METHOD FOR PROCESSING LANGUAGE MODEL USING CLASSES CAPABLE OF PROCESSING REGISTRATION OF NEW WORDS IN SPEECH RECOGNITION SYSTEM

摘要

PURPOSE: A method for processing a language model using classes capable of processing registration of new words in a speech recognition system is provided to improve the recognition rate without learning using sentences by generating registration classes according to additional new words. CONSTITUTION: If a new word is inputted through a key board, the new word is applied to a CPU so that the CPU registers the new word(301). The CPU searches whether a first new word is registered(302). The CPU searches whether a new registration class is to be set(303). If not, the CPU inserts the new word into the existing class(304). If so, the new registration class is registered(305). The mutual connection probability of registration classes and the generative probability of words are decided whenever a new registration class is generated(306). The sentence probability that the inserted word is generated in the class is decided(307).
