positional variant (does not occur in isolation)
Based on Maciołek & Tambor (2012)
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.
Palatalized: the middle of the tongue gets closer to the hard palate as a secondary articulation.
Nasal: there is a closure in the oral cavity, the soft palate moves away from the back of the pharyngeal cavity and enables the free flow of air through the nasal cavity and out. After that, the closure in the oral cavity is released.
