Most previous language models had difficulties in transcribing podcasts because podcasts because podcasts include various kinds of tasks and cover recent topics that tend to have many out-of-vocabulary words. To overcome such difficulties, we improve our speech recognizer by using language modeling that utilizes \"Web keywords\" updated on a daily baais through wisdom of crowds. From our experimental results for actual podcast speech data, the effectiveness of the proposed language modeling was confirmed.
