Workshop 1: Let's talk about Bayes!
Hosts: Tina Cambier-Langeveld and Christin Kirchhübel
Abstract: Within the forensic field and across many disciplines there has been a shift towards using a Bayesian framework. In this workshop we discuss why that is so. The workshop includes basic training in the principles of Bayes, as well as a discussion on its suitability for non-numerical, experience-based assessments of the evidence as in auditory-acoustic speaker comparisons. We also share experiences with the use of a Bayesian conclusion format in forensic speaker comparison casework, including how it is received and understood by courts (at least in NL and UK jurisdictions).
The workshop is suitable for everyone with an interest in the Bayesian framework. No familiarity with the Bayesian framework is required.
Workshop 2: Doing Casework.
Hosts: Volker Dellwo and Herbert Masthoff
Abstract: This workshop is specifically tailored to participants interested in gaining deeper insights into the practical aspects of voice analysis and speaker comparison within the field of forensic phonetics. We will analyze conversational speech samples relevant for forensic cases with auditory and acoustic methods. Participants should bring headphones and equipment for download and playback.
Workshop 3: Breaking the chain: exploring limits of interpreting audio evidence.
Hosts: Philip Harrison and Amelia Gully
Abstract: In this workshop, we will explore the elements of the recording chain which are important in forensic casework. We will consider how different sound sources, recording conditions and devices affect the final evidential recording, and how interactions between all of these elements need to be considered when interpreting forensic recordings. We will consider sound source identification and other more common forensic examinations, and exemplify how erroneous conclusions can be drawn if all the relevant factors are not properly taken into account. Using example recordings and interactive demonstrations, we will highlight issues encountered in real cases and discuss the implications for the auditory interpretation of evidential recordings.
