LLMs Compared for ASR Evaluation: Encoder vs. Generative Models

A new study published on arXiv explores the effectiveness of encoder and decoder-based Large Language Models (LLMs) for evaluating Automatic Speech Recognition (ASR) systems. The research compares metrics like BERTScore and SemDist across various LLMs and configurations, finding that both can achieve strong correlations with human judgments when properly set up. The study also highlights that generative LLMs show promise in hypothesis comparison and error classification for ASR evaluation, offering improved interpretability. AI

IMPACT This research could lead to more accurate and interpretable evaluation methods for speech recognition systems.

    Generative vs. Encoder Large Language Models for ASR Evaluation: A Comparative Study

    arXiv:2608.25574v1 Announce Type: new Abstract: Automatic Speech Recognition (ASR) is typically evaluated using Word Error Rate (WER), which poorly reflects semantic similarity. While embedding-based metrics correlate better with human judgments, the respective roles of encoder a…
