Where this applies
United Kingdom. Researchers building a transcription tool for the justice sector with an industrial partner say legal transcription is largely met by human transcribers, that the word error rate of a generic cloud speech recogniser remains relatively high on British court rooms because of long hearings, multiple speakers and unusual vocabulary, and that their domain-adapted model outperforms AWS and Whisper with a 9% and 8% word-error improvement; their gold-standard transcripts were made by legal professionals post-editing machine output. It is a workshop preprint with a commercial partner.
What this means
Courtroom audio is hard for generic speech recognition; even the improved systems start from drafts that legal professionals correct.
What it does not yet show
A preprint with a commercial partner and 2022-era models; newer systems may do better.
What you can check
Open the arXiv paper "Better Transcription of UK Supreme Court Hearings" (2211.17094) and find "remains relatively high".
Does it change the assessment?
No — and this stage does not move it either. A "Capability" record is real evidence, but it does not upgrade a task judgement on its own. The 1 linked judgement above stand where they were.
