PURPOSE:To improve the recognition rate of nonstandard words by composing recognition and decision parts of standard patterns of standard words and special patterns by voicing methods characteristic to regions and deciding the similarity of each pattern simultaneously. CONSTITUTION:A standard memory part 27 is stored with an average weighted pattern group of many data gathered as to the standard words. A special memory part 28, on the other hand, is stored with an average weighted pattern group of many data gathered as to accents, etc., characteristic to the regions. Normalized input voice data are inputted to a standard recognition and decision part 24 and a special recognition and decision part 25 at the same time and processed by a standard decision part 29 and a special decision part 30 in parallel and a final decision part 26 outputs a category name added to a pattern which is smaller in minimum sum value as a recognition result. Consequently, the recognition rate regarding nonstandard words can be improved. |
