Researchers at the University of Surrey have introduced a bespoke artificial intelligence system designed to bring much-needed clarity and accessibility to the UK’s highest court.
Their AI tool, designed for the language used in British Supreme Courtrooms, aims to make justice more accessible by creating more precise and searchable transcripts than regular commercial platforms.
The project, led by Professor Constantin Orăsan and his interdisciplinary team, builds on over 139 hours of hearing data and legal documentation.
The result is an AI speech recognition engine that effectively handles the complicated language and terms used in the legal field, providing much better transcription accuracy for important court cases.
What Is Unique About Surrey’s Courtroom AI?
Unlike one-size-fits-all commercial transcription services, Surrey’s AI was specifically trained on British judicial language, resulting in superior handling of legal terms, case references, and nuanced arguments.
This adaptation faithfully captures proceedings, often filled with technical wording, for the public record.
The system’s development involved close collaboration with legal experts, ensuring its ability to parse not only spoken words but also courtroom etiquette and subtle contextual cues that impact case understanding.

The Surrey team reduced Supreme Court transcription errors by up to 9% versus leading commercial tools.
How Does AI Improve Supreme Court Transcription Accuracy?
The University of Surrey’s solution demonstrated a reduction in transcription errors by up to 9% compared with leading commercial speech-to-text systems.
This improvement means fewer misunderstandings in legal records, which is critical when making judgments or reviewing precedents.
By minimizing inaccuracies, the tool helps safeguard against ambiguity and affords lawyers, journalists, and the public a clearer view of complex proceedings involving some of society’s most consequential decisions.
What Impact Could Tailored AI Have on Access to Justice?
Greater accuracy and immediate access to searchable transcripts empower not just legal professionals but also ordinary citizens and advocacy groups.
Better records increase the transparency of judicial decision-making, a principle fundamental to democratic societies.
The success of Surrey’s tool is already drawing interest from the UK Supreme Court and the National Archives, highlighting potential for national rollout as a model for modernizing public access to court proceedings.

How Are Video and Judgement Paragraphs Matched by AI?
Beyond transcription, the Surrey AI adds value by semantically matching written judgement paragraphs to their corresponding moments in video footage.
Legal scholars and the public can now directly locate the spoken arguments and evidence cited in key judicial decisions.
This feature not only boosts educational access but also allows real-time fact-checking and efficient review of lengthy case histories, helping reduce barriers to informed public debate about the law and its application.
Who Stands to Benefit from Justice System Innovation?
Journalists, legal professionals, and everyday court observers all profit from AI-powered clarity. By streamlining access to court dialogue and making verdicts more transparent, the technology promises advances in legal research, press reporting, and public trust.
Looking ahead, tailored AI systems like the University of Surrey’s may set the standard for digital justice, fostering greater transparency, civic engagement, and accountability in courts throughout the UK and beyond.
