摘要
A speech interaction device includes: an obtainment unit that obtains utterance data indicating an utterance made by a user; a memory that holds a plurality of keywords; a word determination unit that extracts a plurality of words from the utterance data and determines, for each of the plurality of words, whether or not to match any of the plurality of keywords; a response sentence generation unit that, when the plurality of words include a first word that is determined not to match any of the plurality of keywords, generates a response sentence that includes a second word, which is among the plurality of words and determined to match any one of the plurality of keywords, and asks for re-input of a part corresponding to the first word; and a speech generation unit that generates speech data of the response sentence.
