PROBLEM TO BE SOLVED: To provide a language model learning device, which is enhanced in recognition accuracy. SOLUTION: The device is provided with object task language data 101, general task language data 102, a similar word couple extracting means 103, a similar word string synthesizing means 104 and a language model generating means 105 for constructing a task adapted language model by reading text data from the respective language data. Then, the similar word couple extracting means 103 reads the respective text data and extracts a similar couple from the combination of words contained in the object task data and words contained in the general task data, the similar word string synthesizing means 104 reads the respective text data and the similar word couple and synthesizes out a word string containing words in an object task, which is not contained in the language data, and the language generating means 105 finds the statistic quantity of the word string by weighting for every text data. |
