The 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, and the equivalent X-SAMPA symbol is C. The symbol ç is the letter c with a cedilla, as used to spell French words like façade, although the sound represented by the letter ç in either French or English orthography is not a voiceless palatal fricative, but simply [s], the voiceless alveolar fricative.
Features
Features of the voiceless palatal fricative:
In some dialects of English, the sequence /hj/ is sometimes realized as the voiceless palatal fricative, via coalescence, a type of assimilation. For example, human (/ˈhjumən/ might be realized as [ˈçumən]). However, there are no minimal pairs for /hj/ and /ç/, so the voiceless palatal fricative is not a separate phoneme in English.
In other languages
German has the voiceless palatal fricative as a phoneme, and it is denoted by "ch", as in ich /ɪç/ (the pronoun I). The Germans call this sound ich-Laut. This is the sound represented by "ch" when it follows "e", "i", "ä", "ö", "ü", the diphthongs "eu" or "äu", or the consonants "l", "n" or "r". The sound represented by "ch" following "a", "o", "u", or the diphthong "au" is a different consonant, the voiceless uvular fricative.
