Error-Aware TF-IDF Retrieval-Augmented Generation for ASR Error Correction
Researchers propose an error-aware TF-IDF retrieval-augmented generation framework that corrects automatic speech recognition (ASR) errors by using phonetically-aware lexical matching rather than heavy cross-modal embeddings. The method achieved a 37.2 percentage-point improvement in error-aware hit rate and reduced word error rate by 4.23 points on Persian speech data with minimal computational overhead.
