Mission
DDL STATEMENT
As a Specialist Consultancy & Training firm, we are dedicated to uncovering the truth hidden within language. Our mission is simple but transformative:
'To give organisations and individuals clarity, confidence, and control by revealing what words disclose.'
For the first time, we are enabling UK businesses to employ U.S. Intelligence Grade methods to protect their organisations, uncover hidden risk and see the truth behind every word.
Get to Know Us
FSLA-1.0 SYSTEM ARCHITECTURE
DDL has introduced U.S. Intelligence-Grade Linguistic Deception Detection to the UK.
For decades, techniques like Forensic Analysis have aided investigations in the FBI, CIA, and U.S. Defence. Our Forensic Statement Linguistic Analysis (FSLA) model combines this approach plus peer-reviewed research, authorship analysis, veracity assessment, discourse analysis, phonetics and even metadata for a comprehensive intelligence approach.
What is FSLA?
DDL DEFINITION
'Forensic Statement Linguistic Analysis (FSLA) is the scientific examination of written or spoken language to uncover meaning, intent, credibility, authorship & risk in high‑stakes situations.'
At DDL, we use FSLA because its trusted methodology can save Legal, Intelligence and Corporate Risk teams significant amounts of time and money. We are also exploring how it can be used to detect Fraud.

Why we Matter to UK Organisations?
DDL DNA
By using FSLA, UK leaders gain a competitive and operational advantage that no other organisation in the country currently has access to.
Our FSLA methodology analyses the structural DNA of language, isolating micro-shifts in syntax and verb tenses to provide empirical evidence, acting as linguistic 'night-vision' to reveal hidden insights.
Until now, this capability has never been commercially available in the UK. Much of the methodology was restricted to intelligence agencies, federal law-enforcement units, military interrogators, and specialist investigators.
