I made this video while living in Germany specifically with Germans in mind. I have noted, however, that others, for example some of my Indian friends, make the same pronunciation mistake.

Video Text:

As I am studying here in Germany, I have noticed, many Germans, when they are speaking English, while they have very good accents, that many of them pronounce the V sound as a W. Vv as a ww, ww. For example, the word university. Vv. I hear it: uni-wer-sity. Which is stange, because the German word, Universität, has the vv sound in it. It's exactly the same in English: vv, university. Of course, it's just a matter of changing the habit as this sound does exist in the German language. Vv, vv. So, one just has to be carful when they're speaking that their mouth does not go into the ww position but rather the vv. Other words: visit, very, volleyball.
