Method of adding vocabulary to a speech recognition system

摘要

A method and a system for use in a computer speech recognition system for adding new vocabulary by using language model statistics corresponding to an existing vocabulary word. The method involves a series of steps including receiving a user input identifying a first word for which no language model statistics exist in the speech recognition system. The first word is for inclusion within the existing vocabulary of the speech recognition system. In response to a second user input identifying a second word for which language model statistics exist in the speech recognition system, recalling from a computer memory the language model statistics for the second word. The speech recognition system then automatically creates language model statistics for the first word by duplicating the language model statistics of the second word and replacing each occurrence of the second word in the duplicated language model statistics with the first word.
