Tutorial : The likelihood-ratio framework for the evaluation of forensic-comparison evidence Geoffrey Stewart Morrison 1,2 1 School of Language Studies, Australian National University, Canberra, Australia 2 School of Electrical Engineering & Telecommunications, University of New South Wales, Sydney, Australia This tutorial provides an introduction to the forensic comparison of audio recordings in the likelihood-ratio framework. Examples are drawn from audio recordings of human voices, but the principles and techniques can be applied to audio recordings of any source. The tutorial covers the topics essential for an understanding of the likelihood-ratio framework and its application to the forensic comparison of audio recordings including: What is a forensic likelihood ratio? Why is the likelihood-ratio framework the logically correct way to evaluate forensic evidence? How is a forensic likelihood ratio calculated? How is the validity and reliability of the likelihood-ratio output of a forensic-comparison system evaluated? What factors affect the validity and reliability of a forensic comparison system and how might validity and reliability be improved? |

Workshop: Overview of Digital Audio Authentication Chairman: Catalin Grigoras, Forensic Science Center, Romania This session will emphasize some of the latest developments in forensic authentication of digital recordings, like Electric Network Frequency (ENF) and lossy compression analysis. It will also present the most common source or errors, the nowadays technological limits and the need for quality assurance. The presentations will be interactive, in a lecture-discussion format with images, case studies and relevant research results.

Tutorial : SWGDE and Forensic Audio Standards Michael Piper1, 4, David Hallimore2, 4, and John Powell3, 4 1 U.S. Secret Service, Washington, D.C., USA 2 Houston Police Department, Houston, TX, USA 3 Los Angeles Sheriff’s Department, USA 4 Scientific Working Group for Digital Evidence, USA The Scientific Working Group on Digital Evidence (SWGDE) recently published a position paper on the U.S. National Research Council’s February 18, 2009 report to Congress entitled “Strengthening Forensic Science in the United States: A Path Forward” in which the Council set forth a broad overview of the state of forensic science in the United States along with several recommendations for improvement. An overview of The Report, SWGDE’s response, and its Audio Committee’s current projects will be presented. In each of the topics we intend to touch on (Forensic Audio Best Practices, minimum standards, accreditation/certification, training, ENF, etc.), there will be many points suitable for audience input and discussion. One of the key purposes of this presentation is to solicit input from the forensic audio community for the work we are undertaking at SWGDE.
