Frequency
Bilabial consonants are very common across languages. Only around 0.7% of the world's languages lack bilabial consonants altogether, including Tlingit, Chipewyan, Oneida, and Wichita,[1] though all of these have a labial–velar approximant /w/.
Varieties
The bilabial consonants identified by the International Phonetic Alphabet (IPA) are:
Owere Igbo has a six-way contrast among bilabial stops: [p pʰ ɓ̥ b b̤ ɓ].[citation needed]
Other varieties
The extensions to the IPA also define a bilabial percussive ([ʬ] ⓘ) for smacking the lips together. A lip-smack in the non-percussive sense of the lips noisily parting would be [ʬ↓].[7]
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 since no language makes a distinction for centrality, the allophony is not noticeable.
