This study aims to investigate the extent to which listeners can judge some unknown speakers' acoustic characteristics. Moreover, we tried to evaluate correlation of the chronological ages with various acoustic characteristics: pitch, open quotient, spectral tilt, harmonics-to-noise ratio, shimmer, jitter and MFCC. In this paper, we propose a relative estimation method for subjective age by using speaker's acoustical characteristics and their chronological age. A relative estimation task is performed, wherein an estimator gives rating values to other people about whether they are older or younger than the estimator. In this task, we measured the difference in the actual age between the estimator and the subjective age.
