PROBLEM TO BE SOLVED: To provide the voice recognition device in which an efficient voice recognition is conducted by appropriately classifying the contents of a voice dictionary. SOLUTION: When the device conducts a voice recognition, a beginning word vowel and an ending word vowel are comparatively less affected by other sounds and are easily recognized. Using this theory, a word dictionary is classified into plural individual dictionaries for each word, which are the objects of voice recognition, based on the combination of the beginning word vowel and the ending word vowel of the word. Then, a pattern matching section 165 and a discriminating section 166 conduct the prerecognition of the beginning word vowel and the ending word vowel from the similarity between the beginning and ending word portions of the features extracted by a feature extracting section 162 and the standard patterns of a vowel dictionary 163a. Then, the pattern matching of the inputted voice recognition is conducted with the priority to the individual dictionary of the combination of the both vowels. |
