Abstract(in English) | Recently, in word speech recognition, cepstram is normally used as parameters. And, pitch information is not normally used because it is difficult to extract pitch frequency steady. However, in recent reserches, it is known that there is a relation between pitch frequency and mora information. Then in this paper, we performed word speech recognition using mora information in stead of pitch and examined its validity. In the results, by using mora information, error rate of word speech recognition could decrease for many speeker. And comparing the results of word speech recognition using mora information with using begining and ending of a word or using triphone, the recognition rate using mora information was higher. And the efficiency of this way was confirmed. |
