    <Paragraph position="0"> To facilitate retrieving information by spoken queries, the out-of-vocabulary problem in speech recognition needs to be resolved. In our proposed method, out-of-vocabulary words in a query are detected by speech recognition, and completed with terms indexed for text retrieval, so as to improve the recognition accuracy. In addition, the completed query is used to improve the retrieval accuracy. We showed the effectiveness of our method by using dictated queries in the IREX collection. Future work would include experiments using larger-scale test collections in various domains.</Paragraph>
