What is FSLA?
DDL DEFINITION
'Forensic Statement Linguistic Analysis (FSLA) is our umbrella term to describe the scientific examination of written or spoken language to uncover meaning, intent, credibility, authorship & risk in high‑stakes situations.' DDL
We combined the widely researched and trusted principles of Linguistic Analysis with Forensic Statement Analysis because together the methodology works to save clients time & money.
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.
This 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.
