Abstract: A speech data retrieving Web site system is provided which may improve erroneous indexing with participation of a user by allowing the user to correct text data obtained by conversion using a speech recognition technique. Speech data published on a Web is converted into text data by a speech recognition section 5. A text data publishing section 11 publishes the text data obtained by conversion of the speech data in a state searchable by a search engine, downloadable together with related information corresponding to the text data, and correctable. A text data correcting section 9 corrects the text data stored in a text data storage section 7, according to a correction result registration request supplied from a user terminal device 15 through the Internet.
