PROBLEM TO BE SOLVED: To obtain a speech retrieval device with which speech itself is used for a retrieval condition, and the speech in which a number of accent kernels are contained in one accent phrase or one clause, is made as a retrieval unit. SOLUTION: The device for retrieving the speech which meets the retrieval condition by making the input speech as the retrieval condition, from a speech data base 150, includes: a speech input section 110 for inputting the speech; a speech analysis section 120 for calculating a feature amount of the speech which is input to the speech input section 110; and a form extraction section 130 for calculating a time series form of the feature amount calculated by the speech analysis section 120. The form extraction section 130 calculates difference between the time series form of the feature amount calculated by the speech analysis section 120, and the time series form of the feature amount of the speech stored in the speech data base 150, and outputs the speech in which the difference is a prescribed threshold or less, as a retrieval result.
