MedAstra framework bypasses ASR for improved medical QA

Researchers have developed MedAstra, a novel framework designed to improve spoken medical question answering by bypassing traditional automatic speech recognition (ASR). This system maps speech representations directly into a text embedding space, allowing for retrieval of relevant medical information from waveforms without needing a transcribed query. MedAstra achieves high recall rates, with its speech-only retriever reaching 87.6% Recall@10 and a hybrid configuration achieving 90.4%, outperforming transcript-first dense retrieval methods. AI

IMPACT This framework could enhance the accuracy and efficiency of accessing medical information through spoken queries, potentially improving clinical workflows.

    MedAstra: ASR-less Speech Retrieval with Diagnostic Grounding for Medical QA

    arXiv:2611.01261v1 Announce Type: new Abstract: Spoken medical question answering can fail when automatic speech recognition (ASR) corrupts a clinically important term before retrieval. We present MedAstra, a framework that maps frozen WavLM speech representations through a light…
