ABSTRACT
The effects of age, gender, and vocal tract configurations on the glot-
tal excitation signal are still only partially understood. In this paper
we examine some of these effects, and show that the voice source
parameters, such as fundamental frequency (F0), open quotient (re-
lated to H
1 -H
2 ), and spectral tilt (related to H
1 -A
3), are not only
affected by age and gender but are also intercorrelated (the asterisk
superscript denotes correction for the influence of various formants).
Recordings of 92 male and female speakers from three age groups
(8, 15, 20-39) are analyzed. The main observations are: for low-
