The PI
Magazine Bookstore is
proud to offer Forensic Aspects of Speech Patterns to
investigators. Speech patterns play an increasingly important
role in criminal investigation and litigation. Historically,
a suspect's speech has always provided cues about truthfulness,
mental and emotional states, and levels of intoxication. Accent
and dialect have also given information about an individual's
homeland.
However, since the tragic events of September 11, 2001, speech
patterns have taken on more important forensic roles. Voice prints
are being used to verify the authenticity of terrorists' taped
messages, and psychological stress evaluation (fluctuations in
laryngeal micro-tremors) of their speech provides information
about truthfulness and deception. Voice psychological stress
evaluation also can be used to provide information about general
levels of anxiety and tension of speakers in airports and other
ports of entry. Accent and dialect can be used in speaker profiling
as one method of determining whether a suspect is traveling from
a hostile country. Finally, speech patterns provide important
screening information about intoxication giving law enforcement
officers probable cause for detainment and further investigation.
Forensic Aspects of Speech Patterns: Voice Prints, Speaker Profiling,
Lie and Intoxication Detection provides lawyers, judges, and
law enforcement personnel with basic information when using speech
patterns as investigative and litigating tools. The chapters
in this book address the basics of human communication, phonetics,
anatomy and physiology, speech acoustics, relevant disorders,
and the forensic applications.
Topics include:
• An overview of human communication
• Speech Analysis explained
• Subjective and objective methods of voice identification
• Automatic voice identification
• Speaker profiling Race, Culture, Ethnicity and Linguistic Behavior
• Accents and dialects
• Linguistic difference based on socioeconomic status
• Lie Detection from voice stress analysis
• Psychology of the voice
• Speech patterns
• Intoxication detection
• Diseases and disorders affecting the voice
