FORENSIC COMMUNICATION ASSOCIATES
	"Offering expert services for 20+ years"

As the current number of court cases involving tape-recorded evidence, the authenticity of tape recordings, speech decoding from tape recordings, stress in voice analysis, and speaker identification continues to grow, so does the number of problems and issues associated with forensic phonetics.  New technological developments and techniques and novel approaches are needed to address the challenges presented by the rapid growth of this area Of the forensic sciences. In The Acoustics of Crime, author Harry- Hollien addresses all of the above situations, creating an overview of the ever-expanding field of forensic phonetics.  The book, based on Hollien's thirty plus years of personal experience and relevant scientific principles and experimental results, reviews various elementary issues involved including the nature of sound, the basics of speech and how it is produced, and the elements of human hearing.  The sources of forensic problems on all kinds of tape recordings and what to do about them, the identification of speakers from their voice alone, and the general problem of detecting stress in humans are fully examined.  Through illustrative examples of actual cases that Hollien has been involved with, readers will learn what can and cannot be accomplished by forensic phonetics specialists.
