Editing Bilabial consonant (section)

== Other varieties ==
The [[extensions to the IPA]] also define a '''{{vanchor|bilabial percussive}}''' ({{IPAblink|ʬ|audio=y}}) for [[percussive consonant|smacking the lips together]]. A lip-smack in the non-percussive sense of the lips audibly parting would be {{IPA|[ʬ↓]}}.<ref>{{cite book |last=Heselwood |first=Barry |title= Phonetic Transcription in Theory and Practice |year=2013 |page=121 |doi=10.3366/edinburgh/9780748640737.001.0001 |publisher=Edinburgh University Press |jstor=10.3366/j.ctt9qdrqz|isbn=978-0-7486-4073-7 |s2cid=60269763 }}</ref>

The [[IPA chart]] shades out ''bilabial lateral consonants'', which is sometimes read as indicating that such sounds are not possible. The fricatives {{IPA|[ɸ]}} and {{IPA|[β]}} are often lateral, but since no language makes a distinction for centrality, the allophony is not noticeable.
