PROBLEM TO BE SOLVED: To improve speech recognition rate. SOLUTION: A word preliminary selection section 13 selects a word string, that is connected to the words for which scores are already computed and are made up with several words, from a dictionary database 18A. A matching section 14 computes a score for the leading word, that is the leading word of the word string, based on more than one word following the leading word of the word string. Then, a word connection information storage section 16 stores the connecting relationship between the leading word whose score is computed and the word that is connected with the leading word and the score is already computed. A control section 11 decides a speech recognition result, based on the connecting relationship and the score. |
