Voiceless bilabial implosive

A voiceless bilabial implosive is a rare consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɓ̥⟩ or ⟨pʼ↓⟩. A dedicated IPA letter, ⟨ƥ⟩, was withdrawn in 1993.


Features of the voiceless bilabial implosive:


A rare and evidently unstable sound, /ɓ̥/ is found in the Serer of Senegal, the Owere dialect of Igbo in Nigeria, and in some dialects of the Poqomchi’ and Quiche languages of Guatemala.
