PPROBLEM TO BE SOLVED: To provide a clustering system capable of clustering a language model in which vocabularies appeared in voices of a plurality of speakers or written characters thereof are collected. PSOLUTION: The clustering system 1 for clustering a language model group comprises: a sum of sets language model creating section 15 for creating a sum of sets language model for each language model, which includes sum of sets of the vocabularies included in a language model group, as an entry; and a clustering section 14 for classifying a sum of sets language model group into a plurality of clusters by clustering the sum of sets language model group. When the sum of sets language model creating section 15 creates the sum of sets language model about a certain language model, appearance frequency of the entry corresponding to the language model is recorded, regarding the vocabularies which is included in the basic language model, and data indicating the appearance frequency is zero is recorded, regarding the vocabularies which is not included in the language model.
