By the way, there is not a single “Chassidishe” Yiddish either. The “Ingarisch” (Lipanese) dialect spoken in Skvere, Satmar, Vizhnitz etc is different from Galitzianer or “Poylishe” Yiddish of Ger, Belz, Bobov etc. I hear the difference more in loshon hakoidesh: Hashem (Ingarisch) vs Hashyme (Poylish) is the most pronounced difference. Probably, the difference in Yiddish is really heard more in words that come from loshon hakoidesh.
And then there is the regional Litvish difference between “oy” and “ay”.
