About

I’m a first-year PhD student in the Phonetics Lab with a research background in forensic phonetics and sociophonetics. I completed an undergraduate MA in English Language and Literature at the University of Edinburgh and an MSc in Forensic Speech Science at the University of York. After this, I worked for four years in the Phonetics Lab here in Cambridge on a large, cross-institutional project called ‘Improving Voice Identification Procedures’ (IVIP) where I researched, presented and published on various aspects of earwitness identification evidence, specifically voice parades. Now I am taking on independent research, I’m curious about what makes a voice unique, memorable or distinctive, whether that’s in terms of acoustics, phonetics or listener perceptions.

Research Topic: The phonetic and perceptual underpinnings of voice distinctiveness and voice qualit

Research

I’m interested in the relationship between different measures of voice distinctiveness, specifically in the context of forensic phonetics. Previously, in my work on the IVIP project, we found that listeners perceive voices as sounding more different from one another when they have a more ‘common’ pitch value than when they have an unusual pitch value. My PhD extends this investigation to measures of voice quality to understand whether listeners perceive certain voice quality settings as making a voice sound more or less distinctive. I will investigate how this relates to extracted acoustic measures of distinctiveness. My project will also examine the effect of perceived voice distinctiveness on how well listeners can remember both the voice and the content of what was said. My research is funded by the AHRC as part of the Open-Oxford-Cambridge DTP, in collaboration with the National Crime Agency.
