Module aims

This course provides an introduction to the practical, ethical, and legal principles of forensic speech analysis in criminal investigations. Through auditory and instrumental analysis, we will investigate the phonetic parameters which can be useful in the process of identifying an individual speaker. We will discuss and replicate phonetic analysis which has been performed in criminal cases. We will also explore the performance of lay listeners in speaker identification, discussing the problems involved in eliciting and using 'earwitness' evidence in court.
