SPEECH RECOGNITION WORD DICTIONARY/LANGUAGE MODEL MAKING SYSTEM, METHOD, AND PROGRAM, AND SPEECH RECOGNITION SYSTEM

摘要

A speech recognition word dictionary/language model making system for creating word dictionary for recognizing a word not appearing in a learning text by selecting a word-generation-model-learning-method-by-word-class according to the word to be added which does not appear in the learning text and for making a language model. The speech recognition word dictionary/language model making system (100) comprises language model estimating means (111) for selecting estimating method information from a learning-method-by-word-class knowledge storage section (109) for each word class of an addition word which does not appear in a learning text (101) and making, for each class, an addition word generating model which is a word generating model of the addition word according to the selected estimating method information and database combining means (112) for adding an addition word to a word dictionary (105) and adding an addition word generating model to a word-generating-model-by-word-class database (107).
