PROBLEM TO BE SOLVED: To provide a sound model generation apparatus that generates a sound model capable of generating a spectrum which smoothly varies.;SOLUTION: A learning model generation apparatus 100 is provided with a first calculation unit 120 for calculating, from each frame of a sound signal, a feature parameter indicating the spectral shape of the frame, a splitting unit 130 for splitting the sound signal into language sections, each having multiple frames and based on each language level, a parameterization unit 140 for, on the basis of the feature parameter of each of the multiple frames included in the language section, calculating the spectral parameter of the language section, a clustering unit 150 for clustering multiple spectral parameters calculated for multiple language sections, respectively, into multiple clusters on the basis of language information, and a model learning unit 160 for learning a spectral model indicating the features of the multiple spectral parameters from multiple spectral parameters included in the same cluster.;COPYRIGHT: (C)2011,JPO&INPIT
