The bilabial consonants identified by the International Phonetic Alphabet (IPA) are:
|voiceless bilabial stop||English||spin||[spɪn]|
|voiced bilabial stop||English||bed||[bɛd]|
|voiceless bilabial fricative||Japanese||富士山 (fujisan)||[ɸuʑisaɴ]||Mount Fuji|
|voiced bilabial fricative||Ewe||ɛʋɛ||[ɛ̀βɛ̀]||Ewe|
|bilabial trill||Nias||simbi||[siʙi]||lower jaw|
|bilabial click release (many distinct consonants)||Nǁng||ʘoe||[ʘoe]||meat|
Owere Igbo has a six-way contrast among bilabial stops: [p pʰ ɓ̥ b b̤ ɓ]. Approximately 0.7% of the world's languages lack bilabial consonants altogether, including Tlingit, Chipewyan, Oneida, and Wichita.
The extensions to the IPA also define a bilabial percussive ([ʬ]) for striking the lips together (smacking the lips – see percussive consonant). A lip-smack in the non-percussive sense of the lips noisily parting would be [ʬ↓].
The IPA chart shades out bilabial lateral consonants, which is sometimes read as indicating that such sounds are not possible. The fricatives [ɸ] and [β] are often lateral, but no language makes a distinction for centrality so the allophony is not noticeable.
