As far as language learning is concerned, regardless if it is Italian or not; people often learn easily and learn how to correctly use and pronounce foreign words if they have had the opportunity to hear those words from somebody who speaks the language naturally. Even if the words didn't come from a live Italian-native person, using video and audio materials are great sources of Italian pronunciation and accent which gives the listener proper cues.
If you have been doing this routine in order to learn the Italian language properly and inexpensively, you are in the right track. Aside from the fact that listening to Italian learners from your own neighbors, listening to Italian music or watching TV with Italian lines are the most convenient and recommended way to learn the language, it also ensures you of desirable results. All you need to do is just continue what you have started. But the essence of learning the Italian language through materials that you listen to lies by the way you listen intently to the words that you hear.
In order for you to apply and use correctly what you hear; make sure that you speak it. If it needs for you to speak like you are a real Italian, so be it. If that is the only way for you to improve your skills to learning and speaking Italian, there's no need to delay. Say what you need to say, in the most Italian way of saying it. You'll realize that you'll learn faster this way than by just thinking about where you shouldn't go wrong and what you should be really saying.
