Abstract
The acoustic feature extraction meansextracts an acoustic feature, using predetermined parameters, from an acoustic pattern obtained as a result of processing on an acoustic signal. The language vector calculation meanscalculates a language vector from a given label that represents an attribute of a source of the acoustic signal and that is associated with the acoustic pattern. The similarity calculation meanscalculates a similarity between the acoustic feature and the language vector. The parameter update meanslearns parameters so that the similarity becomes larger, and updates the predetermined parameters to the parameters obtained by learning.
