"An Introduction to Forensic Phonetics and Forensic Linguistics is an authoritative and timely introduction to the use of linguistic science in the courtroom, providing the theoretical background and a practical discussion of the intricacies of speaker identification, earwitness accuracy, dialect variation, and other evidentiary issues. This book will be of value to experts in the fields of linguistics and phonetics, as a guide to solid forensic practices, and also to those present in the courtroom, as a caution against inferring greater reliability than an expert has claimed. Academics in these fields have been waiting for years for a book of this calibre to appear."Sandra Ferrari Disner, University of Southern California, USA"This is a well-designed textbook covering a wide range of topics in an engaging and accessible way, with interesting case-studies and plenty of exercises - all with suggested answers. It offers a valuable way to set beginners up to delve more deeply into the legal and scientific challenges of using language as forensic evidence. Highly recommended, not just for classes but for anyone with a general interest in forensic phonetics and linguistics."Prof. Helen Fraser - Director, Research Hub for Language in Forensic Evidence, University of Melbourne
