IPA [j̃]
AS [ĩ̯]
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.
Palatal: the middle of the tongue gets close to the hard palate in the highest part of its vault.
Nasal approximant: the articulators get closer than with vowels but less than with fricatives. 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.
