Mixture the pronunciation of 2 languages

Do you have the experience that you mix the pronunciation of your mother tongue and a foreign language? If so, please share with us.

First of all I will share my experience with you here.
We know that the letters of French are nearly the same with English. When I began to learn French, the pronunciation was the first lesson for me. But after learning the pronunciation, I read all words that I saw in French way. My friends even called me crazy girl at that time. In a few weeks, after I practised it more, I solved the problem at last.
In my mind, that was a very intersting experience.
