抄録

The purpose of this experiment was to correspond for the voice security system when the patients wore the dentures. Because the phonetic disorder by the dentures some troubles in the biometric security system with sound recognition, for example, the cash cards, the credit cards and the lock of the doors. But there was few report about the individual recognition by the palatal plates. So we observed the changes of the rates of individual recognition by the palatal plates. The voices of 5 subjects were recorded without the experimental palatal plates and with them. The voice samples were analyzed with the soft for judging the individual recognition rates by the voices. And the rates of individual recognition, the time durations and the pitch curves for every word were observed. By the palatal plates, the rates of individual recognition decreased, the time durations increased, the pitch curves changed little. And by the palatal plates, there were significance (p<0.05) about the rates of individual recognition and the time durations, but there were not significance (p<0.05) about the pitch curves by the two-way layout ANOVA. The frequencies of the pitch curve changed by the vocal chords vibration and affected to the height of the voice. So they did not change by the labial and buccal plates. Therefore they will be able to use for the individual recognition system.
