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.
Chapter 99: Forensic Speech Science

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 providing advice during pre-trial investigation.
As part of the Expert Evidence series this chapter is intended to be accessible to 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 speech science 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 forensic voice comparison. The 2018 edition has a heavier focus on automatic approaches.
The 2018 edition includes examples of forensic voice comparison based on real cases.
The 2018 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
Approaches to forensic voice comparison
Assessing the validity and reliability of forensic-comparison systems
“Morrison has a very nice writing style and I think he has phrased some of the fundamental matters in a way that is more clearly put than I have ever seen. I think he has done a masterly job.”

“It is very informative and at the same time easy to read – a rare combination. It’s a great book.”
