So about the CH sounds then, in the program we are learning it from (and how my gran taught me to say it as well) is with not quite hard, with the back of the tongue not quite touching the roof of the mouth, so some air gets through. I don't know how you would spell it, there is no equivalent sound in an English word that I can think of. But it's betweena hard K and a soft CH. It kind of sounds like you are going to spit, to me, lol.
Is this the "High German" or northern German accent?
My daughter struggles with this sound, and tends to say it closer to "ish", which sound like it is still acceptable, but is southern, or low German?
The other difficult sound for her is the umlaut U, as in "Büch". She also tends to want to say it as the English "oo", as in Book. Combined with the CH, this is a tricky word to say and not sound American.
Any tips on those tricky vowel sounds?
Wow, I didn't realize what I as getting into! lol. I really appreciate all this help though.
