EKA Hard — Medical ASR Benchmark

Entity-aware medical ASR benchmark — 50 hard rows from Indian-accented clinical speech.

Prepared by Trelis Research. Watch more on Youtube or inquire about our custom voice AI (ASR/TTS) services here.

Source

Derived from ekacare/eka-medical-asr-evaluation-dataset (3,619 EN rows, MIT license). Real clinical speech from 57 speakers across 4 Indian medical colleges, 16kHz mono.

Preparation

1. Filter: audio ≥ 2s, text ≥ 20 chars
2. Gemini Flash entity tagging (6 medical categories)
3. Keep rows with ≥ 1 entity
4. 3-model difficulty filter (whisper-large-v3, canary-1b-v2, Voxtral-Mini) with whisper-english normalization
5. 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-annotated)
• 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
