摘要

The purpose of the present invention is to promptly determine a response according to the intention of a speaker who speaks using various expressions. A speech interaction device (1) is provided with an intention index generation unit (25) for generating an intention index representing the intention of a user generated by analyzing the speech of the user, and a response descriptor retrieving unit (29) for identifying a response descriptor corresponding to the intention index generated by the intention index generation unit (25) with reference to a response descriptor retrieval table (42) that maps intention index to response descriptors.
