Label soft offset vs hard offset of voicing

[MinhChauNGUYEN]

Peaket only analyzes the EGG signal until the last detected glottis closure instant. It would be useful to have information about what happens after this closure: is it held (=hard offset: adduction continues) or released (=soft offset: vocal fold abduction). Here is an example of soft offset

and an example of hard offset

This is not always trivial. Soft offset usually follows soft phonation (with high Oq) and hard offset follows pressed/glottalized voicing, but there are cases like this, where a hard offset occurs after soft phonation:
