Abstract
Provided is a word vectorization device that converts a word to a word vector considering the acoustic feature of the word. A word vectorization model learning device comprises a learning part for learning a word vectorization model by using a vector wL,s(t) indicating a word yL,s(t) included in learning text data, and an acoustic feature amount afL,s(t) that is an acoustic feature amount of speech data corresponding to the learning text data and that corresponds to the word yL,s(t). The word vectorization model includes a neural network that receives a vector indicating a word as an input and outputs the acoustic feature amount of speech data corresponding to the word, and the word vectorization model is a model that uses an output value from any intermediate layer as a word vector.
