Labialized palatal approximant

Extracted from the Wikipedia article Voiced labial–palatal approximant.
Some languages, though, have a palatal approximant that is unspecified for rounding, and therefore cannot be considered the semivocalic equivalent of either [y] or its unrounded counterpart [i]. An example of such a language is Spanish, in which a labialized palatal approximant (non-semivowel) appears allophonically with back vowels in words such as ayuda[aˈʝ̞ʷuð̞a] ('help'), while unrounded elsewhere, such as ayer[aˈʝ̞eɾ] ('yesterday'). Therefore, according to some sources, it is not correct to transcribe this sound with the symbol ⟨ɥ⟩, which has a different kind of rounding, or with a modified ⟨j⟩, which according to the same sources cannot be rounded at all; the only suitable transcription is ⟨ʝ̞ʷ⟩. See palatal approximant § Phonetic ambiguity and transcription usage for more information.
