Forensic Speech Science
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.
Expert Evidence: 75 Expert Areas is comprehensively drafted to fully prepare the everyday litigator for their legal matter, ensuring for example that your pre-trial conferences run smoothly, the questions you put to your experts are the right questions, your time spent in hearings is productive and ultimately that your client feels they are getting the best advice possible.

- Forensic voice comparison is the comparison of one or more audio recordings of the voice of a known speaker with an audio recording of the voice of a speaker of questioned identity for the purpose of presenting expert testimony in court or during pre-trial investigation.
- As part of the Expert Evidence series this 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 2010 edition had a heavy focus on acoustic-phonetic statistical approaches to foresnic voice comparison. The 2017 edition has a heavier focus on automatic approaches.
- The 2017 edition includes examples of forensic voice comparison based on real cases.
- The 2017 edition also includes expended coverage of other branches of forensic speech science.
- Topics covered include:
- The likelihood ratio framework for the evaluation of forensic evidence
- Approches to forensic voice comparison
- Assessing the validity and reliability of forensic-comparison systems
- Speaker identification by laypeople
- Disputed utterance analysis
- The authors:
