Course Leader: FoSS Team - Forensic Speech Science at the University of York
This two hour online workshop will explore frameworks for evaluating the strength of forensic comparison evidence, with a focus on forensic speaker comparison. Specifically, we will provide an overview of the likelihood ratio framework and discuss how this approach effectively separates the role of forensic analyst and trier-of-fact in the context of criminal justice. We will also discuss data-driven approaches to computing likelihood ratios, using case-specific data and examples from both phonetic analysis and automatic speaker recognition systems. In addition, this workshop will outline challenges associated with the effective and appropriate evaluation of the strength of forensic speaker comparison evidence and highlight potential approaches to addressing these challenges.
The course will provide participants with:
- Increased understanding of the likelihood ratio framework
- Awareness of propositions relevant to forensic comparison, and the effect these propositions have on the resulting strength of evidence
- Knowledge of how to compute a likelihood ratio with relevant data
