Frogs call by passing air through the larynx in the throat.
If it be from paralysis of the larynx, treat with B D current, rather strong force; placing P. P., long cord , on back of neck or in the mouth, and work with N.P. over the larynx , and somewhat over the air tube of the neck generally.
In tlingit, at least, the articulation of ejective fricatives does include complete closure of the glottis before frication begins, and the larynx is raised in the same manner as with ejective stops.
The difference could lie in the size and shape of the larynx itself.
