Labialized palatal approximant
The labialized palatal approximant, also called the labial–palatal or labio-palatal approximant, is a type of consonantal sound, used in some spoken languages. It has two constrictions in the vocal tract: with the tongue on the palate, and rounded at the lips. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɥ⟩, a rotated lowercase letter ⟨h⟩, or occasionally ⟨jʷ⟩, since it is a labialized [j].
The labialized palatal approximant is the semivocalic equivalent of the close front rounded vowel [y]. The two are almost identical featurally. They alternate with each other in certain languages, such as French, and in the diphthongs of some languages, ⟨ɥ⟩ and ⟨y̯⟩ with the non-syllabic diacritic are used in different transcription systems to represent the same sound.

Features of the labial-palatal approximant:

• Its manner of articulation is approximant, which means it is produced by narrowing the vocal tract at the place of articulation, but not enough to produce a turbulent airstream.
• Its place of articulation is called labio-palatal, which means it is labialized palatal, accomplished by raising the body of the tongue toward the palate while rounding the lips.
• Its phonation is voiced, which means the vocal cords vibrate during the articulation.
• It is an oral consonant, which means air is allowed to escape through the mouth only.
• It is a central consonant, which means it is produced by directing the airstream along the center of the tongue, rather than to the sides.
• The airstream mechanism is pulmonic, which means it is articulated by pushing air solely with the lungs and diaphragm, as in most sounds.
