Voiced: the vocal folds are in contact, the air coming from the lungs causes them to vibrate.
Velar: the back of the tongue lies against the soft palate.
Non-palatalized: the middle of the tongue is in a neutral position, it does not take part in the articulation.
Plosive: a closure in the oral cavity and of the soft palate obstructs the airflow from the lungs, the air-pressure rises, subsequently, there is a quick release of the closure in the oral cavity, i.e. a plosion.
