Expert Evidence is a major subscription based service available in paper and online and is a unique and well respected publication offering comprehensive coverage of over 75 expert witness fields. Expert Evidence is essential for preparation and case presentation by litigation lawyers (both civil and criminal), forensic specialists, and any expert drawn into investigations or hearings. The editors of the service are Dr Ian Freckelton SC, a leading member of the Victorian Bar and Hugh Selby, Associate Professor in the Legal Workshop, Law Faculty, of the Australian National University. Contributing experts are drawn from accredited laboratories, respected consultancy firms and highly regarded individual academics and practitioners.
As part of the Expert Evidence series the 100-page Forensic Voice Comparison chapter is aimed first at lawyers, judges, police officers, and potential jury members; however, it is hoped that this chapter will also be of interest to forensic scientists, phoneticians / speech scientists, speech-processing engineers, and students of all these disciplines. It introduces forensic voice comparison in a relatively non-technical way, assuming a reader who has no prior knowledge of the subject. The focus is on the understanding of concepts and the provision of basic knowledge.
