Phonetic changes
Fragment of a discussion from User talk:Rua
@UtherPendrogn I would base the future French conlang on nowadays youth talk. You can listen to the basic explanation (examples from American US) in this audio (and read it here, but notice that they do not say exactly the same, and it's not only the order what changes), by James Harbeck. I hope you not to be dismayed when knowing that the future, like the past, can't be predicted (audio or text). Other source could be even modern dialects.
