| Abstract: | The effects of age, gender, and vocal tract configurations on the glottal 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 (related to H1*-H2*), and spectral tilt (related to H1*-A3*), are not only affected by age and gender but are also intercorrelated. Recordings of 92 male and female speakers from three age groups (8, 15, 20-39) are analyzed. The main observations are: for low-pitched talkers H1*-H2* (hence, the open quotient) is proportional to F0, while for high-pitched talkers H1*-H2* is proportional to F1 (high to low vowels) for F1<700Hz. The parameter H1*-A3* showed a strong dependence on F2 and F3 for all talkers and age groups: increasing F2 or F3 yielded an increase in H1*-A3*. Spectral tilt was seen to be vowel dependent and for male talkers, spectral tilt changed dramatically with age. | ||
