This book introduces recent research on "profiling" humans from their voice, which seeks to deduce and describe the speaker's entire persona and their surroundings from voice evidence. It covers several key aspects of this technology in its current nascent state, describing how the human voice can be a powerful indicator of identity -- how, in some ways, voice is more potent and valuable than DNA and fingerprints as forensic evidence, since it not only carries information about the speaker, but also about their current state and their surroundings at the time of speaking. It provides a comprehensive review of prior advances made in multiple fields that now contribute to its foundations. It describes how artificial intelligence now enables mechanisms of discovery that were not possible before, in this context, propelling the field forward in unprecedented ways. It also touches upon related and relevant challenges posed by voice disguise and information hiding in audio signals. The book acts as a good resource for professional forensic labs, security and law enforcement agencies. This technology, as of now, has helped investigate hundreds of instances of voice recordings in federal crimes.weiterlesen
