A voiceless postalveolar fricative is a type of consonantal sound used in some spoken languages.The International Phonetic Association uses the term voiceless postalveolar fricative only for the sound [ ʃ ], [1] but it also describes the voiceless postalveolar non-sibilant fricative [ɹ̠̊˔], for which there are significant perceptual differences.
The voiceless palato-alveolar sibilant affricate or voiceless domed postalveolar sibilant affricate is a type of consonantal sound used in some spoken languages. The sound is transcribed in the International Phonetic Alphabet with t͡ʃ , t͜ʃ tʃ (formerly the ligature ʧ ), or, in broad transcription, c .
The voiceless palato-alveolar affricate /t͡ʃ/ may be pronounced as its closest Russian equivalent, /t͡ɕ/. The postalveolar fricatives /ʃ/ and /ʒ/ may be realised as their closest Russian equivalents, /ʂ/ and /ʐ/. The consonant cluster /t/ /s/ may be realised as an affricate, /t͡s/.
In /tr/, as in tree, it is a voiceless postalveolar fricative [ɹ̠̊˔] or less commonly alveolar [ɹ̝̊]. [6] In England, while the approximant has become the most common realization, /r/ may still be pronounced as a voiceless tap [ɾ̥] after /θ/ (as in thread). [7]
pharyngealized voiced postalveolar fricative [ʒˤ] (in Kabyle and Chechen) pharyngealized voiceless dental fricative [θˤ] (in Zenaga, Shawiya and Shehri) pharyngealized voiced dental fricative [ðˤ] ⓘ (in Arabic ظ, and as [θ̬ˤ], a variant pronunciation in Mehri) pharyngealized voiceless alveolar lateral fricative [ɬˤ]
Postalveolar, which means it is articulated with either the tip or the blade of the tongue behind the alveolar ridge, termed respectively apical and laminal. Its phonation is voiceless, which means it is produced without vibrations of the vocal cords. It is an oral consonant, which means air is allowed to escape through the mouth only.
The closest sound found in English, as well as many other languages, is the voiceless postalveolar fricative [ʃ] (Swedish words with the sound often correspond to English words with "sh", such as "shield", "shoot"), although usually the closest audible approximation is the voiceless labialized velar approximant [ʍ] found in some English dialects.
