Setting here in Germany. I have noticed that many Germans when they are speaking English while they have very good accents that many of them pronounce their V sound as a W as a ___ for example the word university. I hear it uniwersity(?) which is strange because the German wenuversitate(?) has the ___ sound in it. It's exactly the same in English. University. Off course it's just a matter of changing the habit as the sound does exist in the general language. So one just have to be careful when they're speaking that their mouth doesn't go into the position but rather the other words. Is it very valuable(?)?
