Speaker individualities in F0 contours are investigated through analyses of several speakers uttered speech and psychoacoustic experiments. The stimuli for the experiments are re-synthesized with manipulated F0 contours and spectral envelopes averaged overall speakers by using the Log Magnitude Approximation analysis-synthesis system. The analysis and experimental results indicate that (1) there are speaker individualities in the F0 contours, (2) some specific parameters related to the dynamics of F0 contours have many speaker individuality features and the speaker individualities can be controlled by manipulating these parameters, and (3) although there are speaker individuality features in the time-averaged F0 contours, they help improve speaker identification less than the dynamics of the F0 contours.
