Speech recognition grammatical creation device, speech recognition grammatical creation manner, program, and storage

摘要

A speech recognition grammar creating apparatus and which is capable of eliminating complex labor associated with preparing all rules by taking into account changes of the order of component elements of a speech-recognizing object and possible combinations of component elements including at least one component element that can be omitted. In the speech recognition grammar creating apparatus, an image edit section groups together at least one component element that cannot be omitted and at least one component element that can be omitted, as the speech-recognizing object and into a component element group as an omission-allowed group. An augmented BNF converting section creates the speech recognition grammar by expanding the component element group obtained by the grouping.
