| Research Abstract |
This research attempted to achieve the high accuracy speech recognition for news speech using a language model constructed from Web documents collected with keywords in speech recognition results. In addition, the method estimating confidence of speech recognition results from clustering results of collected Web documents was proposed. Moreover, the method constructing network grammar automatically was investigated for multi-word expression in oral sentences.
