PROBLEM TO BE SOLVED: To provide a sound source parameter estimation device capable of estimating a sound source model parameter in conjunction with a sound source parameter even when no sound source model parameter is given in advance.;SOLUTION: A sound source model parameter update section updates a sound source model parameter using a sound source power feature amount, a sound source power parameter, a sound source occupancy, a preliminary probability density function of the sound source power parameter stored in a sound source model storage section, and a model of the sound source power feature amount as inputs. A sound source occupancy update section updates a sound source occupancy for each sound source using a sound source position feature amount, the sound source power feature amount, the updated sound source power parameter for each sound source, a sound source position parameter, the sound source model parameter, the preliminary probability density function of the sound source power parameter stored in the sound source model storage section, and a model of the sound source power feature amount as inputs.;COPYRIGHT: (C)2012,JPO&INPIT
