The effects of age, sex, and vocal tract configuration on the glottal excitation signal in speech are
only partially understood, yet understanding these effects is important for both recognition and
synthesis of speech as well as for medical purposes. In this paper, three acoustic measures related
to the voice source are analyzed for five vowels from 3145 CVC utterances spoken by 335 talkers
839 years old from the CID database Miller et al., Proceedings of ICASSP, 1996, Vol. 2, pp.
849852 . The measures are: the fundamental frequency F0 , the difference between the
"corrected" denoted by an asterisk first two spectral harmonic magnitudes, H1
*
-H2
*
related to the
open quotient , and the difference between the "corrected" magnitudes of the first spectral harmonic
