All our scientific staff and consultants are committed to advancing their field through high-quality research. Qualified to masters level or above, they regularly publish academic and professional papers and present their findings to international conferences.
We continue to forge the way ahead by collaborating with the University of York and other national and international partners. Staff at J P French Associates are collaborating with academics from the University of York on two major research projects after being awarded funding of £892,000 from the UK Arts and Humanities Research Council (AHRC) and £843,895 from the Economic and Social Research Council (ESRC). The project ‘Voice and Identity: source, filter, biometric’ will investigate the performance of a range of methods used in forensic speaker comparison; the project ‘The use and utility of localised speech forms in determining identity: forensic and sociophonetic perspectives’ explores how they respond to different regional accent varieties. J P French Associates staff also teach, and carry out and supervise student research, at the University of York’s department of Language and Linguistic Science, which specialises in forensic speech science. International partnerships include the Centre for Forensic Phonetics and Acoustics at the University of Zurich, where we are affiliated partners.
Some of our recent and current projects include:
- Voice and Identity: Source, Filter, Biometric – funding of £892,000 from the UK Arts and Humanities Research Council (AHRC) for a major three year project collaborating with academics from the University of York investigating the performance of a range of methods for speaker comparison on the same set of recordings. These will include methods from phonetics and linguistics, acoustics, and automatic speaker recognition.
- The use and utility of localised speech forms in determining identity: forensic and sociophonetic perspectives – funding of £843,895 from the UK Economic and Science Research Council (ESRC) for a major three year project collaborating with academics from the University of York investigating variation in long term acoustic measures within a database of recordings in a forensic context.
- Project investigating Panjabi heritage varieties of English in two cities, including data collection for use in a range of forensically relevant tests (doctoral research based at the Department of Language and Linguistic Science at the University of York.)
- Bayesian Biometrics for Forensics (BBfor2) – funded by the EC as a Marie-Curie ITN-project (FP7-PEOPLE-ITN-2008) – collaboration with the University of York and research and forensic institutions across Europe.
- Modelling features for forensic speaker comparison – British Academy/Leverhulme Trust funded project collaborating with academics from the University of York and forensic statisticians from the University of Edinburgh and the University of Glasgow.
- Investigation of relationships between voice quality and long term formant distributions within the DyViS Corpus – Collaboration with the University of York and the Phonetics Laboratory in the Department of Theoretical and Applied Linguistics, University of Cambridge
- A multi-methodological approach to the instrumental phonetic and perceptual study of rhotic sounds in varieties of English – University of Leeds
- Implementing the Electrical Network Frequency (ENF) system for use in practical forensic examinations
- ‘Formant measurement errors’ project (doctoral research based at the Department of Language and Linguistic Science at the University of York) and development of the ‘iCAbS’ bespoke formant tracking tool
- Project investigating the forensic application of systematic approaches to measuring voice quality (doctoral research based at the Department of Language and Linguistic Science at the University of York)
- Evaluation of automatic voice biometric systems for use in UK forensic speaker comparison casework
JPFA staff are centrally involved in the teaching and development of the world’s first postgraduate course and CPD course in forensic speech science in the Department of Language and Linguistic Science at the University of York, which has been running since 2007. Our staff also lecture and run courses on forensic speech and audio analysis at universities in the UK and abroad.
