Book Description
"The Federal Bureau of Investigation (FBI) in March 1976 requested the National Academy of Sciences to undertake an evaluation of the use of sound spectrograms for identifying speakers from the sounds of their voices. The FBI observed that the preceding 15 years had brought about an expanding use of voice identification technology and that several kinds of related scientific experiments had been undertaken. Further, courts at various levels had ruled both for and against admitting evidence based on sound spectrograms, and persons who offered services in analyzing and testifying on speaker identification had established a professional organization of such practitioners"--Preface, page vii.

Book Description
Forensic Speaker Recognition: Law Enforcement and Counter-Terrorism is an anthology of the research findings of 35 speaker recognition experts from around the world. The volume provides a multidimensional view of the complex science involved in determining whether a suspect’s voice truly matches forensic speech samples, collected by law enforcement and counter-terrorism agencies, that are associated with the commission of a terrorist act or other crimes. While addressing such topics as the challenges of forensic case work, handling speech signal degradation, analyzing features of speaker recognition to optimize voice verification system performance, and designing voice applications that meet the practical needs of law enforcement and counter-terrorism agencies, this material all sounds a common theme: how the rigors of forensic utility are demanding new levels of excellence in all aspects of speaker recognition. The contributors are among the most eminent scientists in speech engineering and signal processing; and their work represents such diverse countries as Switzerland, Sweden, Italy, France, Japan, India and the United States. Forensic Speaker Recognition is a useful book for forensic speech scientists, speech signal processing experts, speech system developers, criminal prosecutors and counter-terrorism intelligence officers and agents.

Book Description
A voice is much more than just a string of words. Voices, unlike fingerprints, are inherently complex. They signal a great deal of information in addition to the intended message: the speakers' sex, for example, or their emotional state, or age. Although evidence from DNA analysis grabs the headlines, DNA can't talk. It can't be recorded planning,

Book Description
There are many reasons for writing a book; this one was conceived and devel oped mainly for two. First, a new area has emerged from within the forensic sciences-that of forensic phonetics. As with all new specialties, it is necessary to define it, identify its boundaries, justify its importance and compile a list of the elements it encompasses. This book attempts to outline these several rela tionships. Second, over the past decade I have become fascinated with forensics in general and the rapidly expanded subarea of forensic phonetics in particular. Admittedly, the latter field is one that is not as yet sufficiently appreciated-and much more needs to be known about its nature and extent. Yet, I have found it to be a most enjoyable area of study and my attempts to describe its domains were quite informative. It was especially interesting to struggle with the interfaces between forensic phonetics and related fields, and discover how they overlap. Only a few comments will be made about the book's contents here in the preface. For one thing, they are described in some detail in the first chapter.

Book Description
Why do so many people voluntarily consent to searches by have the police search their person or vehicle when they know that they are carrying contraband or evidence of illegal activity? Does everyone understand the Miranda warning? How well can people recognize a voice on tape? Can linguistic experts identify who wrote an anonymous threatening letter? Speaking of Crime answers these questions and examines the complex role of language within our criminal justice system. Lawrence M. Solan and Peter M. Tiersma compile numerous cases, ranging from the Lindbergh kidnapping to the impeachment trial of Bill Clinton to the JonBenét Ramsey case, that provide real-life examples of how language functions in arrests, investigations, interrogations, confessions, and trials. In a clear and accessible style, Solan and Tiersma show how recent advances in the study of language can aid in understanding how legal problems arise and how they might be solved. With compelling discussions current issues and controversies, this book is a provocative state-of-the-art survey that will be of enormous value to legal scholars and professionals throughout the criminal justice system.

Book Description
The Routledge Handbook of Phonetics provides a comprehensive and up-to-date compilation of research, history and techniques in phonetics. With contributions from 41 prominent authors from North America, Europe, Australia and Japan, and including over 130 figures to illustrate key points, this handbook covers all the most important areas in the field, including: • the history and scope of techniques used, including speech synthesis, vocal tract imaging techniques, and obtaining information on under-researched languages from language archives; • the physiological bases of speech and hearing, including auditory, articulatory, and neural explanations of hearing, speech, and language processes; • theories and models of speech perception and production related to the processing of consonants, vowels, prosody, tone, and intonation; • linguistic phonetics, with discussions of the phonetics-phonology interface, sound change, second language acquisition, sociophonetics, and second language teaching research; • applications and extensions, including phonetics and gender, clinical phonetics, and forensic phonetics. The Routledge Handbook of Phonetics will be indispensable reading for students and practitioners in the fields of speech, language, linguistics and hearing sciences.
