Abstract (in Japanese) (See Japanese page) 
(in English) According to the increase of multimedia contents, many users want a new function to watch the video section of their interest easily. For this purpose, many Spoken Term Detection (STD) researches have been conducted using results of a speech recognizer. Such methods have a difficulty in dealing with out-of-vocabulary (OOV) words for a speech recognizer. The STD task becomes more difficult for the speech in video data when an OOV query is given by speech because the speech cannot be recognized into the correct word by a speech recognizer. Therefore, we have proposed a method to enable to retrieve an OOV word section by using phone sequences obtained form the result of a speech recognizer. The paper proposes a method to deal with an OOV speech query by extending the vocabulary that is extracted from Web assuming the correct words of an OOV speech query exist on Web, and the vocabulary can cover OOV speech query. The method enabled to detect an OOV speech query and improved the retrieval performance for an in-vocabulary speech query.
