International, research-based expertise

Our expertise in linguistics, phonetics and acoustics is founded in academic and professional training as well as experience of thousands of forensic cases.  We continue to lead the field by engaging in practical and theoretical research, developing and pushing forward new approaches and technologies and driving quality standards.  Although we principally work for UK clients, JPFA experts have provided key evidence all over the world.  We are able to do this by recruiting and training consultants for forensic work across a range of languages and dialects.


All of our staff are experts in their field and aim to provide the highest level of service.  Our senior scientific staff are expert witnesses with many years’ experience in producing reports and presenting evidence from the witness box.
