Abstract (in Japanese) (See Japanese page) 
(in English) This paper presents a fully automatic word error correction on a confusion network
by employing out-of-vocabulary word modeling.
In usual speech recognition,
there is a problem that speech recognition systems incorrectly recognize OOV words and their neighboring words.
In this paper, we add hybrid word/syllable recognition to the speech recognizer in order to make it recognize OOV words
and to reduce the recognition error around OOV words.
Then, we propose a CRF-based word-error correction method using acoustic and linguistic features.
The proposed method can not only recognize OOV words but also correct the words neighboring OOV words.
