Using speech and audio as evidence

The course is intended for those who want to learn more about how speech and audio are analysed for evidential purposes and this area of forensic science. A range of topics will be covered and sessions will include a mix of practical tasks and theoretical content. 

The first day will provide an overview of different types of speech and audio evidence and what is and isn’t possible. We will discuss important practical considerations when collecting material for evidential purposes. Throughout both days, attendees will develop an understanding about the range of methods applied in forensic speaker comparison - the most common type of voice evidence - including the combined auditory-acoustic method, and automatic speaker recognition (including access to VOCALISE speaker recognition software). Sessions will cover how experts arrive at conclusions and the place of speech and audio evidence in the court. Consideration will be made of the role of regulation and accreditation in forensic speech science and the implications of this.  

Note: This course is not intended to provide attendees with the skills and knowledge to carry out forensic speech and audio analysis. It is intended to raise awareness and give an understanding of how speech and audio can be used as evidence.

Vincent Hughes

Vincent's research interests lie in forensic speech science, phonetics, phonology, sociophonetics and sociolinguistics. His current research focuses on understanding the bases and limitations of individual speaker characterisation and the relative contribution of acoustic, auditory and biological information. He is also interested in the application of the numerical likelihood ratio framework to the evaluation of speech evidence in forensic voice comparison cases.

Jessica is a lecturer in the Department of Language and Linguistic Science at the University of York. Her primary research interests are in forensic speech science and sociophonetics. Jessica is interested in research which leads directly to improvements in forensic practice, particularly methodological developments and the combination of auditory, acoustic and automatic techniques. She previously worked as a forensic consultant at J P French Associates where she carried out speaker comparison and transcription casework.
