Abstract
Learning meansgenerates a speaker embedding extracting neural network by learning a weighting factor so as to minimize a loss function indicating an error between a speaker label indicating a speaker of a voice signal and an output value output from an output layer, with respect to a neural network including an input layer that receives an input of the voice signal and the output layer that outputs the output value indicating a speaker of the voice signal. The speaker embedding extracting neural network includes a network that calculates a first accuracy from a feature in units of frames and calculates an average and a second accuracy of a posterior distribution from an average and an accuracy of a prior distribution and the feature and the first accuracy.
