Abstract
A speech recognition apparatus () includes a first model () and a second model (). The first model () is learned by training data with an audio frame as input data, and with, as correct answer data, compressed character string data acquired by encoding character string data represented by the audio frame. The second model () is a learned decoder () acquired by learning an autoencoder () being constituted of an encoder () converting input character string data into compressed character string data, and the decoder () converting, into character string data, the compressed character string data output from the encoder. The speech recognition apparatus () inputs an audio frame to the first model (), inputs, to the second model (), compressed character string data output from the first model (), and thereby generates character string data corresponding to the audio frame.
