摘要： An information retrieval system including: a calculating unit which calculates a query language model that is a language model of an input word or of a set of input words; an extracting unit which refers to a storage means storing a result of speech recognition on speech data which is speech-recognized with use of a speech recognition language model, and extracting a result indicating a high degree of similarity to the query language model from the result, as matching data; a first updating unit which updates the speech recognition language model with use of the matching data; and a second updating unit which updates the result stored in the storage means, with use of the updated speech recognition language model, wherein the extracting means extracts a result indicating a high degree of similarity to the query language model from the updated result, and outputs a retrieval result indicating data associated with the extracted result.
