A labio-palatalized sound is one that is simultaneously labialized and palatalized. Typically the roundedness is compressed, like {{IPA|[y]}}, rather than protruded like {{IPA|[u]}}. The symbol in the International Phonetic Alphabet for this secondary articulation is {{angbr IPA|ᶣ}}, a superscript {{angbr IPA|ɥ}}, the symbol for the labialized palatal approximant. If such sounds pattern with other, labialized, consonants, they may instead be transcribed as palatalized consonants plus labialization, {{angbr IPA|ʷ}}, as with the {{IPA|[sʲʷ]}} = {{IPA|[sᶣ]}} of Abkhaz or the {{IPA|[nʲʷ]}} = {{IPA|[nᶣ]}} of Akan.

A voiced labialized palatal approximant {{IPA|[ɥ]}} occurs in Mandarin Chinese and French, but elsewhere is uncommon, as it is generally dependent upon the presence of front rounded vowels such as {{IPAblink|ø}} and {{IPAblink|y}}, which are themselves not common.{{cite book |last=Maddieson |first=Ian |title=Patterns of Sounds |series=Cambridge Studies in Speech Science and Communication |page=95 |isbn=0-521-26536-3 |publisher=Cambridge University Press |year=1984}} However, a labialized palatal approximant and labio-palatalized consonants appear in some languages without front rounded vowels in the Caucasus and in West Africa,{{cite book |last=Maddieson |first=Ian |title=Patterns of Sounds |pages=92, 292 |year=1984}} such as Abkhaz, and as allophones of labialized consonants before {{IPA|/i/}}, including the {{IPA|[tsᶣ]}} at the beginning of the language name Twi. In Russian, {{IPA|/o/}} and {{IPA|/u/}} trigger labialization of any preceding consonant, including palatalized consonants, so that нёс 'he carried' is phonetically {{IPA|[nᶣɵs]}}.

Iaai has a voiceless labialized palatal approximant {{IPA|/ɥ̊/}}.
