ⓘ Voiceless bilabial trill

The voiceless bilabial trill is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ ʙ̥ ⟩.

This sound is typologically extremely rare. This occurs in languages such as para Arar and Sercquiais.

Only a few languages contrast voiced and voiceless trills bilabial phonemically, for example, Mangbetu of Congo and Ninde of Vanuatu.

There is also a very rare deaf alveolar affricates bilabially sang.
