A voiceless palatal fricative is a type of consonantal sound used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ç⟩. It is the non-sibilant equivalent of the voiceless alveolo-palatal fricative. Palatal fricatives are relatively rare phonemes, and only 5% of the world's languages have as a phoneme. The sound further occurs as an allophone of, or, in other languages, of in the vicinity of front vowels.
