The fricatives are transcribed ⟨ʃ⟩ (voiceless) and ⟨ʒ⟩ (voiced) in the International Phonetic Alphabet, while the corresponding affricates are ⟨tʃ⟩ (voiceless) and ⟨dʒ⟩ (voiced). (For the affricates, tied symbols ⟨t͡ʃ⟩ ⟨d͡ʒ⟩ or unitary Unicode symbols ⟨ʧ⟩ ⟨ʤ⟩ are sometimes used instead, especially in languages that make a distinction between an affricate and a sequence of stop + fricative.) Examples of words with these sounds in English are shin [ʃ], chin [tʃ], gin [dʒ] and vision [ʒ] (in the middle of the word).
