating wire-tapping) and some control speech material coming from a suspect (e.g., recordings acquired in police facilities). However, ... toggle 6 keywordsforensic science – speaker recognition – likelihood ratio – kl-tnorm – empirical cross-entropy – evaluation of the evidence
