A device comprises a speaker model derivation means for deriving a speaker model for defining a voice property per speaker from speech data made of multiple utterances to which speaker labels as information for identifying a speaker are given, a speaker co-occurrence model derivation means for, by use of the speaker model derived by the speaker model derivation means, deriving a speaker co-occurrence model indicating a strength of a co-occurrence relationship between the speakers from session data which is divided speech data in units of a series of conversation, and a model structure update means for, with reference to a session of newly-added speech data, detecting predefined events, and when the predefined event is detected, updating a structure of at least one of the speaker model and the speaker co-occurrence model.
