Abstract

Accurate estimation of the vocal-tract area function (VTAF) requires the vocal-tract filter (VTF) estimated from a vowel signal should not contain the influence of the glottal wave, and the influence of the non-ideal glottal and lip boundary conditions. The method for eliminating the influence of the glottal wave on the VTF estimation from a vowel sound signal is developed. This paper investigates the effect of non-ideal glottal and lip boundary conditions on the estimation of the VTAF.
