Abstract

|
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 reading. 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 sililar and homogeneous than those of vowels in other positions. The acoustic data showed that voice similarities are strikingly high in both pitch and format frequencies. It is assumed that statistical data obtained from this experiment cas be used as a guideline for modelling speaker identification and speaker verification.
