+# MultiMed Hard — Medical ASR Benchmark
+
+Entity-aware medical ASR benchmark — 50 hard rows from medical lectures and interviews.
+
+## Source
+
+Derived from [leduckhai/MultiMed](https://huggingface.co/datasets/leduckhai/MultiMed) EN test split (4,751 rows, MIT license). YouTube medical channels — lectures, interviews, podcasts, documentaries. Transcripts are human-reviewed.
+
+## Preparation
+
+1. Filter: audio ≥ 2s, ≤ 29s, text ≥ 20 chars
+2. Casing filter: drop all-caps / all-lowercase rows
+3. Whisper CER filter: drop rows with whisper-large-v3 CER > 10% (bad GT alignment)
+4. Gemini Flash entity tagging (6 medical categories)
+5. Keep rows with ≥ 1 entity (entity text ≥ 5 chars)
+6. 3-model difficulty filter (whisper-large-v3, canary-1b-v2, Voxtral-Mini) with whisper-english normalization
+7. Exclude median entity CER > 0.9
+8. LLM validation (Gemini Flash): drop non-medical content, generic entities, GT typos
+9. Top-50 by median entity CER
+
+## Entity categories
+
+- **drug** — drug or medication names (brand or INN)
+- **condition** — diagnoses, diseases, syndromes, disorders
+- **procedure** — surgical, diagnostic, or therapeutic procedures
+- **anatomy** — anatomical structures, organs, body regions
+- **biomarker** — lab tests, biomarkers, genes, proteins, molecular markers
+- **organisation** — hospitals, regulatory bodies, pharmaceutical companies
+
+
+## Columns
+
+- `audio` — 16kHz WAV
+- `text` — ground truth transcript (human-reviewed)
+- `entities` — JSON array of tagged medical entities with `text`, `category`, `char_start`, `char_end`
+- `difficulty_rank` — 1 = hardest
+- `median_entity_cer` — median entity CER across 3 difficulty-filter models
+
