Abstract

Abstract: Forensic voice comparison is quite challenging because the quality of speech recordings in casework is often poor and there is often mismatch between the recording conditions of the known- and questioned-speaker recordings. Further, the field of forensic voice comparison is characterized by a large diversity of methods, procedures and evaluation of comparison results. The present paper aims to provide a concise review of various comparison methods and assessment of comparison results. The need of an extensive amount of experimental studies and statistical evaluation on a large database is highlighted to use the likelihoodratio framework for reporting conclusions that has been now firmly established as a theoretical framework for any forensic discipline.
