In this paper, we propose a language model (LM) adaptation method for transcribing disaster broadcasts. Because the disaster itself is an unprecedented event, there might be not enough quantities of training texts for the LM adaptation in the disaster. Then, our proposed method adapts LM in an unsupervised manner by using speech recognition results in addition to the online manuscripts. The proposed method, furthermore, employs a progressive updating procedure, which adapts in a short period to reflect the latest situation of the disaster to the LM. Experimental results showed that the proposed LM adaptation method reduced relatively a word error rate by 8.2% compared with the conventional LM adaptation method with online manuscripts only. |
