概要	The voices of 5 subjects were recorded with and without experimental bite plates.The voice samples were analyzed with “VOICE PASSPORT EMBEDDED”，which is software for judging individual sound recognition(Animo Limited).Rates of individual recognition were observed. There were significant changes in the rates of indivisual recognition achieved by bite-raising.So it is necessary to use the biometric security system with sound recognition for patients who have dentures with different vertical dimensions.
