LANGUAGE MODEL CREATION DEVICE, LANGUAGE MODEL CREATION METHOD, AND COMPUTER-READABLE RECORDING MEDIUM

摘要

A language model creation device (200) for creating a new language model using a standard language model created from standard language text is used. The language model creation device (200) is provided with a transformation rule storage section (201) for storing a transformation rule for transforming a word string including a dialect into a standard language word string, and a dialect language model creation section (203) for applying the transformation rule to word n-grams in the standard language model, creating n-grams including the dialect, and adding the created n-grams including the dialect to the word n-grams to create the new language model (dialect language model).
