To alleviate this issue, we propose an ASR error correction method that improves rare word recognition based on error detection and context-aware error correction.

A rare word list is also used to provide additional contextual information for the model to correct errors related to rare words. Experimental results demonstrate that our proposed method outperforms previous works by a large margin in word error rate (WER) on five public datasets while also maintaining a reasonable inference speed.
