Franco-Provençal

j'

j’ m or f

Je in formal French only becomes j’ before a vowel or an unaspirated h, where this is mandatory in spelling.
In informal French, j’ may optionally be used before consonants, and devoices before unvoiced consonants, thus producing a ʃ sound, as in sheep.
- Before voiced consonants:
  J’vais bien. ― Doing fine.
  
  J’descend tout de suite! ― Coming down!
- whereas before unvoiced consonants:
  Chais pas. (j’sais pas) ― Dunno.
  
  Ch’peux pas. (j’peux pas) ― I can't.
Note that the ch’ spelling (and the j’ spelling before a vowel) is purely oral, it is not used in any type of written content except if one wishes to emphasize the language register spoken or the form is in itself a fixed expression.
