Sj-sound


The sj-sound is a voiceless fricative phoneme found in most dialects of the sound system of Swedish. It has a variety of realisations, whose precise phonetic characterisation is a matter of debate, but which usually feature distinct labialization. The sound is represented in Swedish orthography by a number of spellings, including the digraph from which the common Swedish name for the sound is derived, as well as,, and . The sound should not be confused with the Swedish tj-sound, often spelled,, or .
The sound is transcribed in the International Phonetic Alphabet. The International Phonetic Association describes it as a "simultaneous and ", but this realization is not attested from any language, and phoneticians doubt that it exists.

Kölsch

A sound transcribed as is also reported to occur in the Kölsch variety of Ripuarian in Germany, being articulated in positions in words that enveloping Standard German has.
The acoustic difference between and the Kölsch is difficult to perceive but the articulation is clearly distinct. Whether or not there is a relation between Swedish and the Kölsch is not known. While none seems to have been established, comments suggest that the choice of might well have been based upon a misunderstanding. Certainly, the Kölsch is not doubly articulated and even contrasts with a slightly velarized.
Some phoneticians suggest contrasting with, as is done in Polish, but this is not established practice, and may need further research.
