THE METHOD AND APPARATUS FOR GENERATING EXTENDABLE CFG TYPE VOICE RECOGNITION GRAMMAR BASED ON CORPUS

摘要

A method and an apparatus for generating an extendable CFG-type voice recognition grammar based on a corpus are provided to describe and extend a CFG-type voice recognition grammar even when the corpus is small to perform continuous voice recognition in a specific area, thereby improving the accuracy and efficiency of the voice recognition. A method for generating an extendable CFG(Context-Free Grammar)-type voice recognition grammar based on a corpus comprises the following steps of: converting the corpus into a CFG-type voice recognition grammar pattern by using thesaurus or converting rules(S200); adding at least one of language used in a conversational style, low-ranking words included in a thesaurus, words used in a corresponding voice recognition area, and synonyms of declinable words to the CFG-type voice recognition grammar pattern to extend the CFG-type voice recognition grammar pattern(S300); and removing impossible to express in meaning in the extended CFG-type voice recognition grammar pattern(S400).
