Forensic speaker recognition

Definition

Forensic speaker recognition is the process of determining if a specific individual (suspected speaker) is the source of a questioned voice recording (trace). The forensic application of speaker recognition technology is one of the most controversial issues within the wide community of researchers, experts, and police workers. This is mainly due to the fact that very different methods are applied in this area by phoneticians, engineers, lawyers, psychologists, and investigators. The approaches commonly used for speaker recognition by forensic experts include the aural-perceptual, the auditory-instrumental, and the automatic methods. The forensic expert’s role is to testify to the worth of the evidence by using, if possible a quantitative measure of this worth. It is up to other people (the judge and/or the jury) to use this information as an aid to their deliberations and decision.
