| Abstract(in English) | Analysis-synthesis coding method of speech called CELP in VoIP and cellular phones are used. It is believed to be able to extract the individuality from the parameters obtained from the encoder of the CELP, it is possible to prevent a crime that masquerade as another person by using the terminal of the mobile, and help to speaker verification. However, there is a problem that undesirably lacks in practicality, since the authentication rate is lowered in a short speech time. In this study, by using the registered voice of a total of 2 seconds of 5 vowel (/a/～/o/), practical application for registration purpose is improved. Moreover, the comparison was made by using a conversational speech 2 seconds and 20 seconds for evaluation voice. Result of speaker authentication experiments 10 people, one of the conversational speech of 20 seconds or 2 seconds, even to obtain a certification rate of 92%. |
