Introduction
Sophie Wood now works for the Dictionaries Department at Oxford University Press. Sophie holds undergraduate (BA English Language and Linguistic Science) and postgraduate (MSc Forensic Speech Science) degrees from the University of York. She researched filled pauses as a discriminatory parameter for forensic speaker comparison for her MSc dissertation and presented at the 2014 IAFPA conference. Sophie also worked on the project "Perceptual adaptation to regional accents as a new lens on the puzzle of spoken word recognition".

We assess the potential improvement in the performance of MFCC-based automatic speaker recognition (ASR) systems with the inclusion of linguistic-phonetic information. Likelihood ratios were computed using MFCCs and the formant trajectories and durations of the hesitation marker um, extracted from recordings of male standard southern British Englis...
This study investigates the evidential value of filled pauses (FPs, i.e. um, uh) as variables in forensic voice comparison. FPs for 60 young male speakers of standard southern British English were analysed. The following acoustic properties were analysed: midpoint frequencies of the first three formants in the vocalic portion; 'dynamic' characteris...

To probe how episodic and abstract processes contribute to flexible perception of phonetically variable speech, we evaluated Australian (Aus) listeners' perception of Aus-accented vowels versus those of an unfamiliar accent: Newcastle UK (Ncl). Aus listeners first heard a round-robin story told by multiple talkers of Aus or Ncl, then categorized mu...
We evaluated how Australian listeners perceive consonants spoken in two unfamiliar accents of English (Cockney, Yorkshire) and how consonant perception is influenced by short-term exposure to those accents. Results indicate that Australians misperceive some consonants from these accents and that short-term pre-exposure to them actually leads to fur...
