PROBLEM TO BE SOLVED: To provide an indexing device which can conduct accurate indexing. SOLUTION: The indexing device provides an index to an acoustic signal and is provided with an obtaining means 102 which obtains the acoustic signal; a dividing means 104 which divides the acoustic signal into a plurality of segments; an acoustic model generating means 106 which generates an acoustic model for each of the segments; a degree of reliability determining means 108 which determines the degree of reliability of the acoustic models; a degree of similarity vector generating means 110 that generates a degree of similarity vector, in which the degree of similarity between the acoustic model generated for a prescribed segment and the acoustic signal for an other segment is used as an element, based on the degree of similarity of the acoustic model; a clustering means 112 which conducts clustering of a plurality of the degree of similarity vectors; and an index adding means 114, which imparts an index to the acoustic signal based on the clustered degree of similarity vector.
