You should just keep practising being familiar with the new vocabularies and try to use them in your daily life. Even if you watch movies,y ou may face with dificulties since you only focus on the words itself not to how to call/pronunciate.
The simple answer is: like in any language, in English there is a difference between what we write and what we say. I can help you with that. Check the About section of my Facebook page (EnglishFor Fluency) for details.
Watch movies with English subtitles and... try not to read the subtitles. Watch a scene without subtitles, observe how much you understood, than go back to the beginning and watch the same scene again, this time with subtitles.
