Our Mission

“To provide the highest quality forensic evidence concerning speech and audio recordings; by maintaining a culture which promotes critical and detailed analysis, clear and effective communication, and constant improvement at the level of the individual and the organisation, and which promotes the values of impartiality, integrity, transparency and confidentiality. By following these principles, we aim to be the leading provider of forensic speech and audio evidence in the UK and worldwide.

Our Values


We maintain a strong focus on our duties as experts within the justice system.


We never compromise on our impartiality; we work for both prosecution and defence.


We subject each case to a robust, independent checking process.


We meet deadlines and work cost-effectively.


We ensure the security, confidentiality and continuity of material in our care.


We recruit highly qualified staff and invest in their development.


We monitor and improve how we operate to maintain high-quality standards.


We continue to develop through partnership with academic bodies and professional groups.


Providing an excellent service to our clients is key to our operation at J P French Associates. From first enquiry to court appearance, we ensure a proactive and consistent line of contact through our dedicated practice administrator and a case manager, so our clients are assured that their case is being progressed within their timeline, meeting their critical deadlines. Our experts are always willing to give advice on the right forensic strategy for your case.


We operate in accordance with a Quality Management System which meets the standards set by the Forensic Science Regulator, and other bodies such as ISO and ENFSI. We are aiming to gain accreditation to these standards.

We take pride in the quality of our work and operate a universal quality control and peer-review process.  The work of every expert is checked by a second member of scientific staff.  No work leaves the laboratory without these checks and reviews.


We ensure all our staff are highly trained and competent in their subject areas by hiring highly qualified specialists, and investing in their ongoing learning and development.

Our analyses are underpinned by state-of-the-science technology and software, many of which we have exclusive access to because they have been tailored by our experts for forensic purposes.
