Overall, these findings are consistent with previous literature showing acoustic differences between voiced and whispered speech beyond the articulatory change of eliminating fundamental frequency.This study considers the propagation of surface waves along all directions on the plane boundary of piezo-poroelastic half-space with arbitrary anisotropy. This generalised propagation is characterized through an anisotropic phase velocity, which should ensure the decay of wave-field with depth into the medium. A linear homogeneou
