AI accuracy & hallucination report

Every Hanah region is graded by the same harness, the same ground-truth corpus, and the same published methodology: Word Error Rate against verbatim transcripts, plus an LLM jury panel grading coverage and hallucination. Each region runs its own speech and language stack, so each is graded — and published — separately. The headline numbers below render from the exact data each regional report publishes; open a region for the per-recording transcripts, generated documents, and per-juror verdicts behind them.
