PROBLEM TO BE SOLVED: To provide a document retrieving device capable of highly accurately retrieving an electronic document suited to a retrieving purpose by a voice input. SOLUTION: Recognition tolerance and recognition time are applied to one or plural keyword candidates recognized from an input voice. An weighting information applying part 22 calculates retrieving weight in each keyword candidate from the recongition tolerance and time elapsed from the recognition time. A word merging part 24 merges retrieving weight values as to identical keyword candidates. A word determination part 25 specifies a keyword candidate having the highest retrieving weight as a retrieving keyword and outputs the specified candidate to a document management part 30. The management part 30 calculates retrieving weighted word importance in each electronic document based on the retrieving keyword and retrieves an electronic document having the highest retrieving weighted word importance from an electronic document DB 40.
