This paper aims to provide a guideline for modelling speaker indentification and speaker verification by comparing voice similarities between brothers. Five pairs ofbrothers 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. Tfhe 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 inital vowels are much more similar and homogeneous than those of vowels in other position. Tfhe 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 betgween parameters above.
