PROBLEM TO BE SOLVED: To provide a system and a method to improve speech recognition. SOLUTION: A user of the system can directly talk to the system and the system responds with the language being uttered by an appropriate answer. When the system for a specific application is to be mounted, a grammar rule can automatically be generated from a sample uttering. A dynamic grammar rule can also be generated while mutual operations are conducted between the user and the system. In order to further improve the speech recognition in addition to arrange the retrieval order of the grammar rule based on a beforehand set hierarchy, the retrieval order, which is dynamically generated based on the history of the context of single conversation, can be provided. By recording and extracting the dialogue between the system and the user, a language model can be refined or created using a speech recognition engine and accuracy in speech recognition related to a specific knowledge region may be improved.
