자매 발화의 분석과 인식에 관한 연구

As a pan of voice identification, this study is on the voices from four different groups of sisters. The purpose of this study is to observe and analyze if sister's voices are actually so similar, as many people believe, that it is more difficult to distinguish one from the other than those of unrelated speakers. And it is also aimed to find out what the clues are to decide whether or not the voices are those of the same speaker or of different ones. The result shows that the mean frequencies of $F_3$ and $F_4$ of examined vowels and F0, in some group of sisters, are analyzed similar, In aural test, many listeners took their voices for those of the same speaker.
