Abstract

An acoustic model learning apparatus includes a parameter updating part configured to update a parameter of a second acoustic model on the basis of a first loss for a feature amount for training, based on output probability distribution of the second acoustic model which is a neural network acoustic model to be trained, and a second loss for a feature amount for training, based on an intermediate feature amount of a first acoustic model which is a trained neural network acoustic model and an intermediate feature amount of the second acoustic model.
