摘要
A device, a method, and a medium for establishing a language model for speech recognition are disclosed. The language-model-establishing device includes: a schema expander for expanding a state schema which is composed of at least one state defined by a finite state grammar using a general grammar database; a grammatical-structure-expander for expanding grammatical structures which can be expressed by each state of the expanded state schema using the general grammar database; and a grammatical-structure-filter for filtering out any incorrect grammatical structure from the expanded grammatical structures using the general grammar database. Since the state schema is expanded using the general grammar database, it is possible to improve recognition of unlearned grammatical structures.
