This paper aims to provide a guideline for modelling speaker identification and speaker verification by comparing voice similarities between brothers. Five pairs of brothers who are believed to have similar voices participated in this experiment. Before conducted in the experiment, perceptual tests were measured if the voices were similar between brothers. The words were measured in both isolation and context, and the subjects were asked to read five times with about three seconds of interval between readings. Recordings were made at natural speed in a quiet room. The data were analyzed in pitch and formant frequencies using CSL (Computerized Speech Lab), PCQuirer and MDVP (Multi -dimensional Voice Program). It was found that data of the initial vowels are much more similar and homogeneous than those of vowels in other position. The acoustic data showed that voice similarities are strikingly high in both pitch and formant frequencies. It was also found that the correlation coefficient was not significant between parameters above.

This paper deals with voice similarities between sisters who are supposed to have common physiological characteristics from a single biological mother. Nine pairs of sisters who are believed to have similar voices participated in this experiment. The speech samples obtained from one pair of sisters were eliminated in the analysis because their perceptual score was relatively low. The words were measured in both isolation and context, and the subjects were asked to read the text five times with about three seconds of interval between readings. Recordings were made at natural speed in a quiet room. The data were analyzed in pitch and formant frequencies using CSL (Computerized Speech Lab) and PCQuirer. It was found that data of the initial vowels are much more similar and homogeneous than those of vowels in other positions. The acoustic data showed that voice similarities are strikingly high in both pitch and formant frequencies. It is assumed that statistical data obtained from this experiment can be used as a guideline for modelling speaker identification and speaker verification.

This paper proposes on the Sasang constitution classification method which is the most important things in the Sasang constitution medicine. Pre-existing methods of Sasang constitution classification are a shape of the body and its countenance & morpological aspect and temper. Many diagnostic methods have been developed and used including the questionnaires on personal life style and propensities(QSCC, QSCC II), and the tonal analysis of person's voice. Recently the constitutional acupunture and the herbal medicine response analyses are developed and used additionally. But these methods which is done by the doctor's intuition. In this article, I propose a methodology to classify the Sasang constitution. pitch, intensity and formants are used to classify the Sasang constitution by comparing the similarities and differencies of tonal analysis. Finally, the validity of the method is proven through the experiments.
