Eka Medical ASR Evaluation Dataset

Dataset Overview and Sourcing

The Eka Medical ASR Evaluation Dataset enables comprehensive evaluation of automatic speech recognition systems designed to transcribe medical speech into accurate text—a fundamental component of any medical scribe system. This dataset captures the unique challenges of processing medical terminology, particularly branded drugs, which is specific to the Indian context. The dataset comprises over 3,900+ curated audio recordings featuring medical terminology delivered in various speaking styles, including isolated medical entities, narrated medical sentences, and impromptu medical conversation. The dataset includes approximately 3,600 English recordings and 320 Hindi recordings. We intend to keep improving and growing this dataset for different languages and scenarios.
For details read this blog.

Data Collection and Quality Assurance

All audio recordings capture natural speech patterns, ensuring realistic evaluation scenarios. A significant portion of the dataset originates from EkaCare's internal team members through narrated medical text sessions and recorded EkaScribe demonstration sessions with our internal medical professionals. Additional high-quality content was sourced from speakers across four different medical colleges, providing diverse regional accents and speaking styles representative of India's medical education landscape.

Target Applications

This dataset is valuable for developers building and evaluating voice-enabled healthcare applications, and medical documentation systems that rely on speech-to-text functionality. Healthcare institutions implementing AI-powered scribe solutions will find this dataset essential for evaluating system performance across diverse Indian linguistic contexts.

Usage

Load specific subset and split:

from datasets import load_dataset

# Load specific subset and split
dataset = load_dataset('ekacare/eka-medical-asr-evaluation-dataset', 'en', split='test')

# Load all splits from a subset
dataset = load_dataset('ekacare/eka-medical-asr-evaluation-dataset', 'en')

# Load everything
dataset = load_dataset('ekacare/eka-medical-asr-evaluation-dataset')

Parrotlet-a-en-5b is an open-weight model released by EkaCare for english language ASR in medical domain

Evaluation Metrics

  • WER (Word Error Rate): Measures the percentage of words that are incorrectly transcribed
  • CER (Character Error Rate): Measures the percentage of characters that are incorrectly transcribed
  • semWER (Semantic Word Error Rate): Evaluates transcription accuracy considering semantic/phonetic equivalences
  • kwWER (Keyword Word Error Rate): Focuses on the accuracy of medical keywords and terminology
