Abstract
A keyword is extracted robustly despite a voice recognition result including an error. A model storage unitstores a keyword extraction model that accepts word vector representations of a plurality of words as an input and extracts and outputs a word vector representation of a word to be extracted as a keyword. A speech detection unitdetects a speech part from a voice signal. A voice recognition unitexecutes voice recognition on the speech part of the voice signal and outputs a confusion network which is a voice recognition result. A word vector representation generating unitgenerates a word vector representation including reliability of voice recognition with regard to each candidate word for each confusion set. A keyword extraction unitinputs the word vector representation of the candidate word to the keyword extraction model in descending order of the reliability and obtains the word vector representation of the keyword.
